Simulation And Application Of Lean Six Sigma In Business Process: A Case Study In Precision Tooling Service Company

Abstract

In the service industry, one of the biggest problems that enterprises are facing at the moment is the long processing time between stages. Stages that are likely to be affected by long processing time are inventory process, manufacturing process… especially the sales process. In the sales process, from the customer point of view, the time when customers start to contact the company until they finally receive the products usually takes longer than what they expect. It can lead to some concerns in terms of delaying orders, which results in customer dissatisfaction. Therefore, in order to tackle the unwanted consequence of long processing time, many methods such as lean, six sigma, simulation, … are widely applied nowadays. This thesis is aimed to use the applications of simulation, DMAIC method, and some lean tools, namely the VSM, SIPOC, Project charter. It is hoped the case study can improve the situation at Van Phu Thanh’s company, which is a precision tooling service company.
