Product quality has advantages and disadvantages. People often regard high-quality products as "good quality", and inferior quality products as "bad quality". In fact, there is no "good" quality, only the quality that meets the requirements. Good products are made, not tested. Therefore, the key to quality lies in management.

 

01 the quality is decided by the customer

No matter how luxurious the equipment is, how excellent the performance is and how beautiful the appearance is, the products are not what the customers need. As a result, they will be eliminated. Therefore, the manufacturer's position and concept: to replace "best quality" with "optimal quality"; and "optimal quality" is to make customers feel "the most satisfied quality".

 

1. Meet the current needs of customers

Meet specific specifications

Good function

Easy to use

Beautiful appearance

 

2. Guarantee the future needs of customers

Durable, not easy to break down

Safe and reliable

The external environment has little influence

Considerate for customers

 

02 Quality does not increase costs, but reduces costs

People have a wrong idea about quality: to improve quality is to raise cost.

For the manufacturing industry, if the defect rate decreases, the cost will decrease

There is no need to spend the cost of inspection and correction of defective products;

No defective products, save the cost of material replacement and machine adjustment;

More production opportunities due to the reduction of defective products;

The continuous production capacity of production can be improved when the defect rate is reduced.

 

03 quality management

Quality management is to reduce the instability of product quality to the minimum, or even eliminate. Quality management is all the activities that managers carry out in order to achieve the goal of the Department.

1. Starting from unstable product quality

The unstable factors come from:

personnel

equipment

Material Science

method

Environmental Science

 

2. Foundation of quality management

1) Standardization

Standardization is an indispensable criterion for the management of unstable quality, and the "killer" of savage manufacturing.

Unification

Generalization

serialization

Simplification

 

2) Informatization

Data can be said to be the most effective way to manage the instability of dual hair. The so-called data, is to try to express things in numerical value.

 

3) Quality education

ontinuous improvement of staff quality awareness is the eternal theme of enterprises, so that employees do the right thing for the first time.

 

4) Quality cost analysis

Prevention cost

Appraisal cost

Failure cost

 

5) Quality defect analysis

Minor defects

General defects

serious disadvantage

Fatal defects

 

6) Equipment management

Equipment optimization

Equipment maintenance

 

3. "Three require" and "three inspections"

1) "Three require"

Require the staff to operate according to the process, drawings and standards (pre job training and on-site guidance);

The inspector is required to inspect according to the process, drawing and standard;

The technical department is required to prepare process, draw drawings and formulate standards.

2) "Three inspections"

Employee self inspection

Patrol inspection

Mutual inspection among employees
