Diagramming and process are important topics in today's software development world, as the UML diagramming language has come to be almost universally accepted. Yet process is necessary; by themselves, diagrams are of little use. This is underscored by the number of recent books explaining Extreme Programming (XP), which many believe goes too far toward having no structure or no method. This book combines the notation of UML with the lightweight but effective ICONIX process. The work functions as an up-to-date edition of the authors' successful Use Case Driven Object Modeling with UML: A Practical Approach (Addison-Wesley). Sitting between the free-for-all of XP and overly rigid processes like RUP, ICONIX offers enough structure to be successful. ICONIX has attracted a growing following; for example, Sparx Systems' Enterprise Architect CASE tool (with 80,000+ copies in the field), which directly supports ICONIX as an option, presenting online help material on ICONIX.
