Where to Start with Douglas Hubbard
Douglas W. Hubbard is the inventor of Applied Information Economics and one of the world’s foremost experts on measuring things that organizations insist cannot be measured. His consulting work has helped enterprises quantify everything from cybersecurity risk to the value of employee training. His books challenge a deeply held assumption in business: that some things are simply too soft, too complex, or too abstract to put a number on. Hubbard demonstrates, with mathematical precision and practical case studies, that this assumption is nearly always wrong.

How to Measure Anything
Douglas W. Hubbard · 432 pages · 2014 · Challenging
Themes: measurement, quantitative analysis, risk assessment, decision analysis, business metrics
The book that shatters the myth of the immeasurable. Hubbard proves that if something matters enough to influence a decision, it can be observed and therefore measured, often with far simpler methods than people assume.
Why Start Here
This is Hubbard’s foundational work and the one that contains his complete measurement philosophy and methodology. His later books on cybersecurity risk and project management apply the same principles to specific domains, but this is where you learn the underlying framework.
The book begins by challenging what “measurement” even means (it is the reduction of uncertainty, not the achievement of precision) and then walks you through calibrated estimation, the value of information analysis, and practical sampling methods. You will learn to assess your own confidence levels, figure out which measurements actually matter for a given decision, and start quantifying things your colleagues insist are impossible to measure.
The third edition includes expanded material on risk analysis and new case studies from organizations that have put these methods into practice.
What to Expect
A methodical, intellectually stimulating book that requires more effort than the other books in this guide. Some sections involve probability concepts and statistical reasoning, though Hubbard explains everything clearly. Downloadable spreadsheets accompany the exercises. Best approached after you have built comfort with statistical thinking through Kahneman and Wheelan.
