1. Make full use of the bottleneck. Find a way to maximize the bottleneck utilization to achieve efficient and effective output. For example, many jobs in a process will stop at lunch time, but if a process is a bottleneck, the job should consider using lunch time, and the bottleneck must not be idle.

2. Bottleneck is an absolute priority. The effective use of bottlenecks is the most important, and everything else is secondary.

3. Improve the bottleneck ability. That is, trying to improve the available working hours of the bottleneck, including increasing its production capacity.

4. When the bottleneck is no longer a bottleneck, find a new bottleneck and repeat the above steps. With the improvement of the effective utilization rate of bottlenecks, bottlenecks may no longer be bottlenecks, while another process becomes bottlenecks. In this case, the focus of the work should be shifted to the new process bottleneck in time.
