Richard N. Turner

Barry Boehm developed a conceptual version of the spiral model at TRW in 1978, but only in 1981 was he able to employ it in successfully, leading the development of a corporate TRW software development environment. SInce the formal publication of this model in 1988, he and his colleagues have devoted extensive efforts to clarifying and evolving it through several intermediate versions into the ICSM. He is the USC Distinguished Professor of Computer Sciences, Industrial and Systems Engineering, and Astronautics; the TRW Professor of Software Engineering; the Chief Scientist of the DoD-Stevens-USC Systems Engineering Research Center, and the founding Director of the USC Center for Systems and Software Engineering. He was director of DARPA-ISTO for 1989-92, at TRW for 1973-89, at Rand Corporation for 1959—73, and at General Dynamics for 1955-59. He is a Fellow of the primary professional societies in computing (ACM), aerospace (AIAA), electronics (IEEE), systems engineering (INCOSE), and lean and agile development (LSS), and a member of the U.S. National Academy of Engineering.

Jo Ann Lane is currently the systems engineering Co-Director of the University of Southern California Center for Systems and Software Engineering, a member of the Systems Engineering Research Center (SERC) Research Council representing the system of systems research area, and emeritus professor of computer science at San Diego State University.
