Software quality measures

• (quality of design)- conformance to explicitly stated functional and performance requirements, explicitly documented development standards and implicit characteristics

• (quality of conformance)- how valid the design and requirements are

Generalized Software Quality Approach

two approaches

• the procedural approach -procedures and guidelines for the review and testing activities are established

• the quantitative approach- – setting a quantitative quality goal – then managing the software development process

quantitatively

• Benchmarked against world-class standards and models such as ISO 9001-TickIT, SEI-CMM / CMMI, ISO 20000, ISO 27000, AS 9100, TL 9000 and ISO 14001
