Without that, how can you charge back your time to the customers, versus your employer? How much is coming out of the internal training budget? Pull numbers out randomly, how does your company function?
As I said; measurable deliverables. And those would be deliverables that are averaged over a reasonable period of time. Completion of project milestones or at least good write-ups and reasons as to why those milestones and deadlines are missed. That's less draconian than what you're proposing and works great in companies I've worked at.
If it's any consolation, some of my peers subscribe to the model you proposed... some of their people have ended up on my team and I get consistently good reviews from my people about my management style.
I tend to subscribe to the idea that I should trust my people to do their jobs to the best of their abilities, and to assist them if it's beyond their capabilities or they have good reasons not to perform. I do have the luxury of working for a large enough company with deep enough coffers that we can usually carry some dead wood in a team for quite a while with minimal hit to the bottom line... and that gives me the latitude to average their performance over a 6 month or even a 1 year period. But privately I know pretty quickly who the dead wood is and I will usually find ways to move them off to someone else's team or get them out before they affect the rest of the team.
Being a manager is hard work. What you proposed is management by Excel sheet which is unfortunately rife in Corporate America thanks to MBA's who think they know what'll make a business better but actually only have an academic understanding of what works, not real-world experience.
And I'll admit; when I was a new and freshly minted manager I did do that because that's what my manager taught me. I learned pretty quickly how badly that works from experience and tried a different tack. Yes, my management often asks me for details like you're asking for... but by knowing my team, my deliverables and my targets allows me to speak intelligently to what my team is doing and justify the salaries of everyone on that team consistently year over year. I also have the highest average tenure of a team member of any of my peers.
