Booch served as Chief Scientist of Rational Software Corporation since its founding in 1981 and through its acquisition by IBM in 2003, where he kept working until March 2008. Afterwards, he became Chief Scientist, Software Engineering in IBM Research, and series editor for Benjamin Cummings. Booch has devoted his life's work to improving the art and the science of software development. In the 1980s, he wrote one of the more popular books on programming in Ada. He is best known for developing the Unified Modeling Language with Ivar Jacobson and James Rumbaugh in the 1990s.
Booch got his first exposure to programming on an IBM 1130.
... 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 . 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 developed the Booch method of software development, which he presents in his 1991/94 book, Object Oriented Analysis and Design With Applications. He advises adding more classes to simplify complex code. The Booch method is a technique used in software engineering. It is an object modeling language and methodology that was widely used in object-oriented analysis and design. It was developed by Booch while at Rational Software. The notation aspect of the Booch method has now been superseded by the Unified Modeling Language, which features graphical elements from the Booch method along with elements from the object-modeling technique and object-oriented software engineering. Methodological aspects of the Booch method have been incorporated into several methodologies and processes, the primary such methodology being the Rational Unified Process.
Design patterns
Booch is also an advocate of design patterns. For instance, he wrote the foreword to Design Patterns, an early and highly influential book in the field.
He now is part of IBM Research - Almaden, serving as Chief Scientist for Software Engineering, where he continues his work on the and also leads several projects in software engineering that are beyond the constraints of immediate product horizons. Grady continues to engage with customers working on real problems and maintains deep relationships with academia and other research organizations around the world. Grady has served as architect and architectural mentor for numerous complex software-intensive systems around the world in just about every domain imaginable.
