Learn why focusing on numbers often destroys value, from Soviet nail factories to modern corporate KPIs.
"The Broken Measure – When a metric becomes a target it ceases to be a good measure" is a deep dive into Goodhart's Law. It explains why data-driven management often leads to disaster. The book uses the famous example of the Soviet nail factory: When targets were based on the number of nails, the factory produced millions of tiny, useless nails. When targets were based on weight, they produced a few giant, useless heavy nails.
Author David Scale explains how this applies to modern life: standardized testing in schools ruins education, and measuring programmers by lines of code ruins software. Whenever a measure becomes a goal, people game the system to hit the number, destroying the actual value.
"The Broken Measure" teaches leaders how to design "un-gameable" metrics. It is a guide to looking beyond the dashboard and understanding that what really matters often cannot be counted, and what can be counted often doesn't matter.
