Identify eight wastes in the lean production process

Leading Word: In the development process of a production company, in order to enhance its own competitiveness, companies should reduce any unnecessary waste in the production process as much as possible, save costs, improve work efficiency, and promote lean development. To realize the lean production of a company, first of all you must learn to identify the “eight wastes” in lean production.

What is lean production?
"Precision" means producing the necessary quantity of urgently needed products in the market at an appropriate time;
"Benefit" refers to the effectiveness of all business activities.

Waste of lean production processes 1. Activities that do not add value.
2. Although it is a value-adding activity, the resources used exceed the “absolute minimum” limit and it is also a waste.

Lean core <br> identify and eliminate waste <br> <br> lean manufacturing process of the eight wasted <br> waste in lean manufacturing process is divided into eight parts: waste inventory, waste handling, processing Waste, excessive waste of processing, waste of action, waste of management, waste of waiting, and waste of quality.

What are the benefits of eliminating waste?
Eliminating waste can benefit customers, companies and employees. Customers: Meet all product expectations.
Companies: reduce costs, improve quality; improve operational flexibility and reputation;
Employees: The work environment is safer and easier to operate; consistent work beats; enhanced sense of honor for work area and work quality.

Waste in the production process: 1. Waste of processing 2. Processing too much premature waste 3. Action waste

The waste of processing 1. The quality and size of the designed product must meet the needs of the customer. If the private design of the production operation results in the loss of human financial and material resources in the later period, the processing waste will be formed.
2. Some of the increased product performance during processing is not used during the entire life cycle. This is also a waste of processing.

Too much premature processing waste 1. Compare the actual situation of production with the material control plan and analyze the difference. If there is no need for a certain product, the processing is completed within the planned deadline, which is the premature waste of processing. To increase the number of product processing outside the planned quantity is to waste excessive processing.
2. Identify waste by comparing the requirements of materials for production schedules and warehouse item lists.

Waste of Action <br> Unnecessary actions, value-added actions, and slow actions in lean production can be called action waste.

There is waste in the production process 1, 2 waste handling, waste <br> <br> stock inventory of waste <br> correctly identify the inventory of waste is to proceed from the following three aspects:
Analyzing Value Streams Identifying safety stocks and cycle stocks allows the necessary waste to exist.

Analyze the value flow chart: Analyze the in-process products from parts and components, semi-finished products assembly, finished product assembly, and product packaging. Generally, there are waiting, missing materials, and shutdowns, which will result in the waste of some products in process. In addition, the minimum amount of excess inventory is also a waste of inventory.
Identifying safety stocks and cycle stocks: Generally, the maximum value of safety stock fluctuations for three consecutive cycles is compared with the company's specifications. Parts that exceed safety stock plus cycle stocks or less than periodic stocks are waste of materials.
Allowing the existence of necessary waste: Considering the seasonal characteristics of procurement, development strategies, etc., the existence of these wastes is necessary.

Waste Management 1. Compare the actual situation of production with the material control plan and analyze the differences. If there is no need for a certain product, it will be processed within the planned deadline, which means that the processing is prematurely wasted. To increase the number of product processing outside the planned quantity is to waste excessive processing.
Second, identify waste by comparing the requirements of materials for production schedules and warehouse item lists.

Waiting for waste <br> First, set the formula balance rate for the assessment, if the calculated working hours is lower than the standard value, indicating that there is waiting for waste in production;
2. Arrange for a special production line supervision or workshop work to instruct the trainer to conduct on-site inspections and find that the waste is waiting to be corrected on the spot;
Third, compare the operating instructions, especially analysis of man-machine operations, three-level tables, etc., to identify waiting waste.

The Waste of Quality <br> There are three ways to identify the waste of quality:
First, check the qualified rate of raw materials for finished products, finished products and other aspects;
Second, the analysis of CPK (company process capability) indicators;
Third, identify directly in the design.

The production of Xiamen Yingruifeng Electronics revolves around “lean manufacturing”. We correctly identified the “eight wastages” that existed in the lean production process and effectively and timely adopted effective measures to minimize any excess in the production process. Waste, save costs, increase work efficiency, and promote lean development.
