Difference between KRA and KPI

Dear Friends and Seniors,
I have some question related with KRA and KPI.
1. Are they interlinked?
2. Can we set one KPI without having one’s KRA?
You are requested to provide some insight on this.

Rahul Sindhwani

My knowledge goes, KRA is Key Result Area, and KPI is Key performance index / indicator. With out KRA fixed at the beginning of the financial year, the KPI decided on the KRA .
For example you are fixing a KRA of 20% more profit to be achieved, and KPI could be 10% from the 'new customer' and another 10% from the 'existing customer'. Another example is, on cost reduction of 20% KRA fixed at the beginning of the year, out of which the performer KPI could be fixed 10% from existing supplier, and 10 from the new supplier.

Dear Rahul,
I have uploaded two videos on Youtube. One is on the difference between KPI and KRA and another is on PMS. Click the following links to refer those videos:

You may go through both the videos to update yourself on these concepts.
