Management of software testing

During the building of software, there will be a number of test points. Clearly, the software developer will test the software as development progresses.Additionally the software developed by each programmer must be integrated into a complete system. This require testing of interfaces between modules and other components of the system. The software must be tested to see that it meets the requirements. In agile software development it is the test that drives the software development.A test is designed which the software will fail initially. Software and systems testing requires quality management systems, which include a number of practical steps including walkthroughs and inspections. Various standards and approaches are available which can be used as part of the discipline of software quality assurance.

Question: Introduce software quality assurance and explain the role of a software quality manager. Explain some of the standard approaches to software quality management including the use of ISO9000, TickITPlus, and the Capability Maturity Model Integration (CMMI). Explain how a walkthrough should be conducted.How does a walkthrough differ from a formal inspection such as Fagan's inspection? How can a software quality assurance system help?
