How should small and medium-sized enterprises establish PDCA mode of lean production management and make continuous improvement?

First, the PDCA cycle mode of site management

Whether the lean on-site management strategy can be effectively implemented needs good maintenance and continuous improvement. Maintenance is to work according to the standards set in the improvement activities, and solve the problems in site management in time by using the abnormal rapid response process. Lean improvement activities are to break the status quo, constantly improve, constantly set goals, and constantly achieve goals. If the result is different from the target, we should review the problem and continue to improve. Therefore, both the improved maintenance activities and the simple improvement activities are inseparable from the rotating PDCA management cycle, which enables the company to continuously improve, and the production site management of the enterprise also follows the PDCA cycle that can be applied to any activity.

Plan p (plan); Set challenging improvement goals for new problems found in each improvement; In order to successfully complete the set goals and make the most effective use of people, materials, methods and equipment, it is necessary to make improvement plans.

Realize d (do); Gradually implement and supervise the improvement plan.

Check c (check); It is to summarize the effect of the implementation of the improvement plan, check according to the improvement results and the problems reflected by SQDC evaluation, and evaluate which improvement projects are done well and which need to be improved.

Process a (action); Affirm or deny the inspection results, standardize the good results, analyze the reasons for unsuccessful improvement, enter the next improvement plan, and start a new round of PDCA cycle.

Second, continuous improvement.

In order to cope with the ever-changing market situation, enterprises must be more agile, be able to change their business and operation strategies frequently, in order to obtain the maximum profit, and at the same time greatly shorten the change cycle and continuously improve. Continuous improvement, CI) originated in Japan. Through the continuous improvement of on-site management, improving product quality, reducing product production cost and enhancing enterprise competitiveness are the essence of lean production idea on-site management. The specific steps to implement continuous improvement are as follows:

1. Create an efficient office for continuous improvement.

The staff of the continuous improvement office can be experts in internal lean travel, responsible for promoting, coordinating and guiding lean work, and determining the activities and contents of continuous improvement in on-site management. Instead of being responsible for specific change work, they act as mentors. Creating such an objective, independent and efficient office can promote continuous improvement more quickly. At present, the company-level continuous improvement office (including lean promotion office) has been established, and the continuous improvement offices of subordinate manufacturing centers and branches are under preparation.

2. Field investigation and quantitative analysis

On the basis of the above preparation, the on-site production management process was investigated to find out the problems existing in the on-site management process. At the same time, the quality, productivity, work in process, occupied area, turnaround time, material consumption, parts variety and so on in site management are measured and the specific values are calculated. At the same time, the existing problems are deeply analyzed to find out the specific reasons for the problems.

3, continuous improvement plan for the problem.

Analyze the problems found in the above-mentioned on-site management inspection in detail, find out the reasons, then put forward improvement suggestions for each selected project and determine several possible continuous improvement schemes. In this process, the participants in the company's on-site management are required to be responsible and do it themselves, and accelerate the implementation of continuous improvement (CI).
