There are a few boogers in ‘using’ performance reviews as evidence of competence:
- What are the ‘objective’ criteria? Are they quantity related? (# produced, # defects ‘found’, #time s they violated procedures? - how do you measure that? Are they such that an individual person can be responsible for that metric? Or are they just blaming the operator from other’s mistakes or physics? Since most things that can be measured and that matter are based on a system of factors how do break it down to a single individual?
- Are they based on what their supervisor/manager and colleagues think of them? How do you know if this biased or not? (Ie how many ‘likes’ they got…
- From a privacy perspective, how can you even ‘show’ these to an auditor? Especially an internal auditor who has NO business seeing individual reviews?
I’ve seen reviews used to promote those the manager likes and ‘punish’ those the manager doesn’t like.
These can be remedied but I’ve experienced that those who can’t or won’t write an effective honest performance review are the same people who will whine and moan and NOT do anything approaching a true competence assessment because they like the current system which promotes their own incompetence (or laziness).
