It is hard enough for us to assess our subordinates’ performance, but we must also try to improve it. No matter how well a subordinate has done his job, we can always find ways to suggest improvement, something about which a manager need not feel embarrassed. Blessed with 20/20 hindsight, we can compare what the subordinate did against what he might have done, and the variance can tell both of us how to do things better in the future.
