The DMAIC theory explains how to solves the problem in this case study.

1. Define (D) Define the scope and set objectives in project charter.

2. Measure (M) Measure the current state process map such as process steps, process time, lead time, WIP, etc from the work place

3. Analyze (A) Analyze current state, i.e. value and non-value added processes, bottleneck constraint and process efficiency.

4. Improve (I) Improve process by designing a future state map.

5. Control (C) Control and hold the gain with metrics to monitor results over time.
