You might have heard that if you can’t measure you can’t manage. You might have believed it, too. And if you think you need metrics to manage you might be feeling guilty about not having enough of them.
Guilt no more. Good metrics are hard to craft, harder to manage, expensive to maintain, and perishable besides.
Bad metrics, in contrast, are easier all the way around, but that doesn’t matter. Bad metrics are worse than no metrics. If a bad metric isn’t lying to you outright, it’s directing your attention to what doesn’t deserve your attention.
