I've lived through unfair, biased and unhelpful perf reviews, I know what it's like to have this sky beam open up out of nowhere and vaporize you over absurd nonsense, but in a company of > 100 people you need a paper record of performance.
If you're a VP and suddenly someone asks, "Hey, can you promote or fire Person X?" What are you to go off of? Just a manager's recommendation? And you think perf reviews are biased?
Unfair performance reviews are usually a byproduct of bad managers. For ex: I knew fellow managers who never told reports what they were doing wrong, they'd wait til the end-of-the-year review and write vicious stuff. Why? It was hard to say face-to-face.
That's cowardly and not good mgt: you meet weekly or biweekly to discuss all issues, a well-run perf review is a boring rubber stamp on the 25 things you've been discussing all year.
This author suggests that employees present managers "handwritten notes" of their performance "in a notebook every 6-12 months." Guess what-- that's a performance review! As if the problem w/perf reviews was the formality of the process and not the human judgment being applied.
Again, I get it: performance reviews suck. But I think it's not the paperwork or the process, it's that management can be very inept at evaluating talent periodically, regardless of how that process is run.
Unfortunately, it's hard to run a company of > 100 people without written records of performance (especially if someone sues).
