The second stage is Measure, where activity in this stage is collecting the data on the number of problems, types of problems, mapping processes, cost impacts, and time impacts. The third stage is to Analyze, where activity in this stage is conduct analyzing the root causes using a fishbone diagram from the 4M side (Manpower, Method, Measurement, Material, and Machine). The fourth stage is Improve, where activity in this stage is to determine the right improvement to the root causes of problems. In this paper, there are 2 types of improvements: existing improvements for each of the root causes of the problem and 3 proposal improvements to solve the root causes of the problem as a whole. The fifth or final stage is Control, where activity in this stage is all improvements controlling and written in the implementation plan regarding the improvement schedule.
