  1. Quality Mgmt in S/W ? ByDr.S.Sridhar, Ph.D.(JNUD),RACI(Paris, NICE), RMR(USA), RZFM(Germany)DIRECTOR-TechnicalEinstein College of Engineering Quality Check in • programs • documents • data...

  2. Software Applications which need Quality • system software • real-time software • business software • engineering/scientific software • embedded software • PC software • AI software • WebApps (Web applications)

  3. Quality on Layered Technology Software Engineering Software Engineering tools methods process model a “quality” focus

  4. Quality in Process as Problem Solving

  5. The Primary Goal:High Quality Remember: High quality = project timeliness Why? Less rework!

  6. Quality from Analysis to Design

  7. Where Do We Begin? modeling Prototype Spec Design

  8. Quality thinking !

  9. Quality on Interface Design Easy to learn? Easy to use? Easy to understand?

  10. Golden Rules for quality • Place the user in control • Reduce the user’s memory load • Make the interface consistent

  11. Quality on Design Evaluation Cycle

  12. Quality Software Testing Testing is the process of exercising a program with the specific intent of finding errors prior to delivery to the end user.

  13. What Testing Shows errors requirements conformance performance an indication of quality

  14. Who Tests the Software? developer independent tester Understands the system

  15. Black-Box Testing quality requirements output input events

  16. Quality Testing Strategy unit test integration test system test validation test

  17. The Debugging Process test cases results new test cases regression tests suspected causes Debugging corrections identified causes

  18. Consequences of Bugs infectious damage catastrophic extreme serious disturbing annoying mild Bug Type Bug Categories: function-related bugs, system-related bugs, data bugs, coding bugs, design bugs, documentation bugs, standards violations, etc.

  19. WebApp Quality Factors
