Against metrics: how measuring performance by numbers backfires

Jerry Muller:

More and more companies, government agencies, educational institutions and philanthropic organisations are today in the grip of a new phenomenon. I’ve termed it ‘metric fixation’. The key components of metric fixation are the belief that it is possible – and desirable – to replace professional judgment (acquired through personal experience and talent) with numerical indicators of comparative performance based upon standardised data (metrics); and that the best way to motivate people within these organisations is by attaching rewards and penalties to their measured performance.
