ABSTRACT
When making improvements to reduce the frequency of minor stoppages, be sure to observe the following key points.
Make a new study of the structure, mechanisms, and operational principles of the target equipment.
Do a cleaning inspection on all related equipment parts.
Carefully observe the minor stoppage phenomena.
Look at causes as mechanisms (or as hypotheses).
Verify causal mechanisms.
Establish improvement policies.
Repeat the plan-do-check cycle in actual improvement measures.
