The probability of receiving reliable feedback increases dramatically as you increase the number of evaluators and evaluation perspectives. Express the key competencies as attributes against which participants can be assessed. Select who to conduct the evaluation. Typically a number of peers, customers, subordinates, if applicable, and the manager are selected. Compile the results.
Feedback is kept confidential.
Provide feedback to the individual. Create an action plan to improve the individual's performance. One important factor for the success of a 360 degree performance assessment is to ensure that the right people are selected to provide the feedback. Both critics and supporters of the individual should be selected. Another key to success avoiding punishment for bad results.
