Peter Coad (born December 30, 1953) is a software entrepreneur and author of books on programming. He is notable for his role in defining what have come to be known as the UML colors, a color-coded notation chiefly useful for simplifying one's understanding of a design or model.
In 1986, Peter Coad founded Object International, a software consulting firm where he served as President.
During the 1990s Coad co-authored six books on the analysis, design, and programming of object-oriented software. During this time Coad became famous through his work on the Coad/Yourdon method for Object-oriented analysis (OOA) which he had developed together with Edward Yourdon. He is considered a supporter of the lightweight methodology called Feature Driven Development (FDD), which was developed primarily by co-author Jeff De Luca.
In 1999, Coad was one of the founders of the software company TogetherSoft, where he served as Chairman, CEO, and President.
Coad became senior vice president and chief strategist of Borland Software Corp. when Borland bought TogetherSoft in January 2003. Coad left Borland before the end of 2003 and turned his attention to interests outside of the software development field, especially simplified teaching techniques for learning to read The Bible in its original languages.
