360 degree feedback is the feedback that comes from multiple sources. The sources are normally an employee’s immediate work circle.
It includes direct reports, colleagues and line managers. In most cases, 360 degree feedback involves a self evaluation. Some companies choose to include external parties, like clients and suppliers, but it is not always the case.
A 360 review is an evaluation process carried out by a team in order to get each of the team members to improve. It should not be a performance review, even though some use the word performance in the title. The feedback in a 360 review is about spotting strengths, and possibly weaknesses, which are used to plan personal growth and map specific paths for development.
