> I’ve seen cases where folks completely checked out and were contributing nearly nothing, making no commits, writing no code, and faking it at standups. Simple metrics can help surface cases like this.

Of course we've all seen varying degrees of this - but these kind of people can only exist because of terrible management. Throwing metrics at the problem just introduces a more insidious version of this individual, one that knows how to game whatever metrics are used (managers especially will do this). I've been on teams where such an individual could thrive for years, even with promotions, and on teams where such an individual would be outed within a week.

In one of those cases I was the bad manager. The data was a wakeup call that made me understand the magnitude of the problem.

In another case, I knew the manager well, having been on his team before. He was effective, empathetic, and inspirational. He was also overworked and perhaps a bit naively assumed good intent from everyone. The data let me explain to him that the coworker was not contributing and he had a real problem.

If you need metrics to see an employee isn't doing what you assigned to them, what are you even being paid to do?

You’re being paid to make your whole team as effective and capable as possible while satisfying your leadership and stakeholders. And to help your boss do that with his team by developing your peers. And…

Detecting slackers efficiently is simply never going to be a top priority. You have to trust your people. Usually it’s incredibly rewarding.

Inflating the engineering department head-count, a very important metric for c-level resumes.

This is called "broken clock shows the right time twice a day."

Also c'mon, fooling commit metrics is silly easy, just _also_ one of the most burn-out and check-out inducing things ever. And at senior level you _HAVE_ to do that these days. You _have_ to inflate them.

Your broken clock isn't free.
