Ask a Manager

Performance evaluations seem to inspire a special sort of dread — not just among employees but also for the managers who have to write them. Here are six mistakes managers commonly make in the process.

1. Procrastinating. Putting off a performance evaluation sends a horrible message, by signaling that the manager doesn’t care about the employee’s professional development.

2. Not being direct about problem areas. Of course, nothing in a performance evaluation should be a surprise, because the manager should have been giving feedback all year, but bad managers shy away from discussing problem areas, and this often carries over to formal evaluations as well. Sure, addressing problems can be uncomfortable, but you shouldn’t be a manager if you’re not willing to meet this obligation.

3. Not being specific enough. Managers often write reviews in generalities, both when praising and when offering criticism — for instance, writing, “You’re slow in getting your assignments done” rather than, “You turned the quarterly report in late during two of the four reporting periods.” It’s true of praise too; you could say, “You did a great job with the new inventory system,” but it’s more effective to say, “Your revamping of the inventory system has saved the company money and I’ve heard several people comment about how much easier you’ve made it to find the supplies they need.”

4. Not paying attention to the overall picture. I’ve seen managers write lukewarm evaluations for employees I know they love and would devastated to lose, and I’ve seen weirdly positive evaluations for employees who need to make major improvements. Managers need to pay attention to the overall message and make sure that the sum of the parts adds up to the correct whole.

5. Focusing only on recent history rather than the entire evaluation period. Managers should resist the temptation to be overly influenced by recent events; the evaluation is (in most cases) for the whole year, not just the last few months.

6. Not getting feedback from others. Managers should be aware that they only see part of the employee’s performance, and by seeking feedback in confidence from others who work closely with the person, they may learn things, both good and bad, that are useful to know.
