The research question this paper is trying to answer is: “What are the parameters that make up the conceptual model for PMM in the SA power sector?” The study is based on a literature review. The authors reviewed the relevant journals to search for key parameters for measuring PMM. The study proposes a conceptual model for measuring PMM in the SA’s power sector. The focus of this paper was limited to the peer reviewed articles and journals.
