As a point of departure, this research provides a historical analysis of a non-systemic management approach - Business Process Reengineering (BPR) and several uni-demensional hard and soft systems approaches and their contributions to the emergence and development of CST. It is argued that, given the messy and ill-structured problems that emerge as a result of the implementation of Performance Management Systems (PMS) at Telkom, a pluralist problem solving methodology such as TSI is the appropriate methodology applicable to the problem under concern.enPerformance.Telkom (Firm).Organizational change.Industrial management.Theses--Leadership and management.Thesis
