There are many different approaches that organizations use to rate their employees and to determine promotions in the ranks. Some rely strictly on written evaluations that use a Likert scale measurement, along with a supporting narrative to rate their employees. Others use goal and achievement-based evaluation system. Others rely on oral presentations before a panel of evaluators. Others use multiple choice written examinations. Yet others use realistic scenario-based assessment center evaluation techniques.
Describe and assess the advantages and disadvantages of each of these approaches. Explain which one (or combination) of these approaches is the best, and why.
