Performance Appraisal System In Banking Industry

Hello Everyone,
I need to know how to develop performance appraisal system in the banking industry ? A bank has several Branches and different types of employees. As well as Head Office also has different kind of divisions with different employees including technical people. So how could a HR Profession assess their performance ?
If anyone has sample performance appraisal form for banking industry then please share. Discussion over here regarding it would be highly appreciated.
Thanks.

Hi!
I was part of the team that implemented the new appraisal system in a very large bank in the Middle East last year. And, my company has its own appraisal system that is even superior to the system that this bank implemented.
We can help you set up our appraisal system in your bank. We can also train your employees and HR staff on how to implement it.
