Biography

Dr. Raymond Madachy is a Research Assistant Professor in the Industrial and Systems Engineering Department and Principal of the USC Center for Systems and Software Engineering.  Prior to full-time research at USC he was Chief Science Officer at Cost Xpert Group.  Previously he was Chief Scientist at C-bridge Institute, where he led consulting and training in software methodologies and economic analysis.  Before that he was manager of the Software Engineering Process Group at at Litton Guidance and Control Systems achieving SEI CMM Level 4 after being the lead for software metrics, cost estimation and risk management at Litton Data Systems.  He has also served as a Visiting Scientist with the Software Engineering Institute

He is a co-author of the book Software Cost Estimation with COCOMO® II and is currently finishing the book Software Process Dynamics. His consulting clients have included Chevron, Northrop-Grumman, Seagate, Motorola, Lucent, USAA, Blue Cross and other Fortune 500 firms.  He has also performed as an expert witness on software cost, quality and contractual disputes.

He completed his Ph.D. in Industrial and Systems Engineering at USC in 1994. For his dissertation research, he developed a software project dynamics model for process cost, schedule and risk assessment. He also has an M.S. in Systems Science from the University of California, San Diego and a B.S. in Mechanical Engineering from the University of Dayton. He is a senior member of IEEE, ACM, INCOSE, Tau Beta Pi, Pi Tau Sigma, serves on the program committees for the International Forum on COCOMO® and Software Cost Modeling, the SPW/ProSim workshop, and has served on program committees for several other conferences. He previously served on the LA Software Process Improvement Network (SPIN) steering committee.

He lives with his wife Nancy and twin daughters in San Diego, CA. Ray enjoys bicycling and hiking up mountains in his spare time.
