  3. What are the common software quality assurance practices among Rational Unified Process (RUP), Microsoft Solution Framework (MSF) and Extreme Programming (XP)?
  4. Discuss the aspects of Software Quality Support in XP.
  5. What are the 3 objectives of SQA activities in software development?

Part 4

  1. Discuss what an interface of a module is. Give an example from the project you developed as part of QA.
  2. What is 'Content Coupling'? Why is not desirable?
  3. Discuss the processes of Validation and Verification. Explain how these two processes became real at the time of presenting your program you developed as part of QA.
  4. Consider the following piece of code. Develop the Control-flow diagram for the piece of code and suggest the nodes, edges or paths where test cases may be designed.

  1. Why is 'Data-Coupling' is an acceptable practice. give an example from the project you developed as part of QA.
  2. For the program you developed as part of QA, it had eight stages in the following order. First you (1) collected the requirements, then you (2) developed the GUI, (3) made some design decisions, (4) designed how data could be handled, (5) did programming, (6) developed test cases, (7) peer-reviewed it before finally (8) presenting your programme. Can you develop a PERT chart using the time taken to do each task as well as the dependencies between the tasks?
  3. Consider the following snippet of code. Identify the kind of coupling present in this piece of code. Rewrite the code to remove the existing coupling and to make it modular.
