D. Tech. Marketing, Logistics and Sport Management / This study explores supply chain costs in the South African mobile phone industry, which then leads to the development of a supply chain cost-reduction framework for this industry. The knowledge generated from this study should assist South African mobile phone companies to reduce their supply chain costs. On the other hand, this study should also assist regulating authorities (the Department of Communication and The Independent Communications Authority of South Africa [ICASA]) to gain insight into the cost drivers in the mobile phone supply chain and the contributing factors to high call tariffs in South Africa. It should also inform appropriate and adequate mobile telecommunication policies. The purpose of this study is to explore supply chain costs in the South African mobile phone industry, and to develop a supply chain cost-reduction framework for the South African mobile phone industry.
