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 that 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 (Balanced Scorecard) as a Performance Evaluation Tool
The BSC (Balanced Scorecard) 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.
Challenges of the 360-Degree Framework
The 360-degree framework is an ideal method of doing appraisals. However, 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 a small HR group/department.
Best regards.
