  9. 9. Test / QA – Process Roadmap
  10. 10. Test / QA – Process Roadmap Establish Requirements Project Test Case and Project Test Planning Standards / QA Development Scope Method Lessons Quality User System Learned / Assurance Acceptance Validation Continuous Testing Testing Improvement 10
  11. 11. Requirements & Project Scope  Requirements are collected and analysed  Requirement documented - reviewed, finalised and agreed upon by all project participants  Testing scope of the project is established and agreed upon 11
  12. 12. Establish Project Standards  QA team will assist in establishing and setting the standards for the project  The standards established for:  Development Methodology  System Design  Quality Assurance Methodology  Methodology Compliance 12
  13. 13. Quality Methodology  The QA team will establish Quality Assurance methods, practices and standards  The overall QA methodology will assist in creating a controlled product release and greatly reduce the risk of errors being introduced into the product 13
  14. 14. Test Planning  QA Team will:  Write the Test Plans which detail the QA involvement for the entire project life cycle  Develop test conditions based on the business needs and business scenarios  Implement a defect-tracking mechanism 14
  15. 15. Test Case Development  Test cases written to test the scenarios covered in the test conditions  Review the test conditions and subsequent test cases with the project users  Write test cases that will cover all phases of the QA life cycle 15
  16. 16. Quality Assurance (QA) Testing  QA normally consists of 5 types of testing:  Unit Testing  Functional Testing  System Integration Testing  Regression Testing  User Acceptance Testing 16
  17. 17. User Acceptance Testing  The testing of the entire application by the end-users ensuring the application functions as set forth in the system requirements documents and that the system meets the business needs 17
  18. 18. System Validation  All systems should go through a validation process 18
  19. 19. Types of Testing
  20. 20. Testing Types UNIT FUNCTIONAL INTEGRATION PERFORMANCE Individual Full Modular Cross Modular Stress and Components Testing Testing with all Volume Testing or Module Development & Technical Components 20
  21. 21. Testing Types  Unit Testing  Functional Testing  Performance / System Integration Testing  Regression Testing  User Acceptance Testing 21
  22. 22. Unit Testing  The testing of the application modules to verify each unit (module) itself meets the accepted user requirements, design and development standards 22
  23. 23. Functional Testing  The testing of all the application’s modules individually to ensure the modules, as released from development to QA, work together as designed and meet the accepted user requirements and system standards 23
  24. 24. System Integration Testing  Testing of all of the application modules in the same environment, database instance, network and inter-related applications, as it would function in production.  This includes security, volume and stress testing 24
  25. 25. Regression Testing  Testing each of the application’s system builds to confirm that all aspects of a system remain functionally correct after program modifications.  Automated regression testing tools is the preferred method 25
  26. 26. User Acceptance Testing  The testing of the entire application by the end-users ensuring the application functions as set forth in the system requirements documents and that the system meets the business needs 26
  27. 27. Personnel Involved
  28. 28. Personnel  QA Manager  Business Analyst  Quality Assurance Analyst  Technical Writer  Instructional Designer/System Trainer 28
  29. 29. QA Manager  Establishes and implements the QA Methodology for the project’s quality  Acts as the project lead liaison between all project areas to ensure all areas are completely and correctly engaged  Oversees the entire QA Life Cycle and QA staff 29
  30. 30. Business Analyst  Writes the User Requirements and Functional Specs and assists in writing the system documentation  Acts as a liaison between the QA Team and the other project team members  Assists in the QA test conditions development 30
  31. 31. Quality Assurance Analyst  Develops test conditions  Writes test cases  Performs Functional, Regression, and System Integration Testing  Assists in development of user guides and training manuals  Assists or performs the System Training 31
  32. 32. Technical Writer  Assists in writing the user and system documentation  Maintains validation documentation  Writes on-line help  Writes the User Guide and Training Manuals 32
  33. 33. Instructional Designer / Systems Trainer  Assists in writing the user guides and training manuals  Trains users on production system  Subject Matter Expert on Adult Learning Theories and learning assessment 33
  34. 34. QA on Test Deliverables
  35. 35. Testing Documentation  Test Strategy  Test Plan Development  Test Case Development  Test Scenarios Development  Test Metrics / KPI  Internal Audit Reviews  User Reviews  Historical Information 35
  36. 36. Test Metrics
  37. 37. Testing Metrics Metric Test Development Metrics Test Execution Metrics Type Functional  Number of requirements  Number of requirements verified Metric allocated by test  % of requirements tested by each  % of requirements by test business process (procure to payment, development phase order to cash etc)  Stability of server/platform per user Problem  Problems tested for in  Problems found per business process Metrics regression tests function  Extreme conditions tested  Problems found per software component for in functional tests  Number of critical/high problems found per business process Schedule  % completion of functional  Tests completed per functionality Metrics test requirements by  Estimated number of days to complete testing phase  Test cycle completion time  Weighted functional  Time to complete testing per functional requirement completion area 37
  38. 38. Conclusion  QA’s involvement must be from the beginning to the end of the project life cycle.  Properly managed, the QA process will bring the system to production with cost and time savings. 38
