What is quality control and steps of quality control?

It is not enough for enterprises to rely on directional strategic choice to survive and develop in the fierce market competition. Any competition among enterprises is inseparable from the competition of "product quality". Without excellent product quality, enterprises will eventually disappear in the wave of market economy. Product quality, as the most difficult to control and the most prone problem, often makes suppliers miserable. Small ones return goods and lose money, large ones lose customers and close their doors. Therefore, how to effectively carry out process control is the core of ensuring product quality and improving product quality, promoting enterprise development, winning the market and making profits. This paper will briefly introduce quality control, including the concept and steps of quality control.

Concept of quality control

The operation technology and activities adopted to meet the quality requirements are called quality control. That is to say, quality control is to monitor the quality formation process and eliminate the factors causing nonconformity or unsatisfactory effect in all stages of the quality ring, so as to meet the quality requirements and obtain economic benefits. Quality control refers to the activities of technical measures and management measures taken to make the products or services meet the quality requirements. The objective of quality control is to ensure that the product or service quality can meet the requirements (including explicit, customary, implicit or mandatory provisions).

Steps of quality control

quality control can be roughly divided into seven steps:

(1) Select the control object;

(2) Select the quality characteristic value to be monitored;

(3) Determine specifications and standards and specify quality characteristics;

(4) Select the monitoring instrument that can accurately measure the characteristic value or corresponding process parameters, or self-made test means;

(5) Conduct actual tests and make data records;

(6) Analyze the reasons for the differences between actual and specifications;

(7) Take corresponding corrective measures. After taking corresponding corrective measures, the process shall still be monitored to keep the process at a new control level. Once new impact factors appear, it is also necessary to measure the data and analyze the causes for correction. Therefore, these seven steps form a closed process called "feedback loop". This has something in common with DMAIC of 6Sigma quality breakthrough mode.

There are two key points in the above seven steps:

(1) Design of quality control system;

(2) Selection of quality control technology.
