Booch is best known for developing the Unified Modeling Language with Ivar Jacobson and James Rumbaugh. He also developed the Booch method of software development, which he presents in his book, Object Oriented Analysis and Design. He advises adding more classes to simplify complex code. 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.) In the 1980s, Booch wrote one of the more popular books on programming in Ada.
