Achievement 2

Spent around 4.5 hours to facilitate Management team and on-site operator to perform a Gemba Kaizen in semi assembly room, brainstorm layout redesign to reduce transportation/motion waste and implement kanban system to eliminate the problem of overproduction.

Tools Utilized: Gemba Kaizen, 5S, Kitting and tooling at assembly point, Kanban system, Yamazumi chart plotting

Result: i)   All the overproduced part, extra tools and jigs including table and trolley was
                 return to store and pass to area of shortage. Originally "small" assembly area in
                 the end become spacious
            ii)  Only 1 day piece part and tools was ready in the area (Just-In-Time) to prevent 
                 overproduction, while progress of production can be visually monitor from time to
                 time (Visual management)
            iii) Actual daily output was plotted against daily planned output (Yamazumi chart) so 
                 that the bottleneck station can be identified and have a lean project on it
            iv) The inventory level reduced from 1 week to only 1 day inventory, so that any theft
                 or left out assembly part quality issue can be detected immediately
            v)  The tools and piece part needed was organized at point of use- transportation 
                  reduced from 219 steps to 121 steps per day (45% improvement)
