Software quality managers require software to be tested before it is released to the market, and they do this … It directly affects the process quality and indirectly affects the product quality. Certain software quality attributes such as maintainability, usability, reliability cannot be exactly specified and measured. To carry out a technical analysis of product components or documentation to find mismatches between the specification and Alan Gillies lists four principal aspects of quality management for software development: However, software quality significantly differs from the concept of quality generally used in manufacturing mainly ISO 9001 is the most – Staff development plan. can develop own quality processes and they can still be ISO 9000 compliant companies. ISO 9001 1 requires top management to "... ensure that the planning of the quality management system is carried out ..." (refer clause: 5.4.2 Quality management system planning).
