Hello Pals,

A few days ago, I remember one of our team mates to have asked on the concept of Bell Curve and here is my brief answer to the same..

A bell curve is a theoretical dsitribution of scores across a given population. Applied to PMS, this means that the performance of the majority of a given population will tend to gravitate towards the center i.e., average while the extremes would comprise of either the poor performers or excellent ones. This simply means that you can't have 100% stars in a team; there has to be the so-so (average) guys and low performers. The curve is mostly used as a control mechanism.

Hope it helps ; )

Bell curve as a concept in PMS has been adopted by many organizations including Indian Companies to weed out low performers from the company. The supervisors and the HR managers appraise the performance of the employees and identify excellent-average-low(below average) performers and the pecentage is usually (20-70-10) or (10-80-10). This suggests that most of the employees (70-80%) fall in the average category. This is a relative concept in the sense that even if all employees working in the organization are very good yet among them some will be relatively better or worse than others.

Take my advice, don't get the bell curve in performance appraisals. It is one of the biggest blunders of the century and needs to stop now.

I assume you really are not aware of statistics when you asked that question. The bell curve will do more harm than good in your hand. So leave it and try the 5 point system.
