In this study, the effect of performance reviews/appraisals and its relationship on HR decision making has been investigated. In order to test this theory, I used random sampling of 10 different data reports related to the pros and cons HR are faced with concerning performance reviews. Majority companies are reconsidering performance reviews therefore requiring thorough evaluation using outside consultants. Other companies find them a waste of time and do not do them because they are not done correctly. I was able to use data evaluation of decision theory and quantitative data collection through secondary data using public documents for this research
