Douglas W. Hubbard is the inventor of Applied Information Economics (AIE). He is an internationally recognized expert in the field of measuring intangibles, risks, and value, especially in IT value, and is a popular speaker at numerous conferences. He has written articles for InformationWeek, CIO Enterprise, and DBMS magazine. His AIE method has been applied to dozens of large Fortune 500 IT investments, military logistics, venture capital, aerospace, and environmental issues. Doug is the author of How to Measure Anything: Finding the Value of Intangibles in Business (Wiley).
The 2008 credit crisis, terrorism, Katrina, computer hackers, and air travel disasters all have something in common-the methods used to assess and manage these risks are fundamentally flawed. If risks cannot be properly evaluated, risk management itself becomes the biggest risk. The Failure of Risk Management shows you how to identify and fix these hidden problems in risk management.
Ineffective risk management methods, often touted as "best practices," are passed from company to company like a bad virus with a long incubation period: there are no early indicators of ill effects until it's too late and catastrophe strikes. Exploring why risk management fails—the failure to measure and validate methods as a whole or in part; the use of components known not to work; and not using components that are known to work—The Failure of Risk Management shows you how to measure the performance of risk management in a meaningful way, identify where risk management is broken, and fix it.
Respected expert and bestselling author Douglas Hubbard-creator of the critically praised Applied Information Economics (AIE)—uses real-world examples to reveal the serious problems in our current approaches to risk analysis. Hubbard skillfully illustrates how to use a calibrated risk analyses approach, and the many benefits that go along with it, along with checklists and practice examples to get you started.
One of the first resources to apply risk management across all industries, The Failure of Risk Management provides you with the tools you need to hit the ground running with radically better risk management solutions.
