Abstract: Water resources projects are essential to the population of Kwale County as well as being the pillar that support most projects in agriculture and fisheries sectors. In this study, the role of leaders such as coordination, change agent, conflict resolution and monitoring were analysed, and the findings showed how the leader’s roles influenced performance of projects and ultimately dictate the success of these projects. From the study, it was important for leaders to optimize performance measurement on projects so as to provide the basis for assessing how well projects progressed toward the planned and achieve targeted objectives.
