CROSS REFERENCE TO RELATED APPLICATIONS  
       [0001]     The present application is related to co-pending U.S. patent application Ser. No. ______ (Client Docket No. LEDS.00133) entitled “TESTING PRACTICES ASSESSMENT PROCESS” filed even date herewith. The content of the above mentioned commonly assigned, co-pending U.S. Patent application is hereby incorporated herein by reference for all purposes. 
     
    
     BACKGROUND OF THE INVENTION  
       [0002]     1. Technical Field  
         [0003]     The present invention relates generally to computer software and, more particularly, to assessing testing practices used in optimizing software development.  
         [0004]     2. Description of Related Art  
         [0005]     Secure testing of software and project development can account for up to 40% to 50% of a project&#39;s total cost, time and resources. Furthermore, testing can mitigate project risks, ensure successful implementations and promote customer satisfaction. However, for many organizations, testing is not seen as a priority activity, with the majority of project funds spent on development and production support. Thus, many organizations, failing to realize the importance of testing, utilize poorly designed or ad hoc testing practices in measuring the maturity and quality of the software under development. Therefore, the organization lacks sufficient information to determine which areas to concentrate resources on in improving the software. Thus, unnecessary time and expense are expended in developing software due to poor testing practices which also leads to poor quality. Furthermore, many organizations may have a goal of achieving a certain project maturity level, but are unable to do so because of poor testing practices.  
         [0006]     Therefore, it is desirable to have a testing assessment method and system that allows an organization to determine weaknesses in its testing practices and software under development in order to focus resources in the proper area. Furthermore, it is desirable to have a visual representation that would effectively highlight the areas requiring improvement as well as providing the organization with a list of recommendations that would allow them to demonstrate improvement at a follow-up assessment.  
       SUMMARY OF THE INVENTION  
       [0007]     The present invention provides a method, system, and computer program product for analyzing project testing practices of an organization. In one embodiment, a consultant is provided with a set of documents utilized for initiating the testing practices assessment process as well as with a testing assessment questionnaire. The questions in the questionnaire are tailored to a select number of key focal areas and provide the consultant with a standardized set of questions leading to repeatability of the process and quantization of results and recommendations. The consultant is also provided with a spreadsheet for entering the consultant&#39;s observations and the organization&#39;s answers to the questionnaire. A graphical representation of maturity levels for a select number of sub-levels for at least one of the key focal areas is generated based on the consultant&#39;s entries in the spreadsheet.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0013]     With reference now to the figures, and in particular with reference to  FIG. 1 , a pictorial representation of a data processing system is depicted in which one embodiment of a testing assessment tool kit for assessing the project testing practices of an organization according to the present invention may be implemented. The Testing Practices Assessment Toolkit allows a consultant to analyze, using a process of the present invention, the testing procedures of a client organization to determine whether proper testing practices are being utilized to ensure the success of the organizations project. The Testing Practices Assessment Toolkit provides a consultant with tools that ensure when a subsequent assessment is performed, only the results may change—not the process. This toolkit: 
        Provides the questions for client interviews;     Provides a means of recording client answers and mapping them to the maturity levels;     Identifies best practices;     Provides checklists to analyse project testing documentation;     Provides a guideline for improvements over the short and long term;     Provides an objective, unbiased review of testing practices;     Provides consistency regardless of the consultant performing the assessment;     Provides consistency between the initial assessment and follow-up assessments.        
 
         [0022]     A personal computer  100  is depicted which includes a system unit  110 , a video display terminal  102 , a keyboard  104 , storage devices  105 , which may include floppy drives and other types of permanent and removable storage media, and a pointing device  106 , such as a mouse. Additional input devices may be included with personal computer  100 , as will be readily apparent to those of ordinary skill in the art.  
         [0023]     The personal computer  100  can be implemented using any suitable computer. Although the depicted representation shows a personal computer, other embodiments of the present invention may be implemented in other types of data processing systems, such as mainframes, workstations, network computers, Internet appliances, palm computers, etc.  
         [0024]     The system unit  110  comprises memory, a central processing unit, one or more I/O units, and the like. However, in the present invention, the system unit  110  preferably contains a speculative processor, either as the central processing unit (CPU) or as one of multiple CPUs present in the system unit.  
         [0025]     With reference now to  FIG. 2 , a block diagram of a data processing system in which the present invention may be implemented is illustrated. Data processing system  200  is an example of a computer such as that depicted in  FIG. 1 . A Testing Practices Assessment Tool Kit according to the present invention may be implemented on data processing system  200 . Data processing system  200  employs a peripheral component interconnect (PCI) local bus architecture. Although the depicted example employs a PCI bus, other bus architectures, such as Micro Channel and ISA, may be used. Processor  202  and main memory  204  are connected to PCI local bus  206  through PCI bridge  208 . PCI bridge  208  may also include an integrated memory controller and cache memory for processor  202 . Additional connections to PCI local bus  206  may be made through direct component interconnection or through add-in boards. In the depicted example, local area network (LAN) adapter  210 , SCSI host bus adapter  212 , and expansion bus interface  214  are connected to PCI local bus  206  by direct component connection. In contrast, audio adapter  216 , graphics adapter  218 , and audio/video adapter (A/V)  219  are connected to PCI local bus  206  by add-in boards inserted into expansion slots. Expansion bus interface  214  provides a connection for a keyboard and mouse adapter  220 , modem  222 , and additional memory  224 . In the depicted example, SCSI host bus adapter  212  provides a connection for hard disk drive  226 , tape drive  228 , CD-ROM drive  230 , and digital video disc read only memory drive (DVD-ROM)  232 . Typical PCI local bus implementations will support three or four PCI expansion slots or add-in connectors.  
         [0026]     An operating system runs on processor  202  and is used to coordinate and provide control of various components within data processing system  200  in  FIG. 2 . The operating system may be a commercially available operating system, such as Windows XP, which is available from Microsoft Corporation of Redmond, Wash. “Windows XP” is a trademark of Microsoft Corporation. An object oriented programming system, such as Java, may run in conjunction with the operating system, providing calls to the operating system from Java programs or applications executing on data processing system  200 . Instructions for the operating system, the object-oriented operating system, and applications or programs are located on a storage device, such as hard disk drive  226 , and may be loaded into main memory  204  for execution by processor  202 .  
         [0027]     Those of ordinary skill in the art will appreciate that the hardware in  FIG. 2  may vary depending on the implementation. For example, other peripheral devices, such as optical disk drives and the like, may be used in addition to or in place of the hardware depicted in  FIG. 2 . The depicted example is not meant to imply architectural limitations with respect to the present invention. For example, the processes of the present invention may be applied to multiprocessor data processing systems.  
         [0028]     With reference now to  FIG. 3 , a flow chart illustrating an exemplary process for analyzing an organizations testing practices as well as toolkit components to aid in that process is depicted in accordance with one embodiment of the present invention. This procedure for performing Testing Practices Assessments provides a consultant with a repeatable process that: 
        Identifies the strengths of the existing testing practices;     Identifies current and potential problems;     Identifies beneficial and achievable improvements;     Provides a guideline for achieving improvements over the short and long term.        
 
         [0033]     Testing consultants gather information on the current testing process through a structured questionnaire, interviews and review of project documentation. This information is analyzed, improvement opportunities are identified, and recommended solutions are presented to the client. This analysis is accomplished through a consultant&#39;s: 
        Understanding and evaluating the client&#39;s testing practices;     Understanding and evaluating the conformity of the testing team to best practices;     Assessing the quality of the work being produced;     Measuring the progress of the testing team against the schedule;     Mapping this information to best practices (gap analysis).        
 
         [0039]     Questionnaires and interviews are used to gather information. Questions are divided into key categories: Testing Organization, Testing Strategy, Test Planning, Testing Management, and Testing Environment and Tools. The assessment compares industry best practices against the current testing situation. The resulting gap analysis provides the basis for the recommendations. A final report provides a client with the assessment findings as well as strategic, tactical recommendations.  
         [0040]     Throughout this process the consultant management and Subject Matter Experts review and approve deliverables to ensure consistency, correctness, and fit to the original statement of work.  
         [0041]     The diagram illustrated in  FIG. 3  identifies the activities involved in the testing process assessment. To begin, a consultant gathers current testing practices documentation and procedures (step  302 ). This documentation and procedures includes toolkit documents  320 - 328  that are part of an assessment initiation  301  as well as a testing assessment questionnaire  332 . These documents that are part of the toolkit as well as other parts of the toolkit will be discussed in greater detail below.  
         [0042]     Once the consultant has gathered together the appropriate documentation and procedures, the consultant conducts interviews with members of the client organization (step  304 ). Next, the consultant analyzes the current situation and conducts gap analysis comparing the organizations practices against an industry standard best testing practices  334  and supplying answers to a testing assessment dashboard spreadsheet  336  (step  306 ). The testing assessment dashboard spreadsheet  336  will be discussed in greater detail below.  
         [0043]     The consultant then determines recommendations (step  308 ) based on the consultants experience in combination with the assessment process and toolkit of the present invention. A preliminary internal review may be performed if desired (step  309 ) and then the consultant creates a report  338 , presentation  340 , and implementation plan  342  (step  310 ). The report  338 , plan  340 , and presentation  342  are created using the toolkit thus ensuring a consistent format. Next, a final internal review may be performed (step  311 ) and then the findings are presented to the client (step  312 ).  
         [0044]     The toolkit inputs consist of a Testing Assessment Statement of Work  320 , a Testing Assessment Fact Sheet  322 , an Introduction to Testing Assessment Presentation  324 , a Testing assessment Engagement Schedule  326 , Testing Assessment Procedures  328 , a List of Interviewees and Documents Required  330 , a Testing Assessment Questionnaire  332 , Best Testing Practices  334 , and E-mail messages to be sent to client (which is not shown in  FIG. 3 ). The e-mail message to be sent to the client contains basic information about the testing assessment. The initial message may contain the Testing Assessment Fact Sheet  322  and the introductory Presentation  324 . The toolkit outputs consist of a Testing Assessment Dashboard Spreadsheet  336 , a Testing Assessment Report  338 , a Testing Practices Assessment Improvement Plan  340 , and a Testing Assessment Executive Presentation  342 . The toolkit outputs may also include a Gap Analysis Observations Review Meeting Minutes template, a Recommended Approach Review Meeting Minutes template, a Proposed Testing Practices Improvement Plan Review Meeting Minutes template, and a Presentation of Assessment Improvement Plan to Client Meeting Minutes template.  
         [0045]     The testing assessment statement of work document  320  is a document that serves as a contractual summary of all work necessary to implement a testing assessment and to provide the required products and services. The testing assessment fact sheet  322  is a document identifying what a testing assessment is, who performs one, and what outputs are produced. The Introduction to Testing Assessment Presentation  324  is a presentation, in a format such as, for example, Microsoft PowerPoint®, that contains an introduction to the Testing Assessment, indicating why an assessment could or should be performed and what benefits can result from the assessment. The Testing Assessment Engagement Schedule  326  is a schedule consisting of project task names, task dependencies, and task duration that together determine the start date and the end date of the project. The Testing Assessment Procedures  328  is a document identifying the inputs, procedure, and outputs used in a testing assessment. The List of Interviewees and Documents Required  330  is a document containing a list of team members that should receive the Testing Assessment Questionnaire and/or be interviewed by the consultant. This document also identifies the project documents that should be reviewed. The Testing Assessment Questionnaire  332  is a document containing detailed questions regarding Testing Organization, Testing Strategy, Test Planning, Testing Management, and Testing Environment and Tools. The Best Testing Practices Documents  334  are documents containing detailed best testing practices by stage as defined by the consultant&#39;s enterprise testing community and other industry measures.  
         [0046]     The Testing Assessment Dashboard Spreadsheet  336  is a spreadsheet where all the answers from the questionnaire are recorded. This spreadsheet contains formulas that analyze the answers and generate a “dashboard” view of the current state of the testing practices. The formulas utilized are dependent upon the particular industry or project being analyzed since the best practices for a particular industry may vary from that of other industries. The Testing Assessment Report  338  is a document used to record the observations, concerns, and recommendations that, if implemented, would, in the opinion of the consultant, improve the testing practices of the client organization. The questions are grouped into five main areas: Testing Organization, Testing Strategy, Test Planning, Testing Management, and Testing Environment and Tools. Each main area has a list of questions that should be answered and the results of those answers used to construct a graphical report such as that depicted in  FIG. 4 . The graphical report is part of the Testing Assessment Report  338  and can be presented to the client to provide a simple method of communicating the results of the Testing Practices Assessment. An example of a Testing Assessment Dashboard Spreadsheet  336  containing a Testing Assessment Questionnaire questions is depicted in Appendix A, the contents of which are hereby incorporated herein for all purposes.  
         [0047]     The Testing Assessment Improvement Plan  340  is a document used to record a recommended improvement plan based on the recommendations in the Testing Assessment Report document  338 . The Testing Assessment Executive Presentation  342  is a high-level executive summary presentation template, implemented, for example, as a Microsoft PowerPoint® template, that borrows designate key points from the Testing Assessment Report document  338  that focus on business benefits (e.g., improvements in efficiency that reduce time and/or cost and improvements in effectiveness that produce a quality product).  
         [0048]     The Gap Analysis Observations Review Meeting Minutes are meeting minutes captured in  306  “Conduct Gap Analysis with Lead Technologist or designated Subject Matter Expert”. Recommended Approach Review Meeting Minutes are meeting minutes captured in  309  “Review and Approve Recommendation/Strategy of Recommended Approach (with SME)”. Proposed Testing Practices Improvement Plan Review Meeting Minutes are meeting minutes captured in  311  “Implement Recommendations/Strategy (with Enterprise Managers)”. Presentation of Assessment Improvement Plan to Client Meeting Minutes are meeting minutes captured in  312  “Implement Recommendations/Strategy (with client)”.  
         [0049]     With reference now to  FIG. 4 , an example of a Graphical Testing Assessment Report is depicted in accordance with one embodiment of the present invention. Graphical report  400  is an example of a report that can be generated by a Testing Assessment Dashboard Spreadsheet  336  based on answers supplied by a consultant to questions in the Testing Assessment Questionnaire using formulas specific to the industry regarding best testing practices and can be presented to a client. Graphical report  400  contains a list of the five main areas of assessment: Testing Organization  402 , Testing Strategy  404 , Test Planning  406 , Testing Management  408 , and Testing Environment and Tools  410 . Each main area of assessment  402 - 410  contains sublevels as indicated. Each sublevel has an associated level  418  score, such as, A, B, or C indicating how successful the analyzed organization&#39;s testing practices are in that area.  
         [0050]     A bar chart is also provided for each sublevel as depicted in  FIG. 4 . The dotted bar graphs such as bars  430 - 438  indicate the maximal potential score that can be achieved for the particular sublevel. The actual score for a sublevel is indicated by the cross-hatched bars such as, for example, bars  420 - 428 . Areas having such sub-par assessment scores as to make them likely sources of severe problems have a darkened bar such as bars  412 - 416  corresponding, in this example, to sublevels Evaluation and Low-level Testing for main area Testing Strategy  404  and Test Specification Techniques in main are Test Planning  406 . This indicates that these areas need specific attention.  
         [0051]     In some preferred embodiments, bar graphs are illustrated in color to help aid the viewer in ascertaining the information presented. For example, in one embodiment, bars  412 - 416  might be illustrated in red to indicate that these are problem areas. Bars  420 - 428  may be illustrated in dark blue to indicate that actual rating for the particular area and bars  430 - 438  might be illustrated in light blue to illustrate the maximum possible rating for a particular area.  
         [0052]     Graphical report  400  is provided merely as an example of a graphical report that can be produced by the Toolkit of the present invention and is not intended to imply any limitations as regards the format of the graphical report.  
         [0053]     The toolkit supports consistent application of the testing assessment process and provides a visual “dashboard” (e.g., graphical report  400 ) view of the client&#39;s testing maturity. The toolkit includes a number of supporting documents and spreadsheets that lead to objective, measurable assessment findings and recommendations. Furthermore, the creation of the toolkit supports the ability to assess the state of testing using the industry concept of a maturity continuum, so that a consultant can clearly communicate to clients on the client&#39;s level of maturity and how to get to the next levels of maturity.  
         [0054]     In other embodiments, the areas of focus (testing organization, testing strategy, test planning, testing management, and testing environment and tools) could be changed. The assessment would therefore provide information on improving testing, but with different focal areas. If the number of focus areas is drastically increased, it would affect the amount of time required to complete interviews across all focus areas, and essentially broaden the scope of the engagement. This in turn would affect the speed at which the assessment could be completed and would increase the cost to the end client. The assessment could also use the same questions but alter their order. The organization and/or appearance of the dashboard (e.g., graphical report  400 ) view could also be altered.  
         [0055]     It is important to note that while the present invention has been described in the context of a fully functioning data processing system, those of ordinary skill in the art will appreciate that the processes of the present invention are capable of being distributed in the form of a computer readable medium of instructions and a variety of forms and that the present invention applies equally regardless of the particular type of signal bearing media actually used to carry out the distribution. Examples of computer readable media include recordable-type media such a floppy disc, a hard disk drive, a RAM, and CD-ROMs and transmission-type media such as digital and analog communications links.  
         [0056]     The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention, the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

                 Defect management is used integrally in each project. 
               
               
                 The defects originate from the various disciplines, those 
               
               
                 who develop the solution add their solution to the 
               
               
                 administration themselves, etc . . . Note: For low-level 
               
               
                 tests, the developers may want to record defects that 
               
               
                 will affect other units and other developers. 
               
               
                 Authorizations ensure that each user of the defect

                 A well-considered decision has been taken regarding 
               
               
                 the parts of the test execution that should or should not 
               
               
                 be automated. This decision involves those types of 
               
               
                 test tools and test activities that belong to the test

                 If the decision on automation of the test execution is a 
               
               
                 positive one, there is a tool for test execution.

                 tools should be reusable, means that the test tools that 
               
               
                 are used explicitly within one testing process need not

                 methodology of the testing process, which means that 
               
               
                 use of a test tool will not result in inefficiency or 
               
               
                 undesired limitations of the testing process.
