Good quality is difficult to achieve, but can be attained. This new book spells out a process that teaches practitioners how to achieve an acceptable level of quality. Ultimately, quality application development is all about satisfying the needs of the user. This book spells out a way to achieve that and produce a software product that can evolve, scale, and change according to the needs of the user and the business. As the Unified Modeling Language is the industry standard, the book appeals to a broad audience by defining how to use the UML to enhance quality. The author helps the reader understand the elusive nature of this pursuit, and the important role that modeling plays in software quality. The book also points out advantages, disadvantages, strengths, weaknesses, traps, and pitfalls of using the UML.
