Relative Importance Index in Ranking Performance Management Practices Towards Organizational Performance

Deficiencies in the implementation of water supply projects, inadequate water infrastructure management, customer dissatisfaction with water services, and persistent water production shortages, are performance problems that affect water service delivery. This paper aimed to identify the performance management practices affecting the performance of Mtwara Urban Water Supply and Sanitation Authority by using the Relative Importance Index (RII) method. The method used for data collection was a questionnaire. A sample of 64respondents was drawn from the study population using a simple random sampling technique. Performance management practices were ranked using the responses acquired from respondents. The calculation of the Relative Relevance Index (RII) showed the ranking level of relevance. The finding showed that goal setting was ranked first (RII = 0.85), performance appraisal of employees was ranked second (RII = 0.83), measurement of performance ranked third (RII = 0.82), and target alignment with strategic objective (RII = 0.81). This study has an important contribution to guide managers and Human Resources professionals in designing and implementing more performance management strategies that align with organizational goals for effective water service delivery
