Hi!
What you attached is not a "tool". It is simply a write up on the 360 degree evaluation framework.
I have always stated in this forum, the 360 degree, 90 degree, etc. are simply frameworks on how to implement an appraisal in the company. You still need a performance evaluation tool to measure an employee's performance.
The BSC (Balance Score Card) is an example of a performance evaluation tool. If you implement a BSC in a company and require all the work contacts (superior, colleague, customer, staff) of an employee, then you implement the BSC using the 360 degree evaluation framework. If only the superior will evaluate, then you use the BSC in a 90 degree evaluation framework.
The 360 degree framework is an ideal method of doing appraisals. But, it is difficult to process and justify legally because the "appropriate weight assignment" for each evaluator (e.g. superior vs. customer = weight of 50% each) can be questionable/ debatable. Moreover, it needs more time to administer --- hence nearly impossible for huge organizations with a few thousand employees, but with a few HR staff and small HR group/ department.
