Brian Marick graduated in 1981 with one degree in Mathematics and Computer Science and another one in English Literature. In his early career, he continued to be confused about his identity. Sometimes he was a programmer. Sometimes he was a tester. He became better at each because he understood the other.

Brian is the author of The Craft of Software Testing, which promotes test design techniques, how testers support the team, and unscripted exploratory manual testing. He was an author of the Manifesto for Agile Software Development and was the second chair of the Agile Alliance board of directors. Because the Agile methods encourage cross-disciplinary work, he's once again without a fixed identity. When consulting, he sticks his nose into everything.
