The Booch method is a method for object-oriented software development. It is composed of an object modeling language, an iterative object-oriented development process, and a set of recommended practices. The Booch method helps to design systems using the object paradigm. It covers the analysis- and design phases of an object-oriented system. The method defines different models to describe a system and it supports the iterative and incremental development of systems.
