section_title: Why GAO Did This Study
paragraphs: The Post-9/11 GI Bill was signed into law in June 2008 and provides educational assistance for veterans and members of the armed forces who served on or after September 11, 2001. The Department of Veterans Affairs (VA) is responsible for processing claims for these new education benefits. VA concluded that its legacy systems and manual processes were insufficient to support the new benefits and, therefore, began an initiative to modernize its benefits processing capabilities. The long-term solution was to provide a fully automated end-to-end information technology (IT) system to support the delivery of benefits by December 2010. VA chose an incremental development approach, called Agile software development, which is intended to deliver functionality in short increments before the system is fully deployed. GAO was asked to (1) determine the status of VA's development and implementation of its IT system to support the implementation of education benefits identified in the Post-9/11 GI Bill and (2) evaluate the department's effectiveness in managing its IT project for this initiative.
section_title: What GAO Found
paragraphs: VA has made important progress in delivering key automated capabilities to process the new education benefits. Specifically, it deployed the first two of four releases of its long-term system solution by its planned dates, thereby providing regional processing offices with key automated capabilities to prepare original and amended benefit claims. In addition, the Agile process allowed the department the flexibility to accommodate legislative changes and provide functionality according to business priorities. While progress has been made, VA did not ensure that certain critical tasks were completed that were initially expected to be included in the second release by June 30, 2010. For example, the conversion of data from systems in the interim solution to systems developed for the long-term solution was not completed until August 23, 2010. Because of the delay, VA planned to reprioritize the functionality that was to be included in the third release. Further, while VA plans to include full self-service capabilities to veterans, it will not do so in the fourth release as scheduled; instead it intends to provide this capability after the release or in a separate initiative. VA reported obligations and expenditures for these releases, through July 2010, to be approximately $84.6 million, with additional planned obligations of $122.5 million through fiscal year 2011. VA has taken important steps by demonstrating a key Agile practice essential to effectively managing its system development--establishing a cross-functional team that involves senior management, governance boards, key stakeholders, and distinct Agile roles. In addition, VA made progress toward demonstrating three other Agile practices--focusing on business priorities, delivering functionality in short increments, and inspecting and adapting the project as appropriate. Specifically, to ensure business priorities are a focus, VA established a vision that captures the project purpose and goals and established a plan to maintain requirements traceability. To aid in delivering functionality, the department established an incremental testing approach. It also used an oversight tool, which was intended to allow the project to be inspected and adapted by management. However, VA could make further improvements to these practices. In this regard, it did not (1) establish metrics for the goals or prioritize project constraints; (2) always maintain traceability between legislation, policy, business rules, and test cases; (3) establish criteria for work that was considered "done" at all levels of the project; (4) provide for quality unit and functional testing during the second release, as GAO found that 10 of the 20 segments of system functionality were inadequate; and (5) implement an oversight tool that depicted the rate of the work completed and the changes to project scope over time. Until VA improves these areas, management will lack the visibility it needs to clearly communicate progress and unresolved issues in its development processes may not allow VA to maximize the benefits of the system. To help guide the full development and implementation of the long-term solution, GAO is recommending that VA take five actions to improve its development process for its new education benefits system. VA concurred with three of GAO's five recommendations and provided details on planned actions, but did not concur with the remaining two.

section_title: Letter
paragraphs: In June 2008, Congress passed the Post-9/11 Veterans Educational  Assistance Act of 2008 (commonly referred to as the Post-9/11 GI Bill or  Chapter 33). This act amended Title 38 United States Code to include  Chapter 33, which provides educational assistance for veterans and  members of the armed forces who served on or after September 11, 2001.  The Department of Veterans Affairs (VA) is responsible for processing  claims for the Chapter 33 education benefit, which is a three-part benefit— tuition and fee payments, housing allowance, and book stipend.
In considering its implementation of the legislation, the department  concluded that it did not have a system capable of calculating the new  benefit. As a result, the department undertook an initiative to modernize  its education benefits processing capabilities. This initiative involved an  interim solution that augmented existing processes by providing  temporary applications to manually collect data and a long-term solution  to deliver automated processing capabilities. The department intended to  complete enough of the system functionality in the long-term solution to  replace the interim solution by June 2010, and to include additional  capabilities, such as interfaces to legacy systems, to provide a fully  automated end-to-end system to support the delivery of education benefits  by December 2010.
To develop the system for its long-term solution, VA is relying on  contractor assistance and is using an incremental development approach,  called Agile software development, which is to deliver software  functionality in short increments before the system is fully deployed. Agile  software development stresses the use of key practices such as working as  one team to define business priorities and, based on those priorities,  delivering work in short increments. Each increment of work is inspected  by the team and the project’s plans and priorities are adapted accordingly.
Given the importance of delivering education benefits to veterans and  their families, we were asked to review the long-term solution to    determine the status of VA’s development and implementation of its  information technology (IT) system to support the implementation of  education benefits identified in the Post-9/11 GI Bill, and    evaluate the department’s effectiveness in managing its IT project for this  initiative.
As agreed with your offices, on September 13, 2010, we provided briefing  slides that outlined the results of our study to staff of your Subcommittee  on Economic Opportunity. The purpose of this report is to provide the  published briefing slides to you and to officially transmit our  recommendations to the Secretary of Veterans Affairs. The slides, which  discuss our scope and methodology, are included in appendix I.
We conducted our work in support of this performance audit at the  Department of Veterans Affairs headquarters in Washington, D.C., and at a  contractor’s facility in Chantilly, Virginia, from November 2009 to  December 2010 in accordance with generally accepted government  auditing standards. Those standards require that we plan and perform the  audit to obtain sufficient, appropriate evidence to provide a reasonable  basis for our findings and conclusions based on our audit objectives. We  believe that the evidence obtained provides a reasonable basis for our  findings and conclusions based on our audit objectives.
In summary, our study highlighted the following:    VA has made important progress in developing and implementing the first  two of four releases of software planned for its new education benefits  processing system as scheduled, with these deployments occurring on  March 31, 2010, and June 30, 2010. In doing so, the department provided its  regional processing offices with key automated capabilities to prepare  original and amended benefit claims. It also responded to legislative  changes and provided for housing rate adjustments. While VA did not  previously estimate cost for these releases and, as such, could not track  estimated to actual costs, it reported that about $84.6 million had been  obligated through July 2010. The department noted that its Agile process  allowed the flexibility to adapt to legislative changes and provide  functionality according to business priorities.
However, VA did not ensure that certain critical tasks were completed that  were initially expected to be included in the second release by June 30,  2010. Specifically, the department did not complete the conversion of data  from systems in the interim solution to the systems developed for the long- term solution because it was found to be more complex than the  department had anticipated. The department also did not complete the  development of interfaces between the new system and legacy systems.  Program officials stated that data conversion was included along with  housing rate adjustments in a sub-release that was later deployed on  August 23, 2010. Because of these delays, VA planned to reprioritize what  functionality would be developed in its third release by September 30,  2010. For its fourth release, it intends to reduce its planned functionality of  providing full self-service capabilities to veterans by December 31, 2010.  The department intends to provide this capability after its fourth release or  under a separate initiative. As such, VA estimates that the total system  development actual and planned obligations through 2011 will be about  $207.1 million.
VA has demonstrated key Agile practices that are essential to effectively  managing its system development, but certain practices can be improved.  Specifically, the department ensured that teams represented key  stakeholders and that distinct Agile roles were fulfilled. For example, the  teams consisted of subject matter experts, programmers, testers, analysts,  engineers, architects, and designers. The department also made progress  toward demonstrating the three other Agile practices—focusing on  business priorities, delivering functionality in short increments, and  inspecting and adapting the project as appropriate. However, VA can  improve its effectiveness in these areas.
Business priorities. To ensure business priorities are a focus, a project  starts with a vision that contains, among other things, a purpose, goals,  metrics, and constraints. In addition, it should be traceable to  requirements. VA established a vision that captured the project purpose  and goals; however, it had not established metrics for the project’s  goals or prioritized project constraints. Department officials stated that  project documentation is evolving and they intend to improve their  processes based on lessons learned; however, until it identifies metrics  and constraints, the department will not have the means to compare  the projected performance and actual results of this goal. VA had also  established a plan that identified how to maintain requirements  traceability within an Agile environment; however, the traceability  between legislation, policy, business rules, and test cases was not  always maintained. VA stated that its requirements tool did not  previously have the capability to perform this function but now  provides this traceability to test cases. Nonetheless, if the department  does not ensure that requirements are traceable to legislation, policies,  and business rules, it has limited assurance that the requirements will  be fully met.
Deliver functionality in short increments. To aid in delivering  functionality in short increments, defining what constitutes completed  work (work that is “done”) and testing functionality is critical.  However, VA had not established criteria for work that was considered  “done” at all levels of the project. Program officials stated that each  development team had its own definition of “done” and agreed that  they needed to provide a standard definition across all teams. If VA  does not mutually agree upon a definition of “done” at each level,  confusion about what constitutes completed work can lead to  inconsistent quality and it may not be able to clearly communicate how  much work remains. In addition, while the department had established  an incremental testing approach, the quality of unit and functional  testing performed during Release 2 was inadequate in 10 of the 20  segments of system functionality we reviewed. Program officials stated  that they placed higher priority on user acceptance testing at the end of  a release and relied on users to identify defects that were not detected  during unit and functional testing. Until the department improves  testing quality, it risks deploying future releases that contain defects  which may require rework.
Inspect and adapt. In order for projects to be effectively inspected and  adapted, management must have tools to provide effective oversight. For  Agile development, progress and the amount of work remaining can be  reflected in a burn-down chart, which depicts how factors such as the  rate at which work is completed (velocity) and changes in overall  product scope affect the project over time. While VA had an oversight  tool that showed the percentage of work completed to reflect project  status at the end of each iteration, it did not depict the velocity of the  work completed and the changes to scope over time. Program officials  stated that their current reporting did not show the changes in project  scope because their focus was on metrics that are forward looking  rather than showing past statistics for historical comparison. However,  without this level of visibility in its reporting, management may not have  all the information it needs to fully understand project status.
subsections: section_title: Conclusions
paragraphs: VA deployed the first two of four releases of its long-term system solution  by its planned dates, therefore providing improved claims-processing  functionality to all regional processing offices, such as the ability to  calculate original and amended benefit claims. In addition, the Agile  process allowed the department the flexibility to accommodate legislative  changes and provide functionality according to business priorities, such as  housing rate adjustments. However, key features of the solution were not  completed as intended in the second release because the department  found some functionality to be more complex than anticipated.  Specifically, interfaces to legacy systems and the conversion of data from  systems in the interim solution were not completed as intended in the  second release. Due to these delays, VA planned to reprioritize what  functionality would be included in its third release. Also, for its fourth  release, the department had reduced a significant planned functionality— veteran self-service capability. While VA intends to provide this capability  after the fourth release within the long-term system solution or under a  separate initiative, it is unclear what functionality will be delivered in the  remaining two releases when it deploys the system in December 2010.
In using an Agile approach for this initiative, VA is applying lessons  learned and has taken important first steps to effectively manage the IT  project by establishing a cross-functional team that involves senior  management, governance boards, and key stakeholders. However, the  department had not ensured that several key Agile practices were  performed. Measurable goals were not developed and the project  progressed without bidirectional traceability in its requirements.  Additionally, in developing the system, VA did not establish a common  standard and consistent definition for work to be considered “done” or  develop oversight tools to clearly communicate velocity and the changes  to project scope over time. Testing deficiencies further hindered VA’s  assurances that all critical system defects would be identified. Until VA  improves these areas, management does not have the visibility it needs to  clearly communicate progress to stakeholders and estimate when future  system capabilities will be delivered. Additionally, reduced visibility and  unresolved issues in its development processes may result in the  department continuing to remove functionality that was expected in future  releases, thus delivering a system that does not fully and effectively  support the implementation of education benefits as identified in the Post- 9/11 GI Bill.
section_title: Recommendations for Executive Action
paragraphs: To help guide the full development and implementation of the Chapter 33  long-term solution, we recommend that the Secretary of Veterans Affairs  direct the Under Secretary for Benefits to take the following five actions:    establish performance measures for goals and identify constraints to  provide better clarity in the vision and expectations of the project;    establish bidirectional traceability between requirements and legislation,  policies, and business rules to provide assurance that the system will be  developed as expected;    define the conditions that must be present to consider work “done” in  adherence with agency policy and guidance;  implement an oversight tool to clearly communicate velocity and the  changes to project scope over time; and  improve the adequacy of the unit and functional testing processes to  reduce the amount of system rework.
section_title: Agency Comments and Our Evaluation
paragraphs: We received written comments on a draft of this report from the Secretary  of Veterans Affairs and VA’s Assistant Secretary for Information and  Technology. In the Secretary’s comments, reproduced in appendix II, VA  concurred with three of our recommendations and did not concur with  two recommendations. Specifically, the department concurred with our  recommendation to establish performance measures for goals and identify  constraints to provide better clarity in the vision and expectations of the  project. VA noted that it plans to develop performance measures  consistent with automating the Post-9/11 GI Bill by March 2011. While this  is a positive step, as we noted, it is also important that the department  identify any project or business constraints to better clarify the vision and  expectations of the system. VA also concurred with our recommendation  that it establish bidirectional traceability between requirements and  legislation, policies, and business rules to provide assurance that the  system will be developed as expected. The department stated that it plans  to establish traceability between its business rules for the long-term  solution and the legislation by June 2011. Additionally, VA concurred with  our recommendation to define the conditions that must be present to  consider work “done” in adherence with department policy and guidance.  VA noted that the initiative’s fiscal year 2011 operating plan outlines these  conditions at the project level and that it intends to clarify the definition at  the working group level by December 2010.
VA did not concur with our recommendation that it implement an  oversight tool to clearly communicate velocity and the changes to project  scope over time. The department indicated that development metrics and  models had already been established and implemented to forecast and  measure development velocity. In this regard, as our briefing noted,  department officials stated that they previously reported project-level  metrics during the first release, and based on lessons learned, decided to  shift to reporting metrics at the development team level. While it is  important that VA established the capability to track team-level metrics, it  is also important to track and clearly report how changes to the system  development at the team level affect the overall project-level scope over  time. Specifically, without the overall velocity—a key mechanism under  the Agile methodology—VA does not have the information to understand  the expected effort to complete the total scope of work and the associated  length of time to do so. The overall velocity provides an understanding of  the complexity and difficulty in accomplishing tasks and provides VA  management with information to better understand project risks. This  visibility is a key concept of the Agile methodology that VA has chosen to  implement for this project. Without this level of visibility in its reporting,  management and the development teams may not have all the information  they need to fully understand project status and generate the discussion  and feedback necessary for continuous process improvement. Therefore,  we continue to believe that our recommendation for VA to clearly  communicate velocity and project scope changes can only strengthen the  department’s development process to be more in line with Agile system  development practices.
VA also did not concur with our recommendation to improve the adequacy  of the unit and functional testing processes to reduce the amount of  system rework. While the department noted that its testing approach is  compatible with Agile development, it also acknowledged in other  technical comments the department provided that there were instances of  inconsistencies of user stories for capabilities being marked “done” and  the user stories we reviewed during the second release showed significant  weaknesses in the quality of testing performed. While we agree that VA’s  testing approach is consistent with Agile methodology, these weaknesses  we identified demonstrate ineffective testing and the need for a consistent  and agreed-upon definition of “done.” Further, the program officials noted  that their approach focused on users identifying defects at the end of the  release, which, as we have noted, can be problematic because it is difficult  for users to remember all the items and parameters needed for  functionality. Without increased focus on the quality of testing early in the  development process, VA risks delaying functionality and/or deploying  functionality with unknown defects that could require future rework that  may be costly and ultimately impede the claims examiners’ ability to  process claims efficiently. Therefore, we continue to believe that our  recommendation to improve the adequacy of unit and functional testing is  needed to improve the effectiveness of VA’s process called for in the Agile  methodology. This would provide stakeholders greater assurance that  functionality developed during each iteration is of releasable quality  before it is presented to users as completed work in accordance with Agile  system development practices.
In addition, VA provided other technical comments on a draft of this  report. In the comments, the department provided additional clarification  on why there were delays to functionality and how they affected the  release schedule. Specifically, the department stated that the governance  structure it established for the initiative provided the necessary  management, support, and prioritization of development efforts to balance desired functionality within the development challenges and constraint The department noted that, among other things, delays in the firs t two  releases were a result of additional functionality prioritized and developed, such as housing rate adjustments and the ability to  automatically generate letters for veterans as well as unanticipated  challenges, such as the complexity of data conversion tasks. Further, it  noted that decisions and prioritizations were primarily made to min impact on field offices and to support fall enrollment and that they  impacted the development capacity to support the capabilities tha be developed in the third release. VA also offered oth comments which were incorporated as appropriate.  s.
Beyond the department’s comments on our recommendations, the  Assistant Secretary for Information and Technology provided additional  written comments, reproduced in appendix III, which noted concerns with our draft report. In these comments, the Assistant Secretary stated that the department believes we fell short of meeting the objectives for this repo by omitting key facts and presenting an unnecessarily negative view of VA’s status and effectiveness to Congress. In particular, the Assistant  Secretary stated that VA had successfully converted all processing of new  Post-9/11 GI Bill claims to the long-term solution prior to the  commencement of the fall 2010 enrollment process and that processing with the new system has been nearly flawless. He added that Veterans  Business Administration claims processors like the new system and find it easy and effective to use. We are encouraged to hear that the department   that  is experiencing positive results from the system development efforts have been accomplished. However, as noted in our briefing, system  functionality that was envisioned to (1) provide self-service capabilities to  as  veterans and (2) end-to-end processing of benefits by December 2010 w deferred. Further, as the vision for its new education benefits system  evolves, it is essential that the department documents these changes to  ensure that its expecta aligned at all levels.    tions and goals for the system are measurable and  In addition, the Assistant Secretary stated that limited exposure to the  Agile methodology possibly caused us to present incorrect assumptions as facts, such as our evaluation of the department’s testing. Our audit team,  which included a trained ScrumMaster, examined the department’s use of  Agile Scrum practices against documented and accepted methodologies  and consulted with an expert in the field that is not only a ScrumMaster,  but also an Agile Scrum trainer that has extensive experience in evalu ating  Agile system development projects. At the initiation of our study, we  discussed our evaluation approach with program officials and throughout  the study, held meetings with them to ensure our full understanding of the  department’s requirements and testing processes. We did not take issue  with the Agile testing approach used by VA. However, we found  deficiencies in testing. Further, we presented the results of our  observations to program officials in June 2010, at which time they did not  express any such concerns, or otherwise comment on our evaluation of  the testing. Further, given the evolving nature of Agile system  development, it is important to ensure that work that is presented as  “done” and demonstrated to the users at the end of an iteration has  undergone adequate testing to prevent inaccurate information from being  provided. In addition to weaknesses we identified in the testing of select  user stories, the department identified a number of defects during the  development of the second release. In our view, VA has an opportunity to  improve the adequacy of its unit and functional testing which occurs  during each iteration to help identify and resolve any defects before any  related functionality is presented to users as completed work at the end of  the iteration. As we noted, the department agreed that they needed to  clarify their definition of “done” and ensure it is being applied consistently.  As such, the definition often includes fully tested functionality that has no  defects. During our review, we observed on multiple occasions work being  presented as “done” without having completed all testing. Improved  testing up front can reduce the amount of defects found later in user  acceptance testing and production that would require more costly rework.
Further, the Assistant Secretary stated that the department believes that  we missed a substantial opportunity to positively influence real change by  not focusing on the fact that VA had adopted the Agile methodology after  many failings with other IT systems development efforts that used  waterfall development methodologies. We agree that VA has taken an  important step toward improving its development capability and that it has  developed significant segments of its new education benefits system with  its new methodology. However, as we noted in our briefing, the  department had not fully established metrics for its goals, which are  essential to fully gauge its progress beyond past initiatives.
While we believe that VA has made substantial progress in implementing a  new process to develop its system, we stand by our position that there is  still an opportunity for the department to improve its new development  process in accordance with our recommendations. Doing so would further  increase the likelihood that VA fully develops and delivers the end-to-end  benefits processing capabilities envisioned to support the Post-9/11 and the needs of veterans.

section_title: Appendix I: Briefing for Staff Members of the Subcommittee on Economic Opportunity, Committee on Veterans’ Affairs, House of Representatives
subsections: section_title: Information Technology: Veterans Affairs Can Improve Its Development Process for Its New Education Benefits System
section_title: Attachment III
paragraphs: In June 2008, Congress passed the Post-9/11 Veterans Educational Assistance Act of  2008 (commonly referred to as the Post-9/11 GI Bill or Chapter 33). This act amended  Title 38 United States Code to include Chapter 33, which provides educational assistance  for veterans and members of the armed forces who served on or after September 11,  2001.
The Department of Veterans Affairs (VA) is responsible for processing claims for the  Chapter 33 education benefit, which is a three-part benefit—tuition and fee payments,  housing allowance, and book stipend. The benefit is determined based upon an  individual’s aggregate qualifying active duty service.
A key milestone in the Chapter 33 legislation was the requirement that VA provide the  new educational assistance benefits to service members and veterans beginning on  August 1, 2009. In considering its implementation of the legislation, the department  concluded that it did not have a system capable of calculating the new benefit. As a  result, the department undertook an initiative to modernize its education benefits  processing capabilities. . 5001-5003, Jne 30, 2008.
VA’s initiative to modernize its education benefits processing involved interim and long- term solutions to deliver new processing capabilities. According to the department, the  interim solution was intended to augment existing processes by providing temporary  applications and tools, such as a spreadsheet that aided claims examiners in manually  collecting data from VA legacy systems and to calculate the new benefits.
At the same time that it began the interim solution, the department also initiated a long- term solution that was intended to fully automate the manual processes for calculating  education benefits for service members and veterans. Specifically, the long-term solution  was intended to provide a system to replace the interim solution as well as provide  automated interfaces with existing legacy systems. The department intended to complete  enough of the functionality in the long-term solution to replace the interim solution by June  2010, and to include additional capabilities for full deployment of the new education  benefits system by December 2010. legcy tem, mong other, inclde  finncil pyment tem, n edtion informtion tem, nd  veterdemogrphic nd ervice d tem.

To develop the system for its long-term solution, VA is relying on contractor assistance  and is using an incremental development approach, called Agile software development,  which is to deliver software functionality in short increments before the system is fully  deployed. Agile software development has key practices such as working as one team.  This one team is to define business priorities and, based on those priorities, deliver work  in short increments. Each increment of work is inspected by the team and the project’s  plans and priorities are adapted accordingly.
Historically, VA has experienced significant IT development and delivery difficulties. In the  spring of 2009, the department reviewed its inventory of IT projects and identified ones  that exhibited serious problems with schedule slippages and cost overruns. The  department noted that an incremental approach, such as Agile software development,  was considered to be an effective way to support the long-term system solution  development. oftwre development i not  et of tool or  ingle methodology, bu philoophy based on elected v such as, the  highet priority i to satify customer throgh erly nd continus delivery of vuable oftwre, delivering working oftwre  freqently, from  cople of week to  cople of month, nd tht working oftwre i the primry measure of progress.

Given the importance of delivering education benefits to veterans and their families, we  were asked to review the long-term solution to    determine the status of VA’s development and implementation of its information  technology (IT) system to support the implementation of education benefits identified  in the Post-9/11 GI Bill and    evaluate the agency’s effectiveness in managing its IT project for this initiative.
To determine the status of VA’s development and implementation of IT system to support  the implementation of education benefits identified in the Post-9/11 GI Bill, we    reviewed VA and contractor plans for system development, observed project status  meetings, and compared the actual status of development and implementation to the  planned status, and     discussed the department’s plans and implementation with VA and contractor  officials to determine the functionality completed and demonstrated. . 5001-5003 nd Pub.

7     analyzed requirements and testing artifacts for 20 segments of system features  developed to determine the traceability of requirements and testing coverage;    observed key agency and contractor development meetings such as daily  discussions, bi-weekly software reviews and planning meetings, where management  decisions were made and Agile practices were demonstrated; and     interviewed department and contractor officials about the management and  oversight of requirements, testing, and transition plans.
The information on cost estimates and costs that were incurred for long-term solution  development were provided by VA officials. We did not audit the reported costs and thus  cannot attest to their accuracy or completeness.
We conducted this performance audit at the Department of Veterans Affairs headquarters  in Washington, D.C., and at a contractor facility in Chantilly, Virginia, from November  2009 to September 2010 in accordance with generally accepted government auditing  standards. Those standards require that we plan and perform the audit to obtain  sufficient, appropriate evidence to provide a reasonable basis for our findings and  conclusions based on our audit objectives. We believe that the evidence obtained  provides a reasonable basis for our findings and conclusions based on our audit  objectives.
VA has developed and implemented the first two of four releases of software planned for  its new education benefits processing system as scheduled, with these deployments  occurring on March 31, 2010, and June 30, 2010. In doing so, VA provided its regional  processing offices with key automated capabilities to prepare original and amended  benefit claims. In addition, VA responded to legislative changes and provided for housing  rate adjustments. While VA did not previously estimate costs for these releases and, as  such, could not track estimated to actual costs, it has reported that about $84.6 million  has been obligated through July 2010. The department noted that its Agile process  allowed the flexibility to adapt to legislative changes and provide functionality according to  business priorities. However, VA did not ensure that certain critical tasks were performed  that were expected to be part of the second release. Specifically, it did not complete the  conversion of data from systems in the interim solution to the systems developed for the  long-term solution and did not complete the development of interfaces between the new  system and legacy systems. nned to complete interfce to ll legcy tem except for it finncil pyment tem, which i plnned for the third release.
Further, because of these delays, VA is in the process of determining and prioritizing what  functionality will be developed in its third release by September 30, 2010. For its fourth  release, it intends to reduce its planned functionality of providing full self-service  capabilities to veterans by December 31, 2010. However, VA intends to provide this  capability after its fourth release or under a separate initiative. As such, VA estimates that  the total system development actual and planned obligations through 2011 will be about  $207.1 million. er repreent ctual expenditre, oligted fnd, nd plnned oligted fnd throgh fil yer 2011.
VA has demonstrated key Agile practices that are essential to effectively managing its  system development, but certain practices can be improved. Specifically, the department  has ensured that teams represent key stakeholders and that specific Agile roles were  fulfilled. For example, the teams consist of subject matter experts, programmers, testers,  analysts, engineers, architects, and designers. The department has also made progress  toward demonstrating the three other Agile practices—focusing on business priorities,  delivering functionality in short increments, and inspecting and adapting the project as  appropriate. However, VA can improve its effectiveness in these areas. Specifically:    To ensure business priorities are a focus, a project starts with a vision that contains,  among other things, purpose, goals, metrics, and constraints. In addition, it should  be traceable to requirements. VA has established a vision that captures the project  purpose and goals; however, it has not established metrics for the project’s goals or  prioritized project constraints. VA officials stated that project documentation is  evolving and they intend to improve their processes based on lessons learned;  however, until it identifies metrics and constraints, the department will not have the  means to compare the projected performance and actual results of this goal. VA has  also established a plan that identifies how to maintain requirements traceability  within an Agile environment; however, the traceability between legislation, policy,  business rules, and test cases was not always maintained. VA stated its   11   requirements tool did not previously have the capability to perform this function and  now provides this traceability to test cases. Nonetheless, if VA does not ensure that  requirements are traceable to legislation, policies, and business rules, it has limited  assurance that the requirements will be fully met.
To aid in delivering functionality in short increments, defining what constitutes  completed work (work that is “done”) and testing functionality is critical. However,  VA has not yet established criteria for work that is considered “done” at all levels of  the project. Program officials stated that each development team has its own  definition of “done” and agreed that they need to provide a standard definition across  all teams. If VA does not mutually agree upon a definition of “done” at each level,  confusion about what constitutes completed work can lead to inconsistent quality  and it may not be able to clearly communicate how much work remains. In addition,  while the department has established an incremental testing approach, the quality of  unit and functional testing performed during Release 2 was inadequate in 10 of the  20 segments of system functionality we reviewed. Program officials stated that they  placed higher priority on user acceptance testing at the end of a release and relied  on users to identify defects that were not detected during unit and functional testing.  Until the department improves testing quality, it risks deploying future releases that  contain defects which may require rework. tht the delivery of completed oftwre e defined, commonly referred to as the definition of “done.”  Thi criticl to the development process to help ensure tht, mong other thing, teting has een dequately performed nd the  reqired docmenttion has een developed.
In order for projects to be effectively inspected and adapted, management must  have tools to provide effective oversight. For Agile development, progress and the  amount of work remaining can be reflected in a burn-down chart, which depicts how  factors such as the rate at which work is completed (velocity) and changes in overall  product scope affect the project over time. While VA has an oversight tool that  shows the percentage of work completed to reflect project status at the end of each  iteration, it does not depict the velocity of the work completed and the changes to  scope over time. Program officials stated that their current reporting does not show  the changes in project scope because their focus is on metrics that are forward  looking rather than showing past statistics for historical comparison. However,  without this level of visibility in its reporting, management may not have all the  information it needs to fully understand project status.
To help ensure successful implementation of the Chapter 33 initiative, we are  recommending that VA establish performance measures for goals and identify  constraints; establish traceability between requirements and legislation, policies, and  business rules; define the conditions that must be present to consider work “done;” review  and improve the unit and functional testing processes; and implement an oversight tool to  clearly communicate velocity and the changes to project scope over time.
We received oral comments on a draft of this briefing from VA officials, including the  Deputy Assistant Secretary for Congressional and Legislative Affairs and the Assistant  Secretary for Information and Technology. In their comments, the officials stated that the  department was not in a position to concur or not concur with our recommendations, but  planned to provide formal comments on our final report. The officials also provided  technical comments, which we have incorporated in the briefing as appropriate.
In recognition of their service to our country, VA provides medical care, benefits, social  support, and lasting memorials to veterans, service members, and their families. VA is the  second largest federal department with more than 270,000 employees. In fiscal year  2009, the department reported incurring more than $100 billion in obligations for its  overall operations.
The Veterans Benefits Administration (VBA), one of VA’s three line administrations,  provides assistance and benefits, such as educational assistance, through four veterans’  regional processing offices. In 2009, the department reported that it provided more than  $3.5 billion in educational assistance benefits to approximately 560,000 individuals. In  2011, it expects the number of all education claims to grow by 32 percent over 2009,  increasing from 1.7 million to 2.25 million. two other line dminitrtion re the Veter Helth Adminitrtion nd the Ntionl Cemetery Adminitrtion.  l processing office re locted in Atlnt, Georgi; Bfflo, New York; Muskogee, Oklhom; nd St. Lo, Missri.
16   insufficient to support the demands for processing the new benefit.
In October 2008, VA established its Chapter 33 initiative to develop the capability to  process the new education benefit. The initiative involved both an interim and long-term  solution:     The interim solution, deployed in November 2009, provided applications and tools,  such as a spreadsheet that aided claims examiners in manually collecting data from  VA legacy systems to calculate the new education benefit.
The long-term solution was expected to be complete enough to replace the interim  solution by June 2010 and to include additional capabilities to provide a fully  automated end-to-end system to support the delivery of education benefits by  December 2010.
Among other features, by December 2010, the new education benefits system was to    modernize processing of new Chapter 33 awards and amended existing Chapter 33  claims, to include automated calculations of benefits, such as tuition and fee  payments, housing allowance, and book stipends;     increase claims processing efficiency to all regional offices, such as providing  capability to automatically access veteran demographic and service data;    interface with VA’s existing legacy systems that contain information required to  calculate benefits, such as a financial payment system; and    create veteran self-service capabilities such as the capability to estimate and apply  for benefits online.
To oversee the development and implementation of the new education benefits system,  VA has formed a governance structure that includes executive level management from  VBA and the department’s Office of Information and Technology (OI&T). The VBA Under  Secretary of Benefits has primary responsibility for coordinating the Chapter 33 initiative.  For example, the Under Secretary ensures collaboration for the effective management  and coordination of VA resources in support of the Chapter 33 implementation.
To develop and implement the long-term solution, VA’s OI&T entered into an interagency  agreement with the Department of Defense’s Space and Naval Warfare Systems Center– Atlantic (SPAWAR) to develop the long-term solution. SPAWAR is managing multiple  contractors to develop the system and is providing technical, information assurance, and  program management services. SPAWAR is also providing operational services and  engineering, planning, and analysis to support application development. VA and  SPAWAR work together to manage and develop the system. Specifically, VBA subject  matter experts and OI&T technical representatives are part of the system development  teams. , contrctor such as Agilex Technologie, Inc., Booz Allen Hmilton, GeoLogic, nd Lockheed Mrtin, support the  Chpter 33 tem development.
section_title: To develop and implement the new system, VA also is following its Project Management Accountability System (PMAS) framework which was established in June 2009. PMAS requires that the department’s IT projects adopt an iterative release schedule in which system features are delivered within firm, 6-month (or less) cycles. Consistent with the framework, the department established four release dates for the Chapter 33 long-term solution. Each release was to deploy incremental capabilities that would expand upon previously developed functionality.

section_title: While VA did not originally estimate the total cost to implement the long-term solution, nor estimate its cost by release, as of July 2010, program officials reported actual and planned obligations of approximately $207.1 million through fiscal year 2011.

section_title: To develop and implement the long-term solution according to the planned release schedule, VA is using an Agile software development approach, which places an emphasis on collaboration between developers and stakeholders and produces a system in an iterative and incremental fashion. Agile software development is recognized as having fundamental differences from traditional methods. For example, it is an iterative process in which each output (which can range between 1 and 8 weeks in duration) provides a segment of system functionality that is developed, tested, and demonstrated to users so that early feedback can be considered. A segment of functionality could be a computer screen to display the amount a beneficiary would be entitled to. However, with a traditional approach, the complete product is often delivered at the end of the development phase of the system lifecycle and is not performed in short iterative segments.

section_title: Work as one team. In Agile development, project participants view themselves as one team aimed at a common goal. However, while the participants should work together as one whole team, there are specific roles on the team.
paragraphs: Product owner. The product owner’s primary duties include making sure that all  team members are pursuing a common vision for the project, establishing priorities  so the highest-valued functionality is always being worked on, and making decisions  that lead to a good return on investment. rief hitory on itertive nd incrementl development nd the origin of Agile method, ee Crnegie Mellon Softwre  Engineering Intitte, Hillel Glzer, et l., CMMI® or Agile: Why Not Embrace Both!

section_title: Team member. The team member’s role often includes programmers, testers,
paragraphs: analysts, database engineers, usability experts, technical writers, architects, and  designers. The team members are responsible for developing high-quality  functionality as prioritized by the product owner.
Project manager. The project manager focuses more on leadership than on  management and is a facilitator for the team working together. In addition, he or she  is responsible for removing project obstacles that may impede the team’s  performance.
Additionally, best practices state that it is essential for a systems development team to  have involvement from other stakeholders, such as executive level management and  senior management. Such involvement helps to minimize project risk by ensuring that  key requirements are identified and developed, problems or issues are resolved, and  decisions and commitments are made in a timely manner. titte of Electricnd Electronic Engineer (IEEE), Stem nd oftwre engineering – oftwre life cycle process, IEEE Std.  12207-2008, (Piy, N.J., Juary 2008) nd Crnegie Mellon Softwre Engineering Intitte, CMMI for Development, Verion  1.2, CMU/SEI-2006-TR-008 (Pittsburgh, Penn., Aust 2006).
section_title: Focus on business priorities. Agile teams demonstrate customer collaboration and commitment to business priorities in two ways. First, the product owner prioritizes and determines the order in which features will be developed. A release plan is then created that states how much work the team can accomplish by a certain date. Second, Agile teams focus on completing and delivering user-valued features, usually in the form of user stories, which are a way of expressing software requirements. A user story is a brief description of functionality as viewed by a user or customer of the system. User stories are gathered and documented throughout the development process.
section_title: During the iteration, each piece of functionality or feature worked on should be determined to be of releasable quality, before it is presented as completed work. The criteria for making the determination is the definition of done. Only work that is completed should be presented during a review meeting that takes place at the end of an iteration. Because a single iteration does not usually provide sufficient time to complete enough new functionality to satisfy user or customer desires, a release, which is typically 2 to 6 months and is comprised of one or more iterations, identifies a desired set of functionality and the projected time frame it will be ready for users and customers.
section_title: Inspect and adapt. Agile teams demonstrate the value of responding to change by incorporating knowledge gained in the preceding iteration and adapting plans accordingly at the start of the next iteration. This is intended to facilitate continuous process improvement. For example, the accuracy of the release plan may be affected by the team’s discovery that it has overestimated or underestimated its rate of progress in that software development is more time consuming; therefore, the release plan should be revisited and updated regularly. Further, it may be the case that based on seeing the software from an earlier iteration, the product owner learns that users would like to see more of one type of feature and that they do not value another feature as much as originally planned. The value of the plan could be increased in this case by moving more of the desired features into the release and postponing some of the lesser-valued features. This recognizes that planning is an ongoing process that takes place during the entire project in order to deliver a valuable solution to the users.
section_title: These practices are important to any Agile framework, including the one VA has chosen to implement called Scrum. Scrum emphasizes developing software in increments and producing segments of functionality that are tested and demonstrated to users. In addition, Scrum teams are interactive and cross-functional in developing these segments throughout each iteration. See attachment I for a discussion of the specific practices and predefined roles within the Scrum framework for managing software development.

section_title: VA deployed Release 1 of the long-term solution on March 31, 2010, as scheduled, providing a limited set of claims examiners at the four regional processing offices the ability to calculate tuition, housing allowance, books, stipends, and fees for processing original awards of education benefits. However, the release did not provide planned functionality to process claims for amended awards or to convert and transfer beneficiary data from systems that were part of the interim solution to systems for the long-term solution. VA officials stated that the processing of amended awards and the data conversion task were found to be more complex than they had originally anticipated and therefore, the functionality was delayed for completion in Release 2.
section_title: In addition, despite having delayed the conversion of data from the interim solution to the long-term solution until Release 2, this task was not completed. As a result, VA created a sub-release, Release 2.1, with the intent of completing data conversion and adding selected functionality, such as the 2010 housing rate adjustments, by July 26, 2010; however, program officials stated that Release 2.1 was actually deployed on August 23, 2010. With this release, program officials stated that approximately 30,000 out of 550,000

section_title: Further, program officials stated that the department has not yet decided how the delay of Release 2.1 will affect the interfaces that were to be developed in Release 3, which is still planned to be deployed by September 30, 2010. As such, program officials stated that they would decide in September how much of the Release 3 functionality could be completed by the scheduled date. In addition, they also stated that they have reduced functionality of the system and the self-service capability will not be included as planned in Release 4 when it is deployed in December 31, 2010. However, the department plans to provide this self-service capability after Release 4 within the long-term system solution or under a separate initiative. The department is in the process of defining what the self- service capability will include.
section_title: To provide effective management for an Agile project, such as the development of the Chapter 33 long-term solution, a key component for success is demonstrating effective use of the Agile practices: working as one team, focusing on business priorities, delivering functionality in short increments, and inspecting and adapting the project as appropriate. While VA has taken an important step to effectively manage its development of the system for processing Chapter 33 educational benefits by establishing a cross-functional team, it has not yet fully ensured business priorities are a focus, demonstrated that it is delivering quality functionality in short increments, or provided mechanisms to enable inspection and adaptation of the project. As a result, VA does not have the visibility it needs to clearly communicate progress to stakeholders and may not be able to generate feedback necessary for effectively establishing project priorities and continuous process improvements.
section_title: VA has established a team of executive level management that fulfills the role of the product owner. For example, the team consists primarily of executives and senior managers from VBA and the department’s OI&T, who are members of two decision- making bodies for the initiative: the Joint Executive Board and Executive Steering Committee. They meet weekly to discuss the vision and make decisions on functionality, schedule, and cost issues. VA has also established additional workgroups that provide daily leadership, oversight, and operations management for the systems development effort and serve as extensions of the product owner to identify and prioritize requirements. (For detailed information about the responsibilities and leadership

The department has also established multiple, cross-functional teams to develop the  system. These teams consist of VA subject matter experts as well as contractors that are  programmers, testers, analysts, database engineers, architects, and designers. These  teams hold daily Scrum meetings to discuss work that has been planned and  accomplished, and any impediments to completing the work. At the completion of each  iteration, which in VA’s case is every 2 weeks, a review meeting occurs between the  cross-functional teams and VA stakeholders to review and demonstrate completed  system functionality. Following this meeting, planning sessions are held to discuss the  work to be accomplished in the next iteration based on the next highest-prioritized  requirements contained in user stories.
In addition, VA has identified project managers from both VA and SPAWAR that focus on  leadership of the initiative. These project managers monitor and facilitate meetings and  provide clarification to contractors, subject matter experts, and other developers. They are  also responsible for addressing impediments discussed at the review meetings.
With this involvement from key stakeholders, VA has established a team structure that  fulfills the key roles within an Agile team and has better positioned itself to effectively  manage the initiative.
section_title: Under an Agile methodology, to ensure business priorities are a focus, a project starts with a vision of the system that is communicated to the team by the product owner. This vision should clearly state the purpose and goals of the project; the goals should be measurable; and constraints should be identified and prioritized to establish project parameters related to scope, cost, and schedule. In addition, well-defined and managed requirements are a cornerstone of effective system development. According to recognized guidance, disciplined processes for developing and managing requirements can help reduce the risks of developing a system that does not meet user and operational needs. Such processes include establishing policies and plans for managing changes to requirements and maintaining bidirectional requirements traceability. As such, the project vision should be traceable to requirements and functionality developed, which is contained in user stories.

section_title: However, the department has not established metrics for the project’s goals, prioritized project constraints, or ensured that requirements were fully traceable to legislation, policies, and business rules. Specifically, the goals that VA has established do not have metrics for determining the progress towards achieving the goals. For example, for VA’s goal to maximize the user experience, the department has not established a quantifiable, numerical target or other measurable value to facilitate future assessments of whether the goal was achieved. As a result, the department does not have the means to compare the projected performance and actual results of this goal.
section_title: VA also did not always ensure that requirements for Release 2 were traceable. While the department has established a plan that identifies the process that the team is to follow to transform requirements into user stories and the tools it is to utilize to maintain traceability, our review of selected user stories in Release 2 found that traceability between legislation, policy, business rules, and test cases was not always maintained and, therefore, could not be verified. For example, requirements in the 20 user stories we reviewed in Release 2 were not traceable to legislation, nor were we able to observe how requirements were traceable to all the test cases that covered the complete requirement.
section_title: Further, officials acknowledged that the department’s requirement tool did not have the capability to fully establish software traceability for Release 2, but that VA has since upgraded its tool. The officials stated the department will be able to provide this level of traceability to test cases in future releases. While program officials acknowledged the importance of traceability and the need to improve their process, they have not identified how the department will effectively establish bidirectional traceability between system requirements and legislation, policy, and business rules. Until the department can effectively ensure that requirements are fully traceable to legislation, policies, business rules, and test cases it will continue to have a limited ability to reasonably assure that the Chapter 33 requirements will be completely met.
paragraphs: rtment offici noted tht prior to thi pgrde, they were able to eablih trceability to tet casually.
section_title: While the department has defined some criteria for work that is considered “done” at the release level, VA has not defined what it means at the user story, iteration, or project level. We observed multiple cases during Release 2 development in which user stories were presented as “done,” but had varying amounts of work completed. For example, at three iteration review meetings, we observed at least one development team that
paragraphs: er 1998); Information  Technology: Customs Automated Commercial Environment Progressing, but Need for Management Improvements Continues, GAO- 05-267 (Washington, D.C.: Mr. 14, 2005); nd Homeland Security: Visitor and Immigrant Status Program Operating, but Management  Improvements Are Still Needed, GAO-06-318T (Washington, D.C.: Jn. 25, 2006). presented user stories as “done” without having completed all testing.
Program officials stated that each development team has their own definition of “done”  and agreed that they need to provide a standard definition across all teams. If VA does  not mutually agree upon and document this definition at each level and ensure it  conforms to the department’s standards, conventions, and guidelines, confusion about  what constitutes completed work could lead to inconsistent quality and unreliable  performance and progress reporting. Further, in the absence of an agreed-upon  definition, VA is not able to clearly communicate how much work remains for completing  the system.
section_title: With regard to testing, VA has established an incremental testing approach that calls for automated unit and functional testing to be conducted on work completed during iterations. In addition, it has also established user acceptance testing that is performed before a release is delivered. Nonetheless, we found that the unit and functional testing performed during Release 2 was inadequate. Specifically, in reviewing the testing conducted for 20 user stories, we identified the testing to be inadequate for 10 of them. For these 10 user stories, we identified a total of 19 deficiencies covering a range of issues.
paragraphs: rther informtion on nit nd fnctionl teting, ee GAO, Indian Trust Funds: Challenges Facing Interior’s Implementation of  New Trust Asset and Accounting Management System, GAO/T-AIMD-99-238 (Washington, D.C.: Jl. 14, 1999) nd GAO, Financial  Management Systems: Additional Efforts Needed to Address Key Causes of Modernization Failures, GAO-06-184 (Washington, D.C.:  Mrch 27, 2006).
section_title: For example, 7 user stories were not fully tested for expected values or boundary conditions specified in their associated requirements documents. These testing deficiencies may hinder VA’s ability to identify critical defects. VA and contractor system development and testing teams subsequently identified a number of defects during Release 2. Specifically, program officials stated that 218 of the 423 defects that were to be corrected in Release 2 were classified as high priority. For example, user acceptance testing found that an award letter included the incorrect date for a student’s enrollment period. Program officials stated that all of the high-priority defects were corrected or closed as invalid and that they are working toward correcting the remaining defects in future iterations.
paragraphs: er were reported as of Jne 29, 2010. Progrm offici decried high-priority defect as defect tht cold “rek” the  tem nd muse fixed.
section_title: Program officials also stated that they placed higher priority on user acceptance testing at the end of a release and relied on users to identify defects that were not detected during unit and functional testing. However, as we have noted, relying on subject matter experts to perform user acceptance testing is not a realistic solution because it is difficult for them to remember all the items needed for functionality. Further, while program officials stated that many of the defects were closed before Release 2 was fully deployed, due to the inadequate testing the potential exists for a significant number of additional defects to be found after deployment, thus requiring system rework which can increase costs and affect schedule. Until the department improves testing quality, it risks deploying future releases that contain defects which may require rework and extend the completion date for the project. Ultimately, this could increase the risk of delayed functionality that would impede the ability for claims examiners to process claims efficiently.
paragraphs: tion on how defect result in nplnned rework nd increased co, ee GAO-06-184.
section_title: In order for projects to be effectively inspected and adapted, management must have tools to provide visibility to communicate progress to stakeholders. Under the Scrum framework, project visibility is achieved through the use of specific tools. For example, progress and the amount of work remaining across the release is demonstrated by a burn-down chart. Specifically, a burn-down chart can depict how factors such as the rate at which work is completed (velocity) and changes in overall product scope affect the project over time. This information can be forecasted to estimate how long a release will take to complete. Further, when compared to the project rate of work completion, the chart can provide visibility into the actual project status and can be used for continuous process improvement such as increasing the accuracy of estimating story points for future user stories.
section_title: Since the department did not use a burn-down chart to report performance over time, management and stakeholders cannot clearly discern the actual amount of work completed relative to the amount of work that was expected to be completed. Without this level of visibility in its reporting, management and the development teams may not have all the information they need to fully understand project status and generate the discussion and feedback necessary for continuous process improvement.
paragraphs: m offici ted tht they hd previously used  burn-down chrt thhowed velocity for ll te in Release 1. However, in  Release 2, they decided tht they wold provide burn-down chrt t the tem level, but not t the overll project level.
To help guide the development and implementation of the Chapter 33 long-term solution,  we recommend that the Secretary of Veterans Affairs direct the Under Secretary for  Benefits to take the following five actions:    establish performance measures for goals and identify constraints to provide better  clarity in the vision and expectations of the project;     establish bidirectional traceability between requirements and legislation, policies,  and business rules to provide assurance that the system will be developed as  expected;     define the conditions that must be present to consider work “done” in adherence with  agency policy and guidance;     improve the adequacy of the unit and functional testing processes to reduce the  amount of system rework; and     implement an oversight tool to clearly communicate velocity and the changes to  project scope over time.
48     Agency Comments and Our Evaluation  We received oral comments on a draft of this briefing from VA officials, including the  Deputy Assistant Secretary for Congressional and Legislative Affairs and the Assistant  Secretary for Information and Technology. In the comments, the Deputy Assistant  Secretary stated that the department was not in a position to concur or not concur with  our recommendations but planned to provide formal comments on our final report. The  officials provided additional clarification on why the department experienced delays in  data conversion. Specifically, they noted that, consistent with Agile practices, the  department reprioritized work and adapted the system to add selected functionality, such  as the 2010 housing rate adjustments. They added that the Joint Executive Board had  made this decision to ensure that claims examiners would have the most recent rate to  process benefits for the fall 2010 enrollment season. Additionally, the department  recognized lessons learned with the Agile approach, and it intends to incorporate them in  future development work. The officials provided other technical comments, which we have  incorporated as appropriate.
In further comments, the Assistant Secretary for Information and Technology emphasized  that using Agile system development for this initiative allowed the department to provide  significant system functionality incrementally that had far exceeded its past IT initiatives.  Specifically, he noted that the project had delivered working software close to schedule  and had been more successful than past system development efforts.
section_title: Sprint. Each team works in iterations that typically last 2 to 4 weeks; these blocks of time are known as sprints. During a sprint, each Scrum team creates a potentially shippable product (for example, working and tested software). These products are developed based on the user stories in the product backlog that are prioritized by the product owner and team. Each user story is assigned a level of effort, called story points. Story points are used as a relative unit of measure to communicate complexity and progress between the business and development sides of the project. Each sprint builds on the previous sprint to generate a working system. After a predetermined number of sprints, a release of the system goes into production.
section_title: Sprint review. After each sprint, teams demonstrate completed work and discuss work that was not finished with stakeholders. They also identify any problems that were encountered in completing the work. Feedback and priority is solicited from stakeholders so that it can be incorporated into future sprints.
