Watts S. Humphrey (1927–2010) was a pioneering American software engineer. He is known as the “father of software quality” for developing the Capability Maturity Model for measuring the maturity of an organization’s process for developing and refining software.
Born in Battle Creek, Michigan, Humphrey served in the Navy and got Bachelor of Science in physics from the University of Chicago, a master of science in physics from Illinois Institute of Technology, and an MBA from the University of Chicago despite his learning disorder. After working at Sylvania Labs and IBM, Humphrey joined the Software Engineering Institute (SEI) at Carnegie Mellon University. It was there that Humphrey established the Software Process Program which developed the Capability Maturity Model Integration (CMMI), a framework of best practices for software engineering. CMMI has been adopted by thousands of organizations around the world.
