I worked at a company where every year we'd decide we were going to do OKRs or something similar, and we "were going to do it right this time".

We'd spend weeks in meetings coming up goals and things we could measure, and end up with something like, "increase foo from X% to Y%". Here, "foo" is a placeholder for something or other, but the X and Y are not. We would literally leave them as variables, under the impression we'd fill them in eventually.

A year later, we'd look at them again and see that we never filled in the numbers. Then repeat. It was pretty wild.
