Army Networks: Opportunities Exist to Better Utilize Results from Network Integration Evaluations
Released: 2013-08-22T00:00:00


Highlights: section_title: Why GAO Did This Study
paragraphs: In 2011, the Army began a major undertaking to modernize its tactical network to improve communication and provide needed information to soldiers on the battlefield. The Army has identified the network as its number one modernization priority requiring approximately $3 billion per year indefinitely. NIEs provide semi-annual assessments of newly developed systems. Given the importance of the network, GAO was asked to examine elements of the process the Army is using to acquire network capabilities. This report examines (1) the results of the NIEs conducted to date and the extent to which the Army has procured and fielded network solutions, and (2) Army actions to enhance the NIE process. To conduct this work, GAO analyzed key documents, observed testing activities, and interviewed acquisition and testing officials.

section_title: What GAO Found
paragraphs: Since 2011, the Army has conducted five Network Integration Evaluations (NIE), which have provided extensive information and insights into current network capabilities and potential solutions to fill network capability gaps. According to senior Department of Defense (DOD) test officials, the NIE objective to test and evaluate network components together in a combined event is sound, as is the opportunity to reduce overall test and evaluation costs by combining test events. Further, the NIEs offer the opportunity for a more comprehensive evaluation of the broader network instead of piecemeal evaluation of individual network components. However, the Army is not taking full advantage of the potential knowledge that could be gained from the NIEs, and some resulting Army decisions are at odds with knowledge accumulated during the NIEs. For example, despite poor results in developmental testing, the Army moved forward to operational testing for several systems during the NIEs and they demonstrated similarly poor results. Yet the Army plans to buy and field several of these systems. Doing so increases the risk of poor performance in the field and the need to correct and modify deployed equipment. On the other hand, the Army has evaluated many emerging network capabilities--with generally favorable results--but has bought very few of them, in large part because it did not have a strategy to buy these promising technologies. Army officials have stated that the success of network modernization depends heavily on industry involvement but, with few purchases, it is unclear whether industry will remain interested. Finally, the Army has not yet developed metrics to determine how network performance has improved over time, as GAO recommended in an earlier report.

The Army has several actions under way or planned to enhance the NIE process and has further opportunities to collaborate with the test community. The Army has identified issues in the NIE process and its network modernization strategy that were causing inefficiencies or less-than-optimal results and has begun implementing actions to mitigate some of those issues. For example, the Army has begun performing technology evaluations, and integration of vendor systems in a lab environment to weed out immature systems before they get to the NIE. The Army has also developed a strategy and has an acquisition plan to address requirements, funding, and competition issues that will help enable it to buy emerging capabilities rapidly. However, the Army will need to validate the new strategy and plan and provide results to industry, which could help to manage industry expectations about how many of and how quickly it can buy these capabilities. DOD has started to identify and evaluate network metrics and to re-focus NIEs to gather additional data and insights. Taking these actions will ultimately allow the periodic review and evaluation of the actual effectiveness of network capabilities and the likely effectiveness of proposed investments. The test community has worked closely with the Army on the NIEs but has also voiced various concerns about the NIEs including their being a schedule-driven event. Tension between the acquisition and test communities has been long-standing. Additional opportunities exist for Army leadership and the test community to work together to further improve NIE execution and results and to reduce tensions between the two communities. A good starting point for the Army would be to take a fresh look at the test community observations and recommendations from previous NIEs.

section_title: What GAO Recommends
paragraphs: To improve outcomes for the Army’s network modernization strategy, GAO recommends that the Secretary of Defense direct the Army to (1) require successful developmental testing before moving to operational testing at an NIE, (2) correct issues identified during testing at NIEs prior to buying and fielding systems, (3) provide results to industry on Army’s efforts to rapidly acquire emerging capabilities, and (4) pursue additional opportunities for collaboration with the test community on the NIEs. DOD agreed with the recommendations to varying degrees, but generally did not offer specific actions to address them. GAO believes all recommendations remain valid.

section_title: Letter
paragraphs: In 2011, the Army began a major undertaking to modernize its tactical  network—at an estimated cost of about $3 billion per year indefinitely—to  improve communication and other capabilities and to provide needed  information to soldiers and commanders on the battlefield. The Army has  identified this network as its number one modernization priority. For  nearly 20 years, the Army has had limited success in developing its  information network of sensors, software, and radios to give soldiers and  commanders exact information when they need it, in any environment,  and thus improve situational awareness and decision making in combat.  To achieve this goal, the Army is implementing a new agile process,  which would take advantage of emerging networking solutions to keep  better pace with technology development and deploy selected systems to  the field much faster than previously possible. One key component of this  process is the Network Integration Evaluations (NIE), which are  assessments of newly developed systems held twice a year. The systems  are included in brigade level military exercises, which help Army senior  leaders decide whether the Army should field new systems.

Capability gaps are identified unfulfilled capability needs. new systems in an environment that models actual battle, resulting in  recommendations by soldier and system evaluators on whether to field,  continue to develop, or discontinue evaluation of these systems.

Because of the network’s importance, the ambitious nature of the current  network modernization strategy, and the department’s history with system  acquisitions over the past decade, you asked us to examine elements of  the new process the Army is using to acquire network capabilities. We will  address issues related to the NIE process, evaluation of new and current  network capabilities, and current plans for major network acquisition  programs in phases. In our first report, we addressed issues related to the  Army’s agile process. In this report, we examine the Army’s NIEs, a key  enabler of the agile process. Specifically, we evaluated (1) the results of  the NIEs conducted to date and to what extent the Army has procured  and fielded proposed network solutions; and (2) Army actions and  additional opportunities to enhance the NIE process.

To conduct this work, we used DOD policies and acquisition best  practices as a guide as we evaluated the Army’s approach to the NIEs  and their contributions to modernizing its tactical network. We observed  testing, visited laboratory facilities, interviewed acquisition and test  officials, and analyzed key documentation. A detailed description of our  scope and methodology is included in appendix I.

We conducted this performance audit from September 2012 to August  2013 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.
subsections: section_title: Background
paragraphs: As the Army transitions away from major wartime operations, it faces  fiscal constraints and a complex and growing array of security challenges.  The Army will be smaller and senior leaders recognize that the core of a  smaller yet still highly capable force is having a capable tactical  information network.

Over the last decade, the Army focused most of its decisions to field  network improvements on supporting operations in Iraq and Afghanistan,  an effort that was both expensive and time consuming. The Army did not  synchronize the development and fielding efforts for network  technologies. Funding and time lines for network-related programs were  rarely, if ever, aligned. The Army fielded capabilities in a piecemeal  fashion and the user in the field was largely responsible for integrating  them with existing technology.

In December 2011, Army leaders finalized the Network-enabled Mission  Command Initial Capabilities Document, a central document that  describes the essential network capabilities required by the Army as well  as scores of capability gaps. These capabilities support an Army mission  command capability defined by a network of command posts, aerial and  ground platforms, manned and unmanned sensors, and dismounted  soldiers linked by an integrated suite of mission command systems. A  robust transport layer capable of delivering voice, data, imagery, and  video to the tactical edge (i.e., the forward battle lines) connects these  systems.

To achieve the objectives of its network modernization strategy, the Army  is changing the way it develops, evaluates, tests, and delivers networked  capability to its operating forces, using an approach called capability set  management. A capability set is a suite of network components,  associated equipment, and software that provides an integrated network  capability. A requirement is an established need justifying the allocation  of resources to achieve a capability to accomplish military objectives.  Instead of developing an ultimate capability and buying enough to cover  the entire force, the Army plans to buy only what is currently available,  feasible, and needed for units preparing to deploy. Every year, the Army  will integrate another capability set that reflects changes or advances in  technology since the previous set. To support this approach, the Army is  implementing a new agile process that identifies capability gaps and  solicits solutions from industry and government to evaluate during the  NIEs.

NIEs are a significant investment. Since 2011, the Army has conducted  five of them, and has projected the cumulative cost of the events at $791  million. The Army conducts NIEs twice a year. Each NIE typically  involves around 3,800 soldiers and 1,000 vehicles, and up to 12,000  square kilometers of territory, and approximately 6 weeks in duration. The  two categories of the key participating systems during the NIEs are  Systems under Test (SUT) and Systems under Evaluation (SUE), and  each is subject to differing levels of scrutiny.

SUTs are from an ongoing acquisition program (sometimes referred to  as a program of record) that are formally determined to be ready for  operational testing in order to inform an acquisition decision. This operational testing is subject to review and is conducted with the  production or production-like system in realistic operational  environments, with users that are representative of those expected to  operate, maintain, and support the system when fielded or deployed.

SUEs are provided by either industry or the government. They are  either (1) developing capabilities with sufficient technology,  integration, and manufacturing maturity levels to warrant NIE  participation; or (2) emerging capabilities that are seen as next  generation war-fighting technologies that have the potential to fill a  known gap or improve current capabilities. SUEs are not subject to  formal test readiness reviews, nor the same level of testing as the  SUTs. SUEs are operationally demonstrated and receive a qualitative  user evaluation, but are not operationally tested and are not the  subject of a formal test report (as SUTs are).

Aside from their role in the agile process, NIEs also provide the Army with  opportunities for integration, training, and evaluation that leads to  doctrine, organization, training, materiel, leadership and education,  personnel, and facilities recommendations; and the refinement of tactics,  techniques, and procedures related to the systems tested.

The Army believes that traditional test and evaluation processes  frequently result in fielding outdated technologies and expects to improve  on those processes through the NIEs. The Army’s test community  members, including the Brigade Modernization Command (BMC) and the  Army Test and Evaluation Command (ATEC), conduct the testing during  the NIEs. The BMC is a headquarters organization within the Training and  Doctrine Command. It has an attached operational 3,800-soldier brigade  combat team dedicated to testing during the NIEs. BMC soldiers use  systems during the NIE in simulated combat scenarios for testing and  evaluation purposes, resulting in qualitative evaluations based on their  observations. The BMC also recommends whether to field, continue  developing, or stop developing each solution and to improve the  integration of capabilities into deploying brigades. ATEC has overall  responsibility for the planning, conduct, and evaluation of all Army  developmental and operational testing. ATEC also produces a qualitative  assessment of the overall performance of the current capability set of  network equipment.

Two test offices within the Office of the Secretary of Defense that help  inform Defense Acquisition Executive decisions also provide oversight on  testing related to major defense acquisition programs. The Director,  Operational Test and Evaluation (DOT&E) provides oversight of  operational testing and evaluation for SUTs. The Deputy Assistant  Secretary of Defense for Developmental Test and Evaluation (DT&E)  provides oversight of developmental testing that precedes operational  testing of SUTs. DOT&E and DT&E roles are limited to the SUTs selected  for operational testing during the NIEs.

Test and evaluation is a fundamental aspect of defense acquisition. DOD,  under its Defense Acquisition System, requires the integration of test and  evaluation throughout the defense acquisition process to provide  essential information to decision makers; assess attainment of technical  performance parameters; and determine whether systems are  operationally effective, suitable, survivable, and safe for intended use.  Testers generally characterize test and evaluation activities as either  developmental or operational. Developmental testing is a generic term  encompassing modeling and simulation and engineering type tests that  are used to verify that design risks are minimized, that safety of the  system is certified, that achievement of system technical performance is  substantiated, and that readiness for operational test and evaluation is  certified. The intent of developmental testing is to demonstrate the  maturity of a design and to discover and fix design and performance  problems before a system enters production.

Operational testing is a field test of a system or item under realistic  operational conditions with users who represent those expected to  operate and maintain the system when it is fielded or deployed. Specific  operational tests include limited user tests, initial operational tests, and  customer tests. Before operational tests occur for major acquisition  programs, DT&E completes an independent Assessment of Operational  Test Readiness. Each Assessment of Operational Test Readiness  considers the risks associated with the system’s ability to meet  operational suitability and effectiveness goals. This assessment is based  on capabilities demonstrated in developmental testing. The Defense or  Component Acquisition Executive considers the results of the  Assessment of Operational Test Readiness, among other inputs, in  making decisions on a major acquisition program proceeding to  operational testing.

section_title: Army Not Taking Full Advantage of Potential Knowledge from NIEs
paragraphs: The Army has made steady improvements in the NIE process since its  inception and the evaluations continue to give the Army useful information  and helpful insights into current and emerging networking capabilities.  However, some resulting Army decisions are at odds with knowledge  produced during the NIEs. Most importantly, despite poor operational test  results for a number of SUTs during the NIEs, the Army has sought  approval to buy additional quantities and field several major networking  systems. While many of the SUEs received favorable reviews, the Army  lacked a strategy that addresses a number of procurement barriers—such  as funding availability and requirements—when it began the NIE process,  which precluded rapid procurement of successful SUEs. Additionally, as  we reported previously, the Army has not yet tapped into the potential to  use the NIE to gain insight into the effectiveness and performance of the  overall tactical network.
subsections: section_title: NIEs Provide Several Advantages and Produce Volumes of Potentially Useful Information
paragraphs: To date, the Army has conducted five NIEs, costing an average of $158  million to plan and execute. Through those five NIEs, the Army has  operationally tested 19 SUTs and evaluated over 120 SUEs.

NIEs have helped the Army in a number of ways. The NIEs allowed the  Army to  formulate a network architecture baseline that will serve as the  foundation upon which the Army plans to add networking capabilities  in the future; evaluate industry-developed systems that may help address Army- identified capability gaps in the future; integrate the new capability sets into operational units and to create  new tactics, techniques, and procedures for using the new systems in  operations; and provide soldiers with an opportunity to both provide input into the  designs of networking systems and to integrate the systems before  the Army fields them to operational brigades.

According to Army officials, testing during each NIE generates a large  volume of potentially useful information. There are detailed operational  test and evaluation reports for each of the SUTs, user evaluations for  each of the SUEs, an integrated network assessment of the current  capability set, and general observations on the NIE event itself.

The DOT&E has reported observations of the NIEs in its fiscal years 2011  and 2012 annual reports, including an overall assessment, operational  scenarios and test design, threat information operations, and logistics.  According to DOT&E, the intended NIE objective to test and evaluate  network components together in a combined event is sound, as is the  opportunity to reduce overall test and evaluation costs by combining test  events. NIEs also offer the opportunity for a more comprehensive  evaluation of a mission command network instead of piecemeal  evaluation of individual network components. In addition, the DOT&E  generally reported overall improvements in the execution of the NIEs,  realistic and well-designed operational scenarios, and improvements in  threat information operations.

ATEC, in addition to preparing operational test reports for specific  systems, also prepares an integrated network assessment after each  NIE. The reports attempt to characterize how well the current capability  set performed with respect to several essential capabilities the Army  needs for improved mission command. Based on the performance  characterizations presented in the available reports for all NIEs, it  appears the Army is making progress in improving its networking  capabilities. For instance, the integrated network assessments for NIEs  12.2 and 13.1 cited improvements in an essential capability called  network operations. These reports also showed improvements in the  common operating picture, which is a capability that enables the receipt  and dissemination of essential information to higher echelon command  posts. As the Army has modified the reports to improve how they present  both capability set performance and essential capabilities, the reports  have become tools that are more useful for decision makers.

section_title: Army Accepting Risk by Buying and Fielding Systems with Poor Operational Test Results During the NIEs
paragraphs: Four SUTs that the Army plans to buy and field as part of capability set  13—Warfighter Information Network-Tactical (WIN-T) Increment 2, Joint  Tactical Radio System Manpack Radio, Joint Tactical Radio System  Rifleman Radio, and Nett Warrior—have demonstrated continued poor  performance and/or reliability in both developmental tests before NIEs  and operational tests during the NIEs. According to the DOT&E, system  development best practices dictate that a system should not proceed to  operational testing until it has completed developmental testing and  corrected any identified problems. To address these problems, the Army  has taken steps to implement design changes and schedule additional  testing to verify performance after it has implemented those changes.  However, in doing so, the Army faces the risk of making system design  changes during the production phase or fielding systems with less than  required performance or reliability.

Two of these SUTs performed poorly during developmental testing.  Developmental testers, through their Assessment of Operational Test  Readiness reports, recommended that the Manpack Radio and the  Rifleman Radio not proceed into operational testing. Despite these  recommendations, the Army proceeded with initial operational testing for  these systems during NIEs while reclassifying the participation of other  systems as either limited user tests or customer tests. The outcomes  were predictably poor, according to DOT&E. See table 1 for operational  test results from ATEC and DOT&E reports.

In its 2012 annual report, DOT&E pointed out that proceeding to  operational testing only confirmed the deficiencies identified in  developmental testing. For example, the WIN-T Increment 2 system’s  reliability was troublesome enough in a limited user test to warrant a  reduction in the reliability requirement. However, WIN-T Increment 2 was  unable to meet the reduced requirement. The Rifleman Radio also  demonstrated poor reliability during developmental testing in 2011 and  even worse reliability in operational testing due to the enhanced stress of  an operational environment. The DOT&E stated in its 2012 annual report  that, according to system development best practices, the Army should  not proceed to an Initial Operational Test and Evaluation with a system  until it has completed developmental testing and the program has  corrected any identified problems. Otherwise, the Army may conduct  costly operational tests that simply confirm developmental testing  conclusions about poor system performance and reliability rather than  taking action to fix system shortfalls. Further, DOT&E’s 2012 annual  report was critical of the Army’s NIE schedule-driven approach, which  elevates meeting a schedule above adequately preparing a system to  achieve success in operational testing. An event-driven approach,  conversely, would allow systems to participate in a test event after the  systems have satisfied certain criteria. Under the Army’s schedule-driven  approach, the NIEs are held twice a year and SUTs must align their  operational testing to coincide with the next available NIE. An event  driven-approach—versus a schedule-driven approach—is the preferred  method of test scheduling. Using a schedule-driven approach can result  in fielding systems that do not provide adequate utility for soldiers and  require costly and time-consuming modification in theater.

section_title: Army Working to Address Performance and Reliability Issues Identified During NIE
paragraphs: In light of poor operational test results during previous NIEs, the Army  now must pay for and conduct additional, unanticipated, tests to improve  system performance and reliability. The extent to which the additional  tests corrected all of the identified problems is unknown at this time as the  Army awaits the results of the operational testing conducted at the most  recent NIE. Ideally, the Army would demonstrate greater levels of  operational effectiveness and suitability prior to making production and  fielding decisions. Both GAO and DOT&E have acknowledged the risks of  proceeding through testing, and to procurement, with systems that  perform poorly. Such systems often require design changes that  frequently happen when systems are already in production, which can be  more costly and technically challenging. Table 2 summarizes the  additional activities required of selected systems.

In addition to the unplanned testing summarized in Table 2 above,  several systems have operational test and evaluation events scheduled.  See table 3.

Despite the poor test results and unplanned activities intended to improve  SUT performance, the Army has begun fielding SUTs for capability set  13, including WIN-T Increment 2, Joint Tactical Radio System (JTRS)  Manpack radio, Rifleman Radio, and Nett Warrior. Without disputing the  test findings and their implications, Army leadership indicates that this  equipment addresses critical capability shortfalls and operational needs  by providing some level of capability that is otherwise unavailable. For  example, most deployed units previously had no or very limited  capabilities other than voice communications. Consequently, the Army  believes it is urgent to modernize deploying units as quickly as possible,  with the equipment in capability set 13.

The Army’s approach carries risk. DOT&E has indicated that the principal  way of operating a less reliable system is to invest more in recurring  maintenance, which will enable the system to function, but will add to the  program’s life-cycle costs and increase its logistical support needs. As a  result, the Army will likely have to work with a system that is less reliable  than originally envisioned, and develop a new life-cycle cost estimate that  reflects the added costs associated with the increased contractor support  to keep this less reliable system operating. In addition, ATEC officials  state that the negative impact of an individual system falling short of its  reliability target is magnified in the capability set. This approach can result  in fielded systems that do not provide adequate utility for soldiers and  require costly and time-consuming modification in theater as well as  additional testing. Our past work as well as reports from DOT&E and  DT&E have all found benefits from adequate developmental testing prior  to fielding to prove system performance.

section_title: Army Buying Few Systems under Evaluation, Despite Positive Soldier Feedback
paragraphs: Since the first NIE in 2011, the Army has evaluated more than 120 SUEs  from both industry and government, many of which have received positive  reviews and recommendations for fielding from the soldiers. However, the  Army has been unable to buy many of these systems because it did not  have a strategy in place to rapidly buy promising technologies. Army  officials explained that existing DOD acquisition processes would not  allow the Army to quickly acquire SUEs that could immediately address  networking capability gaps. Even so, Army officials did not develop  alternative acquisition approaches before they began the NIE process. It  is unclear how long industry will continue to participate in the NIEs if the  Army is unable to begin buying systems. As discussed later in this report,  the Army has now developed new approaches to address barriers to its  ability to quickly buy and field SUEs that have successful demonstrations  during the NIEs.

Many SUEs have received positive reviews from soldiers at the NIEs— about five out of every six SUEs were recommended for fielding, field and  continue development, or potential for follow-on assessment. Table 4  shows the range of soldiers’ recommendations.

To date, the Army has decided to buy only three SUEs—a company  command post, which is a collection of capabilities that enhances a  company commanders’ ability to plan, execute, and monitor operations; a  touch screen-based mission command planning tool; and an antenna  mast. The Army will field only one of these systems in capability set 13— the company command post. While Army officials tell us they would like to  buy more systems, a number of factors—such as available funds,  deployment schedules, system maturity, and requirements—determine  which systems they can buy and when they can buy them. Because it did  not have a strategy during the NIEs to address these factors, the Army  has been limited in its ability to buy successfully demonstrated SUEs.

The Army expects industry participants to fund fully their own involvement  and initial participation in the process and NIEs, which can be a costly  endeavor. Army officials have said it can cost up to $250,000 for an  interested contractor to provide a whitepaper for consideration. These  whitepapers, which interested contractors submit to the Army in response  to a sources sought notice, are the industry contractor’s first opportunity  to explain both their system and how it addresses a particular capability  gap. The Army releases a sources sought notice to industry to solicit  candidate commercial solutions for network/non-network capability gaps  and the notice informs potential responders of evaluation criteria and  subsequent NIE participation criteria. Participation in later phases of the  agile process, and ultimately the participation in a NIE can cost the  contractor an estimated million dollars, depending on the system the  Army is evaluating. Because of the limited number of successfully  demonstrated SUEs that the Army has purchased to date, and the cost  associated with industry participation, there is concern that industry may  lose interest. This could be especially problematic for the Army’s agile  process which, according to the Army, is heavily dependent on industry  participation for success. Army officials remain confident in the continued  support of industry, but the depth and longevity of this support is unclear  at this time.

section_title: Army Not Using NIE to Evaluate Overall Network Performance and Effectiveness of Investments
paragraphs: While the NIEs are a good source of knowledge for the tactical network  as a whole, the Army has not yet tapped into that potential. In January  2013, we reported the Army had not yet set up testing and associated  metrics to determine how network performance has improved over time,which limited the evaluation of the cost-effectiveness of its network  investments. After completing each NIE, ATEC has provided an  integrated network assessment of how well the current capability set  enables the execution of the mission command essential capabilities.  This qualitative assessment includes only the impact of the current  capability set—and not the entire network—on the essential capabilities  and does not attempt to evaluate the cost-effectiveness of the current  capability set. The Army and DOD consider the fielding of capability set  13 as the initial output from the Army’s network modernization portfolio,  but the Army has yet to define fully outcome-based performance  measures to evaluate the actual contributions of the capability set.  Establishing outcome-based performance measures will allow the Army  and DOD to assess progress of network development and fielding and be  in a position to determine the cost-effectiveness of their investments in  capability set 13. We recommended that, among other things, the  Secretary of Defense direct the Secretary of the Army to define an  appropriate set of quantifiable outcome-based performance measures to  evaluate the actual contributions of capability set 13 and future  components under the network portfolio. As discussed later in this report,  DOD has started to develop metrics in response to our earlier  recommendation.

section_title: Army Actions and Additional Opportunities to Enhance the NIE Process
paragraphs: The Army is taking action to correct inefficiencies and other issues based  on lessons learned from previous NIEs. The Army is also planning to  address potential barriers to rapid procurement of successful SUEs, and  DOD has started the process to implement our earlier recommendations  on network metrics. Many of the initiatives are in the early stages of  implementation so outcomes are not certain. The Army also has an  opportunity to work more closely with the test community to further  improve NIE execution and results.
subsections: section_title: Army Is Implementing Corrective Actions to Improve NIE Process and Network Modernization
paragraphs: The Army has identified inefficiencies or less-than-optimal results in its  network modernization and the NIE process and has begun implementing  corrective actions to mitigate some of them. Table 5 shows some of the  major issues identified by the Army and the corrective actions, which are  in early stages of implementation.

The Army’s lab-based risk reduction, currently under way, seeks to  address concerns over too many immature SUEs sent to past NIEs.  Through this initiative, the Army performs technology evaluations,  assessments, and integration of vendor systems. Officials test systems  individually and as part of an integrated network so that problems can be  identified before proceeding to an NIE. In some cases, Army officials  identify changes for these systems to increase the likelihood of their  success during an NIE, while it drops others when they do not perform  well enough in lab testing. Since this effort began, the Army has reduced  the number of systems it evaluates during the NIEs, indicating the Army  may be making soldiers’ NIE workloads more manageable.

While Army officials acknowledge that lab-based risk reduction does not  eliminate all risks, this early evaluation of new systems seems to address  some concerns. It may reduce the number of immature systems in the  NIE, which could help the Army train soldiers for the new systems.  Sending only mature SUEs that have gone through integration testing to  NIEs could also help avoid certain test costs.

Additionally, to reduce costs, improve the results of NIEs, and better  support rapid fielding of new network capabilities, the test community has  reported on several issues requiring corrective action by the Army.  Additionally, the testers have also taken actions to help reduce  redundancies in test data collection processes, among other things.  Implementation of these corrective actions, which testers identified during  earlier NIEs, could help prevent negative impacts to NIE testing and  modernization. Table 6 describes a number of major issues identified by  the test community and corrective actions, which are in early stages of  implementation.

Most of the corrective actions to address test community concerns are in  early stages of implementation. Below are additional details about the  status of a few of the key initiatives.

Army test officials anticipate avoiding $86 million in NIE costs due to  implementation of a dozen different efficiency initiatives, including making  NIEs more efficient by eliminating duplicative surveys, consolidating data  systems, refining SUE test data delivery processes, reducing reliance on  contractor data collectors by using military personnel more, and  automating data collection. Additionally, BMC officials indicated they  intend to incorporate additional testing and reduce the number of soldiers  involved in future NIEs to help reduce testing costs. Over time, as the  Army conducts NIEs more efficiently, it plans to reduce the number of test  personnel, realize commensurate salary savings, and reduce engineering  expenses.

Training and guidance for soldiers using new systems during the NIE is  another area receiving attention from the test community and the Army.  Army test officials reported that there were gaps in soldier training for the  SUEs to be evaluated in NIE 13.1. The training issues, in turn, affected  the usefulness of the subsequent system evaluations. DT&E officials also  expressed concerns about soldier training, and said problems exist in the  rehearsal phase of the NIE process. Brigade Combat Team officials said  they have also experienced a lack of training resources as they prepare  to deploy overseas. According to Army officials, a lack of complete  training information, tactics, techniques, and procedures is hampering  soldier training on new network systems. That experience was somewhat  mitigated, however, by help from soldiers who had used these systems  during earlier NIE events. It will be important for the Army to resolve  training issues before operational testers qualify systems as fully suitable  for combat use following operational testing. Given that operations and  support can often comprise about two-thirds of life-cycle costs, a good  understanding of these requirements and costs will be necessary for the  Army to make well-informed investment decisions for new equipment.

Assessing and using lessons learned from experience can help in  planning and implementing future activities. The Army’s efforts to reduce  costs and implement corrective actions may take several years; therefore,  a continued focus on making NIE processes more efficient and effective,  as well as documenting the results of corrective actions would better  support the Army’s business case for conducting future NIEs.

section_title: Army Efforts to Reduce Barriers to Rapid Procurement of Successful Emerging Technologies
paragraphs: The Army is developing a two-pronged approach to address barriers to its  ability to quickly buy and field SUEs that have successful demonstrations  during the NIEs. According to Army officials, these barriers included a  lack of well-defined requirements for the network system (instead of the  more general capability gaps); a lack of funding; and lengthy time frames  needed to complete the competitive procurement process. The Army  found that the processes for translating capability gaps into requirements,  identifying specific funding, and completing a competitive procurement  can be very time consuming and challenging.

The Army is now developing a strategy to address these barriers. After  the NIE, if the Army decides to buy and field a SUE, the Army plans to  align that capability with a suitable existing requirement within an ongoing  program of record. The selected program manager would then identify  buying options for the capability, including the feasibility of using an  existing contract, and would determine whether (1) funding is available,  (2) the Army should identify the capability as an unfunded requirement, or  (3) the Army needs an above-threshold reprogramming action. The  program manager would also determine if the Army can buy and field the  capability in the capability set or identify what capability is achievable.  Army officials plan to implement this new strategy in the coming months.

In cases where the Army cannot align the successful SUE with an  existing program of record, it could develop a new requirement for the  system. Army officials have indicated that in a small number of cases, the  Army could utilize a directed requirement. The Army generally develops  and approves directed requirements to fill urgent needs that the Army  believes should be fielded as soon as possible. This allows for essentially  bypassing the regular requirements processes, which require additional  time to complete.

In addition to this strategy, the Army has developed a new NIE acquisition  plan that features an alternative means to buy successful SUEs rapidly.

Under this new plan, the Army is using a combined sources sought notice  and a request for proposals approach to better shape requirements and  allow for buying SUEs in less time than under normal acquisition  processes. With two NIEs per year, the Army will continue to use a  sources sought notice to solicit government and industry solutions to  broadly defined capability gaps and will assess those solutions during a  NIE. Then, the Army will use lessons learned and soldier feedback from  the first NIE to validate and refine the requirement and issue a request for  proposal for participation in a future NIE. Using a request for proposal  differs from using sources sought notices because the request for  proposals approach culminates in the award of indefinite-delivery,  indefinite-quantity contracts for industry SUEs to participate in a future  NIE. Using an indefinite-delivery, indefinite-quantity contract allows the  Army to place production orders for industry SUEs following the NIE. The  Army released the first request for proposals supporting a NIE on  December 20, 2012, to solicit vehicle tactical routers for NIE 14.1. Vehicle  tactical routers would allow users and systems located nearby to access  networks securely.

For SUEs that already have a defined requirement, the Army plans to  issue a request for proposals for participation in one NIE, without using a  sources sought notice first. However, Army officials concede that a  defined requirement is not usually available prior to the NIE. In those  cases, the Army plans to continue issuing sources sought notices for  industry proposed solutions that the Army will evaluate during a NIE, as a  precursor to issuance of a request for proposals in the future.

The Army expects to comply with current DOD acquisition policy when it  decides to buy systems that proceed through the agile process. However,  the Army may propose changes to existing policy and processes that  inhibit realization of the full benefits of the agile process.

As the Army implements this strategy over the coming months, it will be  important to gather information on how well the strategy works and how  rapidly the Army can procure and field a SUE after its successful  demonstration during an NIE. At the same time, the Army will be in a  better position to determine how much of its constrained budget it can  devote to the procurement of SUEs. As recommended under internal  control standards, it will be important for the Army to establish specific  measures and indicators to monitor its performance and validate the  propriety and integrity of those performance measures and indicators.This type of information—on how many SUEs the Army can buy and how  rapidly—would be helpful for industry as it makes decisions on its future  participation in the NIE process.

section_title: DOD Has Begun to Define Network Outcome-based Performance Metrics
paragraphs: In our initial report on the Army’s tactical network, we concluded that it will  also be important for the Army to assess the cost effectiveness of   Moreover, to  individual initiatives before and during implementation.facilitate oversight, we concluded that it is important for the Army and  DOD to develop metrics to assess the actual contributions of the initial  capability set the Army will field in fiscal year 2013 and use the results to  inform future investments.

According to a key DOD oversight official reporting on Army networks to  the Under Secretary of Defense, Acquisition, Technology, and Logistics,  DOD has started work to define quantifiable outcome-based performance  measures for the Army tactical network. In addition, both DOD and Army  officials indicated they are planning to develop a preferred end-to-end  performance projection for the Army tactical communications network and  intend to quantify the performance needed in terms of voice, data, and so  forth, and by network tier, sector, and subnet. Officials plan to define  levels of performance for benign and conflict environments and the  waveforms and radios soldiers will need for each tier as well as their  specific performance characteristics. Although this effort is in its early  stages, this DOD oversight official stated that it is expected that the NIE  will generate data on performance of the network as a whole, which could  then be compared to the expected performance demand.

Separately, the Army is also beginning to prepare qualitative  assessments of the progress the Army is making in filling capability gaps  related to mission command essential capabilities. For example, ATEC  has prepared an integrated network assessment after each NIE, which  characterizes the level of capability achieved against the mission  command essential capabilities. In addition, the Army has prepared a  limited assessment of how capability set 13 will meet mission command  essential capabilities.

Once the performance measures are in place and the Army evaluates the  delivered capabilities against those measures, the Army will have the  tools to evaluate the progress it is making and make any necessary  adjustments to its investment strategy.

section_title: Opportunities for Additional Collaboration between Army and Test Community
paragraphs: The Army’s network strategy features a variety of different approaches to  testing and evaluation to accommodate the rapid pace of technology  change and to reduce the cost and time of acquisition. The Army has  worked closely with the test community to plan, conduct, and evaluate the  NIEs. Also, as mentioned earlier, the test community has taken a number  of actions to reduce the costs of planning and executing the NIEs. At the  same time, the test community has been meeting its responsibility to  objectively report on the tests and the results. However, test results for  several network systems at the NIEs that did not meet operational and  other requirements will result in added time and expense to address  identified issues. An inherent value of testing is pointing out key  performance, reliability, and other issues that need to be addressed as  soon and as economically as possible, but not after fielding. DOT&E has  stated that the schedule-driven nature of the NIEs contribute to systems  moving to testing before they have met certain criteria.

Tension between the acquisition and testing communities has been long- standing. In that regard, the Defense Acquisition Executive recently  chartered an independent team to assess concerns that the test  community’ approach to testing drives undue requirements, excessive  cost, and added schedule into programs and results in a state of tension  between program offices and the testing community.

One area the Defense Acquisition Executive assessment identified for  improvement was the relationship and interaction among the testing,  requirements, and program management communities. In that regard, the  memorandum reporting the results called attention to four specific issues  those communities need to address the need for closer coordination and cooperation among the  requirements, acquisition, and testing communities; need for well-defined testable requirements; alignment of acquisition strategies and test plans; and need to manage the tension between the communities.

Concurrently, a systematic review of recent programs by DOT&E and  DT&E examined the extent to which testing increases costs and delays  programs. The results of both efforts indicated that testing and test  requirements by themselves do not generally cause major program  delays or increase costs. In addition, the Defense Acquisition Executive  found no significant evidence that the testing community typically drives  unplanned requirements.

Further, according to the DOT&E fiscal year 2012 annual report, three  specific areas exist where increased test community interactions could  result in improved test outcomes, which can result in systems with  needed and useful combat capability being delivered to our forces more  quickly. These include developing mission-oriented metrics to evaluate each system within  the context within which it will operate; leveraging test and evaluation knowledge in setting requirements; and evaluating the multiple conditions in which the system is likely to be  operated.

Additional opportunities exist for leadership of the Army and the test  community to work together to further improve NIE execution and results.  A good starting point would be for the Army to consider addressing the  test community observations and recommendations from previous NIEs.  Those included the schedule driven nature of NIEs, the lack of well- defined network requirements, and the lack of realistic battlefield  maintenance and logistical support operations for SUTs during the NIEs.  The Army is not required to and has not directly responded to the test  community about its NIE observations and recommendations.  Nevertheless, per internal control standards, managers are to, among  other things, promptly evaluate findings from audits and other reviews,  including those showing deficiencies and recommendations reported by  auditors and others who evaluate agencies’ operations. In doing so, the  Army may not only improve NIE execution and results but also reduce the  tensions with the test community.

section_title: Conclusions
paragraphs: Within a sizable investment of an estimated $3 billion per year to  modernize its tactical network, the Army is investing over $150 million per  NIE to help ensure that those planned development and procurement  investments result in the expeditious delivery of increased capabilities to  the warfighter.

The main product of the NIEs is knowledge. The Army has not  consistently recognized, accepted, and acted upon the knowledge gained  from the NIEs. On the one hand, the Army’s fielding decisions to date  seem driven by a pre-determined schedule rather than operational test  results. Fielding individual systems that have done poorly during  operational tests carries risk of less than optimal performance with the  potential of costly fixes after fielding and increased operating and  sustainment costs. Moreover, performance and reliability issues of  individual systems could be magnified when these systems become part  of an integrated network. On the other hand, even with a new strategy for  procurement of emerging capabilities to fill capability gaps, the Army may  still face an expectation gap with industry. The current constrained budget  environment and the level of funding already allocated to ongoing network  acquisition programs, may leave little funding to procure new networking  technologies. Until it has clearly demonstrated the means to rapidly buy  and field emerging capabilities and provided this information to industry,  the Army may need to manage industry expectations of how many new  networking systems it can buy and how rapidly.

The Army has implemented some lessons learned from planning and  executing the NIEs. However, as part of a knowledge-based approach to  its broader network modernization strategy, the Army should also be open  to consideration of observations from all sources to improve process  efficiency and achieve improved outcomes. We believe that the Army can  and should collaborate more extensively with the test community on a  variety of issues that could improve NIE outcomes. For example, as part  of its responsibility to objectively conduct tests and report on their results,  the test community has provided reports, observations, and  recommendations before and following NIEs. To date, the Army has not  directly responded to the test community’s observations and  recommendations on the NIEs.

section_title: Recommendations for Executive Action
paragraphs: To improve outcomes for its entire network modernization strategy, we  recommend that the Secretary of Defense direct the Secretary of the  Army to take the following four actions:

Require that network systems from major defense acquisition  programs obtain a positive Assessment of Operational Test  Readiness (now called a Developmental Test and Evaluation  Assessment) recommendation before being scheduled for operational  testing during the NIE;

Correct network system performance and reliability issues identified  during the NIEs before moving to buy and field these systems;

Provide results to industry on the Army’s actual experience in buying  and fielding successfully demonstrated systems under evaluation and  the length of time it has taken to date; and

Collaborate with all network stakeholder organizations to identify and  correct issues that may result in improved network outcomes,  including addressing the observations and recommendations of the  test community related to the NIEs.

section_title: Agency Comments and Our Evaluation
paragraphs: DOD’s written response to this draft is reprinted in appendix II. DOD also  provided technical comments that were incorporated as appropriate.

DOD partially concurred with our recommendations that the Army (1)  require network systems obtain a positive Assessment of Operational  Test Readiness (now called a Developmental Test and Evaluation  Assessment) recommendation before being scheduled for operational  testing during the NIE and (2) correct network system performance and  reliability issues identified during the NIEs before moving to buy and field  these systems.  In both cases, DOD states that processes are already in  place to address these issues and that the recommendations as written  take flexibility away from the Department. We disagree. Our findings  indicate that DOD is not using its current processes effectively to evaluate  a system’s readiness to begin operational testing. While there may be  instances where the Army uses operational testing to obtain feedback on  system performance, DOD’s system development best practices dictate  that a system should not proceed to operational testing until it has  completed developmental testing and corrected any identified problems.

The NIEs are a good forum for the Army to generate knowledge on its  tactical network.  However, NIEs are a large investment and DOD and the  Army should strive to optimize their return on that investment.  Approving  network systems for operational testing at the NIEs after having poor  developmental test results may not be the best use of NIE resources  because of the strong correlation between poor developmental test  results and poor operational test results. Moreover, it is much more cost  effective to address performance and reliability issues as early as  possible in the system development cycle and well in advance of the  production and fielding phases.  As we note in the report, DOD and the  Army have been pursuing a schedule-based strategy for network  modernization rather than the preferred event-based strategy where  participation in a test event occurs after a system has satisfied certain  criteria.

DOD concurred with our recommendation that the Army provide results to  industry on how many successfully demonstrated systems under  evaluation have been procured to date and how long it has taken for the  procurements.  However, DOD did not offer specific steps it would take to  provide this information or a proposed timeframe.  Because of the  importance of continued industry participation in the development of the  Army network, we think that it is important for industry to have a clear  picture of the Army’s success in rapidly buying and fielded emerging  technologies.  Finally, DOD concurred with our recommendation that the  Army collaborate with all network stakeholder organizations to identify  and correct issues that may result in improved network outcomes,  including addressing the observations and recommendations of the test  community related to the NIEs.  DOD states that a collaborative  environment with all stakeholders will assist in identifying and correcting  issues and that the forum for doing so is the semiannual Network  Synchronization Working Group.  We agree that a collaborative  environment is important in responding to previous test community  observations and recommendations and would expect the Working Group  to address these issues.

section_title: Appendix I: Scope and Methodology
paragraphs: Our objectives were to evaluate (1) the results of the Network Integration  Evaluations (NIE) conducted to date and identify the extent to which the  Army has procured and fielded proposed network solutions; and (2) Army  actions and additional opportunities to enhance the NIE process. To  address these objectives, we interviewed officials from the Army’s System  of Systems Integration Directorate; the Deputy Chiefs of Staff, G-3/5/7  and G-8; the Army Brigade Modernization Command, and the Army Test  and Evaluation Command. We met with representatives of Army Brigade  Combat Teams preparing for deployment. We also interviewed officials  from the Deputy Assistant Secretary of Defense for Developmental Test  and Evaluation; the Director, Operational Test and Evaluation; and the  Office of the Under Secretary of Defense for Acquisition, Technology, and  Logistics. We visited the Lab Based Risk Reduction facility at Aberdeen  Proving Ground, Maryland and the NIE test site at White Sands Missile  Range, New Mexico to meet with soldiers and civilian officials conducting  testing.

To examine the results of NIEs conducted to date, we attended Network  Integration Evaluations and reviewed test reports from the Brigade  Modernization Command, U.S. Army Test and Evaluation Command, the  Director of Operational Test and Evaluation, and the Deputy Assistant  Secretary of Defense for Developmental Test and Evaluation. We  reviewed briefing presentations for Army leadership that discuss test  results and recommendations, and we toured lab facilities to understand  how the Army is validating and selecting technologies for network  evaluations. We reviewed Army programmatic and budget documentation  to understand cost projections for testing and procuring network  equipment under the new approach and we reviewed Army plans for  resourcing this approach.

To identify actions and opportunities to enhance the NIE process, we  interviewed Army officials to identify other networking challenges the  Army is addressing concurrent with implementation of the agile process.  We reviewed test results from both the Army and Department of Defense.  We reviewed Army documentation identifying cost avoidance  opportunities. We reviewed briefing information regarding lessons learned  from activities related to the NIE, such as the screening and lab testing of  candidate systems and soldier training. We spoke with officials at both  Army and Department of Defense knowledgeable of lessons learned for  the testing and fielding of new network capabilities.

We conducted this performance audit from September 2012 to August  2013 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.

Question-summary annotations: questions: question: What is the purpose of the Network Integration Evaluations conducted by the Army?
answer: Since 2011, the Army has conducted five Network Integration Evaluations (NIE), which have provided extensive information and insights into current network capabilities and potential solutions to fill network capability gaps.
child_questions: question: How sound is the NIE objective?
answer: According to senior Department of Defense (DOD) test officials, the NIE objective to test and evaluate network components together in a combined event is sound, as is the opportunity to reduce overall test and evaluation costs by combining test events. Further, the NIEs offer the opportunity for a more comprehensive evaluation of the broader network instead of piecemeal evaluation of individual network components.

question: To what extent are the NIEs being utilized to their full extent?
answer: However, the Army is not taking full advantage of the potential knowledge that could be gained from the NIEs, and some resulting Army decisions are at odds with knowledge accumulated during the NIEs. For example, despite poor results in developmental testing, the Army moved forward to operational testing for several systems during the NIEs and they demonstrated similarly poor results.
child_questions: question: What decision could exacerbate this problem?
answer: Yet the Army plans to buy and field several of these systems.
child_questions: question: What is the risk of such a plan?
answer: Doing so increases the risk of poor performance in the field and the need to correct and modify deployed equipment.

question: What has characterized the Army's relationship to emerging network capabilities thus far?
answer: On the other hand, the Army has evaluated many emerging network capabilities--with generally favorable results--but has bought very few of them, in large part because it did not have a strategy to buy these promising technologies.

question: What factor determines the success of network modernization?
answer: Army officials have stated that the success of network modernization depends heavily on industry involvement but, with few purchases, it is unclear whether industry will remain interested.

question: How well has Army evaluated network performance metrics?
answer: Finally, the Army has not yet developed metrics to determine how network performance has improved over time, as GAO recommended in an earlier report.

questions: question: How has the Army attempted to address the NIE process?
answer: The Army has several actions under way or planned to enhance the NIE process and has further opportunities to collaborate with the test community. The Army has identified issues in the NIE process and its network modernization strategy that were causing inefficiencies or less-than-optimal results and has begun implementing actions to mitigate some of those issues.
child_questions: question: What are some specific examples that illustrate the Army's efforts?
answer: For example, the Army has begun performing technology evaluations, and integration of vendor systems in a lab environment to weed out immature systems before they get to the NIE. The Army has also developed a strategy and has an acquisition plan to address requirements, funding, and competition issues that will help enable it to buy emerging capabilities rapidly.

question: Why does the Army need to validate their new strategy?
answer: However, the Army will need to validate the new strategy and plan and provide results to industry, which could help to manage industry expectations about how many of and how quickly it can buy these capabilities.
child_questions: question: How has it started to do so?
answer: DOD has started to identify and evaluate network metrics and to re-focus NIEs to gather additional data and insights.
child_questions: question: What is the purpose of the DOD's evaluation of the network metrics?
answer: Taking these actions will ultimately allow the periodic review and evaluation of the actual effectiveness of network capabilities and the likely effectiveness of proposed investments.

question: What concerns has the test community raised about this process?
answer: The test community has worked closely with the Army on the NIEs but has also voiced various concerns about the NIEs including their being a schedule-driven event. Tension between the acquisition and test communities has been long-standing.
child_questions: question: How can the Army improve these relationships?
answer: Additional opportunities exist for Army leadership and the test community to work together to further improve NIE execution and results and to reduce tensions between the two communities. A good starting point for the Army would be to take a fresh look at the test community observations and recommendations from previous NIEs.

questions: question: Why did the Army attempt to modernize their tactical network?
answer: In 2011, the Army began a major undertaking to modernize its tactical network to improve communication and provide needed information to soldiers on the battlefield.
child_questions: question: How does this network affect the Army monetarily?
answer: The Army has identified the network as its number one modernization priority requiring approximately $3 billion per year indefinitely.

question: Why did GAO examine the Army's network?
answer: Given the importance of the network, GAO was asked to examine elements of the process the Army is using to acquire network capabilities.
child_questions: question: What are the contents of GAO's report?
answer: This report examines (1) the results of the NIEs conducted to date and the extent to which the Army has procured and fielded network solutions, and (2) Army actions to enhance the NIE process.

question: How was this report conducted by GAO?
answer: To conduct this work, GAO analyzed key documents, observed testing activities, and interviewed acquisition and testing officials.

questions: question: What measures did GAO recommend in order to augment the Army's network modernization strategy?
answer: To improve outcomes for the Army’s network modernization strategy, GAO recommends that the Secretary of Defense direct the Army to (1) require successful developmental testing before moving to operational testing at an NIE, (2) correct issues identified during testing at NIEs prior to buying and fielding systems, (3) provide results to industry on Army’s efforts to rapidly acquire emerging capabilities, and (4) pursue additional opportunities for collaboration with the test community on the NIEs.
child_questions: question: How did the DOD respond to these recommendations?
answer: DOD agreed with the recommendations to varying degrees, but generally did not offer specific actions to address them.
child_questions: question: What is GAO's stance on this response?
answer: GAO believes all recommendations remain valid.
