Bell-curve as performance appraisal
The Bell curve, also known as the Gaussian distribution or normal distribution, is a statistical concept used to represent a range of values distributed around a central point, with most values falling close to that point and fewer values falling farther away. In the context of employee performance appraisal, companies use the Bell curve to compare an employee's performance with that of their peers to evaluate it. The idea behind this approach is to assign a fixed percentage of employees to different performance categories based on the distribution of their performance scores relative to their colleagues. For example, a company might use a Bell curve approach to assign performance ratings as follows: Top performers: 10-15% of employees Above average performers: 25-30% of employees Average performers: 40-50% of employees Below average performers: 10-15% of employees Poor performers: 5-10% of employees Note that I created the above allocations without any study or proposal for anyone...
