“More is better!” Well, that’s not always the case when it comes to 360
degree review raters. In preparing to collect feedback from
peers, customers, supervisors, or direct reports, you might want
to hear from everyone.
Unfortunately, too many raters could lead to ratings “averaging out.”
That means two things:
1.
There might not be anything different between the
third person’s rating and the seventh's. They’ll probably be pretty similar.
2.
More raters bring the average scores to the middle.
It’ll be hard to see areas where you exceed or don’t meet expectations.
It’s always good to request feedback, but you’ll miss important feedback
or trends because of the averages. Instead, find the right number of raters so
the feedback is there with the benefit of multiple perspectives.
So what’s the right number?
·
1-2: With
such a low number of raters, the feedback is no longer anonymous. One skewed
rating could also be an outlier, but without other raters, you wouldn’t know if
that’s typical behavior or someone being severely subjective.
·
3-4: Here’s a
good sweet spot because if there is an extreme rater, the others provide the
balance. The group doesn’t get too big though, so the feedback is going to
better reflect performance.
·
5+: Raters
start to blur after five, and you start seeing the averaging effect. Plus, you
might also burn out your raters if they’re already filling out a number of 360
degree reviews for other employees.
