"Doug has helped sharpen my ideas about testing. He's a well known and respected member of the context-driven testing community. He's one of the few people I am eager to teach with."

"When I met Doug, he was helping run Silicon Valley's ASQ. Public service has always been important to him. We explored our differences by teaching together, debating in front of the students. Our students (and I) learned a lot from him. Later, we jointly consulted to HP on test automation. He helped them through significant changes. I was proud to be associated with him."
