Elizabeth K Clark


Elizabeth K Clark received her B.A. from Stanford University and her Ph.D. in Cognitive Psychology from U.C. Berkeley. Betsy has spent more than 45 years implementing software measurement programs, estimating costs and schedules, and assessing risks to schedule performance. She is the President of Software Metrics Inc., a Virginia-based consulting company she founded in 1983. Betsy was a primary contributor to Practical Software Measurement and to the SEI’s core measures. She is also a principal contributor to the Australian Defence’s Schedule Confidence Risk Assessment Methodology (SCRAM) which has been used to identify root causes of schedule slippage on more than 50 different Australian and US defense programs, including the F-35 Joint Strike Fighter. Betsy collaborated with Barry Boehm and Chris Abts to develop the COCOTS model. She developed the first examination for IPPUG’s certification for Measurement Professionals. Betsy was a long-time consultant to the Institute for Defense Analyses and, more recently, to the Software Engineering Institute. In 2023, Betsy co-authored a book about the F-35 Joint Strike Fighter with Tom Burbage (the F-35 General Manager at Lockheed Martin for 13 years) and Adrian Pitman from the Australian Department of Defence (F-35: The Inside Story of the Lightning II, Skyhorse Publishing, 2023). The book is based on more than 100 interviews with key individuals from the US Government, Lockheed Martin and other contractors and the international partner countries. Betsy met her husband, Brad Clark, at a COCOMO conference in 1997 years ago. They live in Haymarket, Virginia. Betsy also spends a lot of time Queensland, Australia where she is a Director at the non-profit Independent Project Review Institute. Betsy is a long-time equestrian and, more recently, has taken up triathlons where she is usually the oldest female participant. She has completed four 70.3 half Ironman races and is currently training for her first full Ironman race in Western Australia in December 2024.
