In order to carry out this study, data were collected using questionnaires, interviews and documentary analysis and were quantitatively and analyzed with the help of SPSS software programme.Total respondents were 105; 25 leaders and 80 non leaders and had been obtained through simple random, stratified random and purposive sampling procedures. The study revealed that performance appraisal at TANESCO was less effective due to lack of knowledge about the appraisal system, low top management support, ineffective performance feedback mechanism in the Performance Appraisal process, However Performance Appraisal was crucial in addressing institutional as well as staff member needs if effectively regularly and timely done in a participatory manner. From the study it is recommended that; the management through the human resource department should organize an elaborate training program for both managers (appraisers) and employees (appraised) on the performance appraisal process to include appreciation of the concepts and objectives, setting of performance standards, and also keeping and maintaining accurate records of employee’s performance. The performance appraisal system should be redesigned to embrace a proper communication channel through performance interview for feedback on the performance appraisal results. Management should ensure good performance is rewarded. Furthermore, the study recommends further studies to investigate and determine the linkage between Open Performance and Review Appraisal System (OPRAS) in TANESCO and the other public service Institutions.enPerformance appraisalTanzania Electric Supply Company LimitedThesis
