1.1       Background of Study

Performance appraisal is a tool for identification of deficiencies which point out the weaknesses of employees and spot the areas where development efforts are needed in the organization. Performance appraisal also plays a key role to measure the employee’s performance and help the organization to check the progress towards the desired goals and objectives (Ijbmr, 2012). Now organizations are using performance appraisal as a strategic approach by coordinating the human resource functions and business policies. They are focuses on it as it is a broad term that covering number of activities like examines employees, improve abilities, maintain performance and allocate rewards (Fakharyan, Jalilv and Dini, 2012). Performance appraisal help aligns individual goals and objectives with the organization goals. The system engages, motivates employees and thereby directs them toward achieving the strategic ‘goals of the organization (Verhulp, 2006).

The fact remains that good organization performance refers to the employee’s performance, satisfactory performance of employees does not happen automatically. Managerial standards, Knowledge and Skill, Commitment and Performance appraisals have effect on employee’s productivity. According to Lillian and Sitati (2011) opined that the history of performance appraisal is quite brief. Performances appraisal roots can be traced in the early 20th century to Taylor’s pioneering time and motion studies. The performance appraisal system start in practiced mainly in the 1940s and with the help of this system, merit rating was used for the first time near the Second World War as a method of justifying an employee’s wages. There are number of government establishment in Nigeria using the performance management system for making their employee’s productivity better because it leads to achieve organizational performance. However performance appraisal is very important process but it deemed to be the “weak point” of managing human force (Pulakios, 2009). Therefore performance appraisal is important to manage employee’s work effectively.

According to Armstrong (2001) who found performance as behavior the way in which organization’s teams and individuals get work done. (Mooney, 2009) suggested that performance is not only related to results but it also relates with activities and behaviors of employees that they adopted to achieve their given goals. Performance appraisal is the systematic evacuation of employees according to their job and potential development. (Pinar Güngör, 2011) says “Motivation is the ability of person to modify his/her behavior”. Motivation is a driven force that leads and directed a person toward some specific goals.

Performance appraisal has been helping an employee knowing what is expected of him and remain focused with the help of the supervisor, tells them how well they have done that motivates the employees toward the good performance(Casio, 2003). Performance management system is the process that strongly involves assurance and participation of employees within the organization and that determine the organizational results. The evaluation system identifies the gap of performance (if any). The feedback system tells the employee about the quality of his or her work performance (NCN report HR Department’, 2010). Performance appraisal can enhance the benefits for the organization, but apparently it is not delivering the benefits in many cases (John Mooney, 2009). Most of the organizations usually include performance appraisal they cannot take the benefits from that because there lay a huge difference between the anticipations and experiences in the present system (Elverfeldt, 2005). Importantly, most employees believe that the major outcome of performance appraisal 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. This matrix of tasks makes the job of Nigerian Custom Services is highly demanding, thereby requiring an effective performance evaluation system that will ginger higher motivation for enhanced job performance (Aslam, 2011).


1.2       Statement of the Problem

Performance appraisal has been criticized by people because approach like bureaucratic and top-down under the control of human resource managers. It was often backward looking, concentrating on what had gone wrong, rather than looking forward to future development needs. Performance appraisal schemes existed in isolation. There was little or no link between them and the needs of the business. It has been discovered that line managers have frequently rejected performance appraisal schemes as being time consuming and irrelevant. Employees have resented the superficial nature with which appraisals have been conducted by managers who lack the skills required, tend to be biased and are simply going through the motions. Additionally, situations may arise sometime 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 gap is the problem that occurs when performance does not meet the standards that are set by the organization. This calls to question the fairness of the appraisal system and its ability to effectively produce the desired outcomes. Performance appraisal believes to be a difficult and complex activity which is often not performed well by many organizations. It is quite understandable that the end result of this is that it produces exactly the opposite or have adverse effect to those intended.

Furtherance to the state of the problem, currently in Nigeria, it has seen in the public sector that general atmosphere of discontent pervading the entire labour panorama, which Nigeria Customs Service are not left out in the general state of disappointment and aggravation. 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. This situation has made it imperative for Nigerian workers to pay particular attention to human resource practices which have direct bearing on their financial rewards and social status. One of such human resource activities is performance appraisal, which is the focus of this study.

However, the study focuses on how performance appraisal used in an organization to increase employees’ productivity.

1.7       Significance of the Study

In the light of the foregoing, this study set out to investigate how performance appraisal that is anchored mainly on one job component, that is, research output, affects the motivation and overall performance of Nigeria Customs Service.
