Hi, the term 360m degree represents a full circle of feedback from all angles. Other names are multi-rater, multi-source, full-circle, group performance review, 180 degrees and, finally, the 720 degrees. Some Companies or organizations apply a 720-degree approach which provides for two rounds of feedback (a pre- and post-test) or a feedback approach which is done again after nine to twelve months. The performance appraisal can be on an individual basis, a multi-rater process—either from an online assessment or through the more involved structured interview process. Performance appraisals are done by companies to help to review the performance of the employees, their strengths, weaknesses and accomplishments during the year. Performance appraisal allows deciding the goals, objectives and the desired performance standards for the employee for the upcoming year. There is no comprehensive formula for doing so. The overall rating is based on a number of factors like the extent of goals achieved, the overall performance of the employee, his competencies etc.
