Abstract
The development of cost-integrated value-stream mapping (CVSM) as a lean assessment tool for identifying wastage in the production process is presented in this article. In conventional VSM, the time involved in various processes is mapped without tracking the accumulation of direct and indirect costs. In the proposed CVSM, the cost of production is also accounted for, along with the time domain of conventional value-stream mapping. The time investment of the cost is also incorporated in CVSM. Value-added and non-value-added costs can thus be easily recognised in the time scale This novel method helps to calculate the value addition in monetary terms, and thus the actual production cost of the processes is acknowledged accurately. Since the wastage is quantified in the cost domain, the processes in which lean tools need to be implemented can be identified. The details of establishing CVSM are presented along with a study of its implementation in a glove manufacturing industry.
Highlights
Fierce competition in globalised markets necessitates the adoption of manufacturing strategies that help to improve competitiveness

The development of cost-integrated value-stream mapping (CVSM) as a lean assessment tool for identifying wastage in the production process is presented in this article. In the proposed CVSM, the cost of production is accounted for, along with the time domain of conventional value-stream mapping. Since the wastage is quantified in the cost domain, the processes in which lean tools need to be implemented can be identified. Hierdie artikel bied die ontwikkeling van koste-geïntegreerde waardestroom kartering (CVSM) aan asn lenige assesseringstegniek om vermorsing in die vervaardigingsproses te identifiseer. Met konvensionele waardestroom kartering word die tyd benodig vir verskeie prosesse gekarteer sonder om tred te hou van die akkumulasie van direkte en indirekte onkostes. In die voorgestelde CVSM word die koste van produksie ook in ag geneem saam met die tyd domein van konvensionele waardestroom kartering. Die details om CVSM te vestig word aangebied saam metn gevallestudie inn handskoenvervaardigingsnywerheid
