Dissertation (MA Public Administration)This study sought to assess the factors motivating employee's performance in the delivery of public services, and the impact on socio economic development using a case study of the Ministry for State President Office Public Service and Good Governance – Zanzibar (PO-PSGG). Both qualitative and quantitative research approaches were used and a sample of 43 respondents was taken, where 36 were the lower level employees, 3 were the managers, and 4 were the human resource officers. The study used questionnaires, and documentary review to elicit information from the sample, and data were analyzed through Statistical Package for Social Science (SPSS) Software Version 16.0. The findings were presented through description, tables and charts. The findings have revealed that, there was lack of understanding of even the term motivation to many public servants, in the Ministry for State President Office Public Service and Good Governance – Zanzibar (PO-PSGG), the current motivation level of the staffs was not satisfactory, the upper level staffs were always reluctant to give support to the research works, and that motivation packages employed by the Ministry did not affect the staff performance. This implied that management in the Ministry had to understand that education to staffs was necessary, so as to sensitize them. In order to solve the problem, the study came up with various recommendations like engaging more in social incentives, and engaging in satisfying the needs at the lower level as opposed to those at the upper level.
