Dissertation (MA Public Administration)This study is about the practical challenges encountered by DEDs on performance in LGAs in Tanzania. The study was conducted at Singida District. The study involves a sample of 80 respondents. This sample has been derived by applying purposive, stratified and random sampling technique. The methods which were used to collect data are interviewing, questionnaire, discussion, documentary review and observation. Purposely, the study objectives were analysed based on the study title. The data collected were analyzed through Statistical Package of Social Science (SPSS), version 16.0, whereby sum, frequencies and percentages were calculated as well as creating the tables and figures. Apart from that, the study shows that there are different problems encountered by DEDs on performance in LGAs, these include; delay or inability to submit requirements returns or statement, lack of understanding clear lines of authorities and responsibility for management. Also, the study suggested that, various measures can be used to solve challenges encountered by DEDs on performance in LGAs. The strategies include the use of professional and technical knowledge, capacity building for staff, decentralisation, and introduction of the existing training programme for civil servants, and involve people in decision making. Generally, this study concludes that, various approaches and principles of administration must be relevant to LGAs for effective development. This is because in third world countries, LGAs reform is important through D by D. Also, this study is very useful as it will be serving as a reference for as further studies and it is recommended that relevant study should be carried all over the country to study the magnitude on how they put into practice effective and sustainable measures.
