Why do we do 360 -
1. Get an overall understanding of the individual from all stakeholders and peers
2. Remove single person rater bias
So I would not suggest asking peers or rate on goals or targets...instead,
Would suggest you to take 360 feedback on Competencies (or Company values displayed by the individual as a proxy) and add a generic question on Overall rating of the individual. Give ample opportunities to type comments and remarks...these help in understanding an overall perspective of the individual.
