While leading projects at Bell Laboratories (where his life as a tester began), The Whitewater Group, and Microsoft, Jim McCarthy saw that the best way to build products was by focusing on the team. He led the creation of the Visual C++ team. Much of Microsoft benefitted from Jim’s ideas as articulated in his book, Dynamics of Software Development. His approach and observations formed the basis of Microsoft Solutions Framework and were a catalyst for the extreme and agile programming movements. Jim and his wife Michele, coauthors of Software for Your Head, run McCarthy Technologies, Inc., providing technology, training, and consulting that enable organizations and teams to consistently generate the greatest possible results.
