360degree feedback (sometimes called 360 feedback) is feedback given to an employee from multiple sources as a form of performance management. Wondering how to present feedback to your boss?Learn about the research behind 15Five's revolutionary 360° Best-Self Review, which includes a Self, Manager, Peer, and Upward Reviews. I was fired as a result of a 360 review that I think went down terribly. Need to know if it's as screwed up as it sounds. A 360 performance review measures employee performance typically using feedback from six to 12 people. It also includes an employee self-evaluation. Despite how it was pitched, I was only asked to complete a review for my closest co-worker. Performance in preference to development purposes has not been clarified in the literature. 360 review feedback forms should be kept relatively short and simple, as employees will likely be asked to fill out several with each cycle.
