I do like the idea. Maybe there’s a distinction between direct productivity and indirect, overhead-like contribution? Sort of the difference between gross margin and net income?

But it’s tough. As a product manager, I think that the right spec can greatly increase engineering efficiency. If that’s true, and bear with me, spending an extra 20 hours on a spec might save 1000 hours of dev time. Isn’t that the same as making those devs more productive? So do we count that work as 20 hours, or 1000 hours?

I like it in principle but I’m not sure it scales across disciplines.
