Hi Drishti,
Framing a Performance Appraisal Policy
Framing a performance appraisal policy or system takes more than just the information or performance appraisal forms. Since you would be evaluating performance for various positions, you should first know what to evaluate. In simpler terms, the detailed job description for each role should be drafted. There may be cases where a person at a particular position/designation might be carrying out roles not specifically mentioned in their job description. There should be open-ended questions that would help the person describe any extra job roles that they might be performing.
Steps to Develop a Performance Appraisal System
You should first find out, depending on your industry and employee strength, what method of performance appraisal you would be using - 360 degrees, 180 degrees, etc. Determine who would be evaluating whom. According to such details, you should be forming appraisal forms and their questions. Also, you should determine if you want to use the same appraisal forms for all departments or customize them as per the department.
In addition, there should be a proper understanding so that the appraisal forms are not filled with ambiguous words like "good" and "excellent," which can be interpreted differently by different people. Instead, use concrete terms or numbers that would have the same meaning for all.
As suggested by the experts, you should consider outsourcing the performance appraisal task, at least for this year, given the time constraint provided by your management. In the process, you can also learn the procedures being followed and their significance to develop a performance appraisal policy for your firm starting next year.
Wishing you good luck.
