One review to rule them all

Performance reviews based on results may not work for every job. For example, evaluating a teacher based solely on student test scores, since environmental factors such as poverty or lack of support may also play a part.

It is vital to use only one type of review system to create fairness for all. If judging on results doesn’t work, an organization could try a behaviour-based system but revise it so that it doesn’t favour employees working in the office.
