『Failure of Risk Management』の著者について

Douglas W. Hubbard, bestselling author of The Failure of Risk Management: Why It’s Broken and How to Fix It, is a pioneering management consultant and founder of Hubbard Decision Research. A leader in decision sciences and actuarial risk analysis, Hubbard developed the Applied Information Economics (AIE) framework, which integrates quantitative methods like Bayesian analysis and Monte Carlo simulations to overhaul outdated risk management practices. His work critiques reliance on non-quantitative tools like risk matrices, advocating instead for probabilistic, data-driven strategies validated across industries from cybersecurity to finance.

Hubbard’s expertise stems from three decades of consulting for Fortune 10 companies, government agencies, and military organizations. He is also the author of the influential How to Measure Anything: Finding the Value of Intangibles in Business, a global bestseller required in actuarial exams and university curricula.

His books, translated into eight languages, have sold over 130,000 copies worldwide. Recognized with the 2017 PaloAlto Networks Cybersecurity Canon Award and named a Royal Society of Arts Fellow, Hubbard’s methods shape risk management protocols for enterprises seeking measurable, evidence-based solutions.

『Failure of Risk Management』に関するよくある質問

What is The Failure of Risk Management by Douglas W. Hubbard about?

The Failure of Risk Management critiques traditional risk-assessment methods like risk matrices and expert intuition, arguing they lack scientific rigor. Hubbard advocates for quantitative approaches, such as calibrated probability estimates, Monte Carlo simulations, and Applied Information Economics, to measure and mitigate risks objectively. The book emphasizes testing models against real-world data and building dedicated risk-management teams to address systemic failures.

Who should read The Failure of Risk Management?

Risk managers, corporate decision-makers, and professionals in finance, project management, or cybersecurity will benefit most. The book is ideal for skeptics of qualitative risk frameworks and those seeking data-driven methods to quantify uncertainties. Hubbard’s insights also appeal to academics studying actuarial science or decision theory.

Is The Failure of Risk Management worth reading?

Yes, particularly for its rigorous critique of outdated methods and actionable solutions like probabilistic modeling. While some sections are technical, Hubbard balances theory with real-world examples (e.g., the 2008 financial crisis). Critics note occasional repetition, but the book remains a seminal guide for modernizing risk practices.

What are the main ideas in The Failure of Risk Management?

• Flawed methods: Risk matrices and expert intuition often amplify biases.
• Quantitative fixes: Use probability calibration, Monte Carlo simulations, and empirical validation.
• The Risk Paradox: Major risks receive less analysis than minor ones.
• Collaboration: Cross-industry data sharing improves risk models.

How does Douglas W. Hubbard define "calibration" in risk management?

Calibration involves training experts to make accurate probability estimates through feedback and tests like the "equivalent bet" method. Hubbard argues this reduces overconfidence and aligns subjective judgments with measurable outcomes, a process detailed in his "premortem" analysis technique.

What is the "Risk Paradox" in The Failure of Risk Management?

Hubbard’s Risk Paradox highlights how organizations often apply sophisticated analysis to low-stakes operational risks while using superficial methods (or none) for existential threats. This mismatch exacerbates systemic vulnerabilities, as seen in corporate collapses and engineering disasters.

How does The Failure of Risk Management critique traditional risk matrices?

Hubbard calls risk matrices “no better than astrology” due to their arbitrary scoring scales, inconsistent categorization, and inability to quantify probabilities. He demonstrates how they create false precision, overlook correlations between risks, and fail empirical validation.

What is Applied Information Economics (AIE) in the book?

AIE is Hubbard’s methodology to quantify uncertainties using Bayesian statistics, decision trees, and value-of-information analysis. It prioritizes measuring key variables to reduce decision-making uncertainty, exemplified in case studies from oil exploration to cybersecurity.

What are key quotes from The Failure of Risk Management?

• “The most sophisticated risk analysis methods are often applied to low-level operational risks.”
• “Expert intuition is overvalued… initial measurements reduce the greatest uncertainty.”
• “Risk management needs Chief Probabilities Officers, not Chief Risk Officers.”

How does The Failure of Risk Management address the 2008 financial crisis?

Hubbard cites the crisis as a failure of qualitative risk models (e.g., flawed credit ratings) and siloed data. He argues quantitative metrics, like probabilistic default rates and stress-testing simulations, could have exposed systemic leverage risks earlier.

How does this book compare to Hubbard’s How to Measure Anything?

Both books advocate data-driven decision-making, but The Failure of Risk Management specifically targets risk professionals. It expands on measurement techniques with sector-specific case studies and introduces AIE as a framework for enterprise risk.

Why is The Failure of Risk Management relevant in 2025?

With rising cyber threats, AI governance challenges, and climate-related financial risks, Hubbard’s call for probabilistic modeling and cross-industry collaboration remains urgent. Updated editions integrate Excel-based tutorials and post-COVID risk analysis.
