- ItemApplication of lean tools in rolling stock procurement supply chain management(Stellenbosch : Stellenbosch University, 2018-03) Ekene, Nicholas Umeh; Fourie, Cornelius J.; Matope, Stephen; Stellenbosch University. Faculty of Engineering. Dept. of Industrial Engineering.ENGLISH ABSTRACT: The main aim of this research study was an investigation of applicable lean tools in rolling stock procurement supply chain management (SCM). Lean principles resonate from the manufacturing environment while rolling stock procurement SCM is a typical example of the non-manufacturing environment. Hence a variance in applicable tools is apparent. The case study of the research was studied and analysed. The procedure adopted for measurement and analysis of the case study (rolling stock procurement SCM) began with mapping the process areas. This was performed through a type of lean tool known as value stream mapping. After the SCM mapping, the lean waste in the SCM was identified through waste analysis. During analysis, it was discovered that the bidding process holds the highest area of waste. Following this finding, the bidding process was evaluated, upon which lean tools for waste reduction are prescribed. From the findings obtained in the measurement and analysis step, mapping of the future state was carried out. Based on the mapping of the future state of the supply chain, relevant performance metrics are recommended for a periodic check. Limitations, as well as assumptions encountered during the research study, are also discussed. The study conclusion is presented in the form of answers to the research questions. Some of the major waste discovered in the bidding process includes poor communication between bidding team and end user and difficulty in sourcing for potential suppliers. The recommendations put forward in this research project are to strategically reform the bidding process by making required changes to tender documents, standardising the procurement SCM process and improving the communication culture between suppliers and SCM.
