Kay Pentecost is fascinated by programming, people, process, and chocolate. Ms. Pentecost has been a technical writer, Unix systems administrator, expert system developer, team lead, trainer, and programmer. She currently does Windows applications development in Visual Basic as a contractor and consultant. Ms. Pentecost is curious about excellence and mastery in software development and how to help a development team excel. She thinks the answers lie in the Extreme Programming practices, and she is working on becoming an expert in them. She has been practicing test-driven development for some time now and has authored the Visual Basic chapter in a forthcoming book about test-driven development. Ms. Pentecost has a B.B.A. in accounting and an M.S. in information systems technology. She bakes an excellent cheesecake, which she hopes to share with an XP team soon.
