Summary:
The book critiques the modern obsession with quantifying human performance through metrics, arguing that this approach can lead to counterproductive outcomes, gaming of the system, and a neglect of important but less measurable aspects of organizational and individual success. It delves into case studies across various sectors, including education, medicine, business, and government, to illustrate the pitfalls of overreliance on metrics and the importance of professional judgment.
Key points:
1. Metric fixation: Muller's book discusses the concept of "metric fixation," or the belief in replacing professional judgment with numerical performance indicators. This can lead to system manipulation, excessive costs, and resource diversion.
