Measuring Performance 137 Check the Box: The Trait System You've been rated by them. You've probably used them to rate others. The most common evaluation system is the "trait" format, in which a series of traits are listed in the left margin, and each is meas- ured against a scale from unsatisfactory to excellent. Heads Up! Evaluating team performance is not a substitute for evaluating individual performance. They are both important. Members should be held accountable for their own actions as well as their part in the collaborative efforts of the team. This system seems on the surface to be simple to administer and easy to understand, but it's loaded with problems. Leaders tend to fall into the following traps when rating members on a trait system: · Central tendency.Rather than carefully evaluate each trait, it's much easier to rate a trait as average or close to average (the central rating). · The halo effect.Some managers believe that one trait is so impressive they rate all traits highly.
