Impact of lean tools selection: a simulation study of two assessment approaches

Abstract

As lean becomes more popular in various industries, the amount of available lean tools also increases. Selecting appropriate tools to be implemented to the right place at the right time becomes a challenge. Several methods have been developed to help, including some assessment-based approaches and value stream mapping. Creating a good ‘future state’ map requires solid knowledge and experiences. While assessment tools are available for inexperienced users, they often rely on static models or roadmaps that may not suit a variety of systems. This paper investigates the impact of using different selection methods of lean tools in improvement projects. A simulation study based on a real manufacturing system has been conducted for the comparison of effectiveness of two assessment-based approaches. The results show that when lean tools are selected by an adaptive assessment approach, the improvement progresses better than using a static roadmap approach.
