Smart Choices: A Practical Guide to Making Better Decisions
John S. Hammond, Ralph L. Keeney, Howard Raiffa
The book that introduced the PrOACT framework. Practical, accessible, and still the best one-volume introduction to structured personal and professional decision-making. Perspicuity's PrOACT flow follows this book directly.
Decision Quality: Value Creation from Better Business Decisions
Carl Spetzler, Hannah Winter, Jennifer Meyer
The Strategic Decisions Group's textbook on the "six links" of decision quality. The book Perspicuity's Decision Quality Check-in is built on. Less personal, more organizational than Smart Choices.
The foundational popular text on the two systems of thought and the cognitive biases that warp our decisions. Read this once and you'll see your own reasoning differently for the rest of your life.

Noise: A Flaw in Human Judgment
Daniel Kahneman, Olivier Sibony, Cass R. Sunstein
Companion to *Thinking, Fast and Slow* about a different problem: the hidden variability in expert judgment. Two doctors, two judges, two underwriters looking at the same case routinely reach different conclusions — and that variability is invisible to the people inside the system.
