The use of earned value management for initiating directive project control decisions: a case study
South African Journal of Industrial Engineering, 2016 With large infrastructure backlogs in Africa, well-controlled projects will play a significant role in African infrastructure development. In this paper, the monitoring and/or directive use of Earned Value Management (EVM) is investigated and linked to ...
