The bell curve is basically a gaussian distribution graph and is used extensively in organisations for providing performance rating of employees. That is how you get the hikes people!! This diagram explains it is the most simple way. It puts the bottom 5% to 10% in the low performer category and about the next 70% as the average performers. The rest are top performers. Even here, the top 5% would be the stars or best in class and these are the ones who walk away with the promotions. What happens to the bottom ones? Well, they could be coached, out on performance improvement plans, moved to other teams where they may be a better fit or even terminated. It depends on the organisation policy.

- Most managers add employees to the top bracket by rotation. So hang in there and bide your time.
- Nobody talks about the bell curve explicitly. It is almost a taboo word. So don’t go around asking for cut off percentages 🙂
- The managers are given a lump sum, a figure to be distributed as hiked amounts to team members. This needs to be as per the bell curve. However, they can play with the figures. If you are expecting a high raise, do tell your boss. Then remind them. Then remind them again!
- If you got an average rating or an average hike and were told it was due to the bell curve, accept it. Not much you can do about it. Continue your good work and focus towards a higher rating for the next cycle.

I did not get a thing! And I guess you are so intelligent to understand something complex like this! Do you manage to write these posts in one go?
Hain!!!???? Kyun, I wrote itna kharab? This has got nothing to do with intelligence. Just knowing some things. And yes, I usually write these posts at one go… in 30 to 40 minutes!
Thankfully, I didnt had the bell curve appraisal system at my office but husband had in his earlier organization and he was not too happy about it!
You lucky girl you!! I can only empathise with your hubby. Hoping that this year, he will be happy!
Brief but interesting. I think bottom 10% should not be forced. May be there is a grading of satisfactory or unsatisfactory. This should be a careful assessment by a superior and his superior. Any person rated as unsatisfactory needs a good amount of training and coaching. If in one year somebody is rated as unsatisfactory, at least a year must be spent on him in training and coaching. Any well set organization should recruit a person only when they can give a chance for at least two years. Any error in recruitment is to the account of recruitment team. They have to take responsibility of training and coaching.
I agree with you completely. Given that the bell curve grading system is relative, one needs to remember that the so called low performers are in that bracket by comparison. They could be good at their job, just having someone slightly better does not make you an incompetent professional. Unfortunately, that is how it is perceived. Coaching, training and finding the right fit is extremely important for this bracket!
I’m off the opinion that the appraisal system in most corporates in India needs an overhaul, Ankita! Great topic and one that needs a lot more focus within the corporate world.
Thanks Corinne. I agree it needs an overhaul! A good thing is that organisations are waking up to this reality and many are adopting other techniques…
Wow! That is quite a lot of information for me!! I never knew bell curves were so important even in things like promotion and hikes. Thanks!
