If a job is complex, multifaceted and involves subtle trade-offs, the best approach is to hire good people, pay them the going rate and tell them to do the job to the best of their ability. Absolutely, could not agree more. This is the only way to beat gamification of metrics in my opinion. There is a worrying trend of treating staff as equally capable but untrusted cogs in a wheel, and metricising performance. I fun…
That's a great way of summing up what I've heard called "managerialism".
There's a theory behind, e.g., the MBA that a competent manager can manage anything. That what one manages makes no difference as long as you're a real manager. One of the corollaries of that theory is that all one has to do is find the right short-term metrics and make them go up and to the right.
I don't think this theory makes much sense when you examine it. But it's excellent at justifying a caste system, one where all workers are controlled by wise managers, and where there's a stable hierarchy of executives above that. I note that the hierarchy established is basically equivalent to those of feudalism. It also has the handy property of justifying high compensation for managers and executives; since workers are cogs and higher-ups do the important thinking, all gains should flow upward.
There are other ways of organizing things, of course. But this has become such the default that people have a hard time even imagining alternatives.
