(the following refers specifically to performance reviews for software and QA engineers)
Here's a question: are performance reviews antithetical to a start-up environment?
I don't think so. As long as the group is big enough to have a manager or leader, then I think performance reviews can be useful. I do think, however, that performance reviews are more dangerous at a start-up. The big difference between a big company and a small company is that at bigco individuals don't matter as much (sorry to my friends who work in bigcos but it's true). But at smallco and start-ups, individuals make all the difference. Performance reviews done badly can set people off, alienate them from each other or the company, and fracture rather than help to fuse the team. In a start-up that's not just bad, it's disastrous.
The thing to be clear about in a start-up, if you are going to do performance reviews, is why. There's only one good reason I know of to do them in a small company -- as a way to mentor people on how they can work better individually and as a team.
And the worst mistake I know of (actually I believe this is a mistake for software teams in bigcos too) is to attach performance reviews directly to compensation. You can't mentor someone when they're thinking "I'm getting screwed on compensation because this bozo gave me a 5 when I should have gotten a 9." And nothing is more likely to fracture that fragile relationship between the individual, the team and the company.
Which raises another question: how can you keep performance reviews and compensation rewards separate, especially when for many companies they're done at the same time of year? I have two rules of thumb I use to keep them separate:
- Decide on compensation changes before working on performance reviews;
- Never adjust compensation changes after doing performance reviews.
It's sort of a Karate Kid thing: rule #2 is "see rule #1."
Does that sound crazy? I've found it works. Compensation changes are based on what's fair for each individual as a result of team success (and company success) and the person's relative position in the team. Performance reviews are based on the key messages you want to communicate to individuals about what matters, what doesn't, where they're doing well and where and how they can improve.
Here's an example: I had an engineer who was working for me who was underpaid relative to his position in the team. He wasn't underperforming, although he wasn't overperforming either. In terms of performance if we did a stack-ranking (in a high-performing small team) he was in the lower 25%, but in terms of percentage raise he ended up at the top.
His performance review was fair (and received as fair) because it correctly reflected areas he needed work.
His raise was fair (and received positively by him) because it just brought him in line with where he should be relative to his position in the team. And I didn't have to worry about other team members finding out about his percentage raise, because I knew it was fair and I could defend it (and they received fair raises too).
In this process, he learned that performance reviews and compensation are two separate things, and that helps him (I believe) receive the performance messages more clearly and openly, now and in the future.
The key word here is trust. Trust is established by treating people fairly, and not creating over-complicated or unnatural performance rating systems that attempt to justify compensation decisions. If performance reviews are really honest mentoring efforts, then they can be an asset in any size team.
