I've just commented on an interesting post from one of our competitors on how many questions you should have in 360 degree appraisals. The post has interesting feedback on how long people take to complete questions.
My comment was
"Mark,
Thanks for this - the stats are really useful. We share your avoidance of “quick and dirty” solutions. I guess the really interesting thing for me is whether the 19 minutes spent answering the HR questions gave better feedback to work with than the 14 minutes people spent answering the engineering company questions. We generally find that the narrative feedback is more useful than rating scale scores and use that insight when trying to gauge “how many” questions are needed."I strongly believe that the rating feedback serves the narrative feedback. And "how long does it take to complete" is less important than "how rich is the feedback we get". I'd rather have 10 good narrative comments than 20 rating scales. Great stats though!
