In the area of e-Government, knowledge plays a critical role in the development of e-Government transformation project management ontology, which aims at adopting and customizing the existing project management approaches accord- ing to the speciic challenges encountered in the e-Government environment. It is in this context that this chapter presents an ontological representation of the concepts of e-Government project management in one of the developing countries in southern Africa. The chapter further intends to collaborate in the excellence and productivity of the management of the e-Government project process. This will also enable the interoperability and knowledge reuse between all factors and stakeholders related with the implementation of such types of projects as a lesson for developing countries. The data was collected by use of an interview protocol or schedule, and the researcher interviewed relevant employees of the two ministries, the Ministry of Information Technology and the Ministry of Information and Communication. The data was then analyzed qualitatively to draw a model that the Zimbabwean government is adopting. Bongani Ngwenya Solusi University, Zimbabwe
