Dear Mr Vinayak Patil,

You have presented a simple, yet very effective Bell Curve.

I am sure many would stand to get benefitted by it.

One possibility extends to cover the STAR performers separately.

In this, 3,3 category opens up a new column( column F as per your attached Xl).

The total commitment to the Management will be limited to the 5% for Column F

Consequently the allotted percentages in D & E

(OR even in B,C,D,E )would stand reduced accordingly.

The changes as above would provide a perfect Normal Distribution curve theoretically.

Practically this would be useful to retain the STAR performers as they stand out

from the rest. The Management would be very happy to retain them.

I have one more suggestion to consider the following values for the given Bell Curve.

Column D -- 50 to 60 %.

Column E -- 15 to 20 %.

This would ensure that in the event of Management sanctioning Maximum as proposed,

then the total would add to 100% considering Maximum in all the four.

thank you again for your excellent post,

V.Raghunathan

Dear Sir,
Humbly I would like to inform you that, the attached bell curve sheet was not prepared by me. Sorry, I did not mention the source while uploading the same, the source was internet itself.
I used the same in my organization so, shared for ready reference & thanks for your valuable suggestion.

Your request would sound better if reworded as follows. "Please could some one explain to me how the ratings 1.1,1.2 etc. are developed?"
It is based on marks obtained.
Example classification is as below:
20-40=4=Needs Improvement
40-60=3=Average
60-80=2=Good
80-100=1=Very Good
40=3
41=3.05
42=3.1
43=3.15
44=3.2
45=3.25
46=3.3
47=3.35
48=3.4
49=3.45
50=3.5
51=3.55
52=3.6
53=3.65
54=3.7
55=3.75
56=3.8
57=3.85
58=3.9
59=3.95
Please correct me if I have done it in wrong way.

please find attached snip for PMS Ranking example.
