John Doerr's Measure What Matters is about the importance of setting clear goals and using metrics to back them up. Doerr argues that metrics-driven OKRs (objectives and key results) have a considerable impact.
In contrast, Jerry Muller's The Tyranny of Metrics shows that measuring everything destroys our schools, hospitals, police and politics. When metrics is the most important, everyone will try to "game" the numbers. E.g., schools teach to the test rather than to educate.
