There have been different kinds of research carried out on project management (PM) practices addressing performance gaps in developmental projects. The Project Management Institute (PMI) has developed the Project Management Body of Knowledge (PMBOK) as the best practices in managing projects over the past decades. The main aim of this paper is to assess the project management practices of aid/development projects: A case of Gudina Tumsa foundation. Finding out which practices they are using, is these practices were based on the ten knowledge areas. The descriptive research design was used in the study and the census survey was used because the participants were few. Both the quantitative and qualitative research approach was used the study. The data obtained was analysed using mean and percentages the knowledge areas were further putted in SD. The research instrument used for this paper is both primary and secondary data, Primary data was collected using a questionnaire and a semi-structured interview secondary data was used from different documents from the organization and other book and journals. The questionnaire was distributed to all the members in the organization out of 27 individuals 23 (85 %) of them properly filled and return it. The researcher interviewed the program officer and top managers, and some board members of the organization. From the finding, it can be understood that some of the knowledge areas were properly managed and used but some have not been properly managed although they have managed some of them it was traditionally. This paper suggests that the organization should implement different projects based on project management knowledge areas and using each knowledge area processes to formally implement it.
