Jerry Z Muller:

Organisations in thrall to metrics end up motivating those members of staff with greater initiative to move out of the mainstream, where the culture of accountable performance prevails. Teachers move out of public schools to private and charter schools. Engineers move out of large corporations to boutique firms. Enterprising government employees become consultants. There is a healthy element to this, of course. But surely the large-scale organisations of our society are the poorer for driving out staff most likely to innovate and initiate. The more that work becomes a matter of filling in the boxes by which performance is to be measured and rewarded, the more it will repel those who think outside the box.

Economists such as Dale Jorgenson of Harvard University, who specialise in measuring economic productivity, report that in recent years the only increase in total-factor productivity in the US economy has been in the information technology-producing industries. The question that ought to be asked next, then, is to what extent the culture of metrics – with its costs in employee time, morale and initiative, and its promotion of short-termism – has itself contributed to economic stagnation?
