The book is not about the evils of measurement of human performance, or of rewarding achievement, or of transparency. It is about “metric fixation”—a perversion of these, based upon beliefs that seem reasonable at first, but turn out to be unreasonable in practice. The title, The Tyranny of Metrics is not meant to convey the message that metrics are intrinsically tyrannical, but rather that they are frequently used in ways that are dysfunctional and oppressive.
