Our approach stands on the intellectual shoulders of several disciplines, individuals and activities:
Decision Analysis; Ron Howard of Stanford University defined the profession of decision analysis in 1964, and has guided the field as professor in the Department of Engineering-Economic Systems in the School of Engineering at Stanford.
READINGS on the Principles and Applications of Decision Analysis (Volumes I and II), Eds. Ronald A. Howard and James E. Matheson, Strategic Decisions Group, Menlo Park, California, 1984.
The Psychology of Judgement and Decision-making; leaders in this field included Daniel Kahneman and Amos Tversky.
Their publication in 1974: Judgement Under Uncertainty: Hueristics and Biases, was a ground breaking work, and has been updated recently by Daniel Kahneman's new book "Thinking, Fast & Slow". It will change your perspective on how you and your organization perceive and process information.
The experience of applying decision analysis at General Motors in the late 1980s thru the 1990s; this work clarified the differences and relevance of multi-decision maker environments, and how overcoming those challenges can create insight and high-value outcomes in complex environments.
This was partially documented in "The Unifying Vision Process: Value beyond Traditional Decision Analysis in Multiple-Decision-Maker Environments," Interfaces 22:6  150-166, by Kusnic, M.W. & Owen, D.
