CHAPTER ONE
BACKGROUND OF THE STUDY
 PA can improve motivation and performance, but if used inappropriately, it can have disastrous effects (Fisher et al, 2003). For PA to be effective, it must of necessity be anchored on the performance criteria that have been outlined for the job. Riggio (2003) describes performance criteria as the means for determining successful or unsuccessful job performance. They are one of the products of a detailed job analysis. Performance criteria spell out the specific elements of a job and make it easier to develop the means of assessing levels of successful or unsuccessful job performance. It can thus be inferred that an appraisal system not hinged on this all important criteria, can neither be appropriate nor fair, particularly to the employee, whose performance is being evaluated. In fact, some key points in the arguments of those opposed to performance appraisal is that, most of the time, wrong things are rated and the wrong methods used (Deming, 1986; Gilliland and Langdon, 1998).PERFORMANCE APPRAISAL
Situations arise whereby only some selected job elements are evaluated or given preference or higher points above other job elements in which the employee was equally engaged during the review period. This calls to
question the fairness of the appraisal system and its ability to effectively produce the desired outcomes. Mickerney (1995) underscored the intricacy of PA by describing it as a difficult and complex activity which is often not performed well by many organizations. The end result of this is that it produces exactly the opposite effect to those intended (Coleman, 1995).
1.2 STATEMENT OF THE PROBLEM
In Nigeria today, the general state of poverty makes economic reward a very important reason why people go out to work, thereby making money to rank highly as a critical motivator (Muo, 2007).This situation has made it imperative for Nigerian workers to pay particular attention to human resource (HR) practices which have direct bearing on their financial rewards and social status. One of such HR activities is performance appraisal (PA), which is the focus of this study.
A major outcome of PA is promotion and its attendant increase in financial benefits plus enhanced professional and social status (Tessema and Soeters, 2006; Shahzad, Bashir and Ramay, 2008). Performance appraisal outcomes tend to have high motivational impact and are a major determinant of employee performance.
It must be emphasized that an effective performance appraisal system is one that takes cognizance of all the components of an employee’s job performance, and does not focus on selected ones.
