Simulation to Bridge the Gap Between Visual Management Theory and on-Site Applications

This study examines the effectiveness of Visual Management (VM), a Lean Construction tool, in reducing stress levels and improving efficiency in construction processes. Through a simulated floor plan modification exercise, we compare the performance of teams using traditional written instructions versus those employing VM techniques. The research aims to quantify the time savings and accuracy improvements achieved by using visual tools such as shadow marking and colour coding. The methodology involves a crossover design with a total of 66 students, participating in both Lean and Non-Lean conditions across two rounds. Performance metrics include accuracy (the number of tasks accurately completed) and stress levels. Our findings demonstrate that VM significantly reduces task completion time, enhances accuracy, and decreases stress levels in a simulated construction-like environment. This study contributes to the growing body of evidence supporting the implementation of Lean principles, particularly VM, in construction projects to enhance productivity and reduce waste.
