An integrated life cycle quality model for general public market software products

The business value of the software product results from its ultimate quality seen by both acquirers and end users. An integrated life cycle quality model, further called complement model for software product quality combines high level quality view of TL9000 Handbook and detailed view from ISO/IEC 1926 in the process of defining, measuring, evaluating and finally achieving appropriate quality of usercentered software product. This paper presents how the use of TL9000 product operational (in-the-field) quality measures can bring benefits to setting up, measuring and evaluating the quality of the software product being developed, through its entire life cycle. The process of building quality into a software product is discussed and illustrated by TL9000-ISO complement model as well as by application process walk-through.
