Career and research

Booch worked at Vandenberg Air Force Base after he graduated. He started as a project engineer and later managed ground-support missions for the space shuttle and other projects. After he gained his master's degree he became an instructor at the Air Force Academy. Booch served as Chief Scientist of Rational Software Corporation from its founding in 1981 through its acquisition by IBM in 2003, where he continued to work until March 2008. After this he became Chief Scientist, Software Engineering in IBM Research and series editor for

... I pounded the doors at the local IBM sales office until a salesman took pity on me. After we chatted for a while, he handed me a Fortran anual I'm sure he gave it to me thinking, "I'll never hear from this kid again." I returned the following week saying, "This is really cool. I've read the whole thing and have written a small program. Where can I find a computer?" The fellow, to my delight, found me programming time on an IBM 1130 on weekends and late-evening hours. That was my first programming experience, and I must thank that anonymous IBM salesman for launching my career. Thank you, IBM.

Booch method

Booch developed the 'Booch method' of software development, which he presents in his 1991/94 book, ''Object Oriented Analysis and Design With Applications''. The method was authored by Booch when he was working for

and benefited from ample documentation and support tools. The Booch notation is characterized by cloud shapes to represent classes and distinguishes the following diagrams: The process is organized around a macro and a micro process. The macro process identifies the following activities cycle: * Conceptualization : establish core requirements * Analysis : develop a model of the desired behavior * Design : create an architecture * Evolution: for the implementation * Maintenance : for evolution after the delivery The micro process is applied to new classes, structures or behaviors that emerge during the macro process. It is made of the following cycle: * Identification of classes and objects * Identification of their semantics * Identification of their relationships * Specification of their interfaces and implementation The notation aspect of the Booch method has now been superseded by the
