Rater errors

Consultant Marcus Buckingham and executive Ashley Goodall, reporting on a large-scale Deloitte performance management survey on Harvard Business Review, said, contrary to the assumptions underlying performance rating, the rating mainly measured the unique rating tendencies of the rater and thus reveals more about the rater than about the person who is rated. They referred to this as the idiosyncratic rater effect. In view of this effect, they advocate a radically different approach to performance management. In their scenario, 360-degree feedback and similar time-intensive exercises are replaced by team leaders' "performance snapshots" that focus on what they would do with each team member rather than what they think of that individual, and yearly appraisals of past performance are replaced by weekly check-ins among team leader and team member, preferably initiated by the team member, that focus on current and upcoming work.
