Introduction to structuring decisions
David R. Smith
2020, Book chapter, Structured decision making: Case studies in natural resource management
Decision structuring, also known as decision framing, provides the foundation and roadmap for analyzing a decision. For decisions that warrant a systematic approach, structuring begins with identifying the problem for analysis, which sounds simple but can be deceptively difficult because decision problems are often ill-formed at the start....
