Remember that when it comes to assessing people, the two biggest mistakes you can make are being overconfident in your assessment and failing to get in sync on it. If you believe that something is true about someone, it’s your responsibility to make sure that it is true and that the person you’re assessing agrees. Of course, in some cases it may be impossible to get in sync (if you believe that someone was dishonest and they insist that they weren’t, for example), but in a culture of truth and transparency it is an obligation to share your view and let others express theirs.

Get in sync on assessments in a nonhierarchical way. In most organizations, evaluations run in only one direction, with the manager assessing the managee. The managee typically disagrees with the assessment, especially if it is worse than his or her self-assessment, because most people believe themselves to be better than they really are. Managees also have opinions about managers that they wouldn’t dare bring up in most companies, so misunderstandings and resentments fester. This perverse behavior undermines the effectiveness of the environment and the relationships between people. It can be avoided by getting in sync in a high-quality way. Your reports have to believe that you’re not their enemy—that your sole goal is to move toward the truth; that you are trying to help them and so will not enable their self-deception, perpetuate a lie, or let them off the hook. This has to be done in an honest and transparent way, because if someone believes they are being pigeonholed unfairly the process won’t work. As equal partners, it is up to both of you to get to the truth. When each party is an equal participant, no one can feel cornered.
