Peter Coad is the innovator behind the leading software development method that bears his name. Coad is perhaps the world's most experienced object-model builder: hundreds of object models to date. He founded Object International in 1986; its mission is “helping teams deliver frequent, tangible, working results.”
Mark Mayfield is an utterly pragmatic object-oriented developer who is also the president of JEN Consulting. Working together with Peter Coad since 1991, Mayfield helps teams build effective object models and guides them all the way through to project completion.
