1. QC and QA
QC: Quality Control, the general term for quality control, product quality inspection, analysis, improvement and non-conforming product control related personnel after quality problems are found.
IQC (Incoming Quality Control) means quality control of incoming materials, referred to as incoming material control.
IPQC (In Put Process Quality Control) in Chinese means process control, which refers to the quality control of the final packaging process of products from materials to production.
FQC (Finish or Final Quality Control) finished product quality inspection
OQC (Out Quality control) finished product delivery inspection
DQC (Design Quality Control) design quality control
MQC (Manufacture Quality Control) process quality inspection
QA: Quality Assurance, quality assurance, through the establishment and maintenance of a quality management system to ensure that there is no problem with product quality.
IDQA (Design Quality Assurance) design quality assurance, such as DQA manager (design quality certification manager)
QE (Quality Engineer) quality engineer
JQE (Joint Quality Engineer) client quality engineer, that is, the quality engineer hired by the supplier to work for the customer, is the eyes and ears of the customer's SQE.
SQE (Supplier Quality Engineer) supplier quality engineer.
Second, the difference between QA and QC
QA not only needs to know where the problems are, but also how to formulate solutions to these problems and how to prevent them in the future; QC needs to know that if there is a problem, it should be controlled, but it does not necessarily need to know why it should be controlled in this way.

[An inappropriate analogy] QC is the police and QA is the judge. QC only needs to catch those who violate the law. It cannot prevent others from committing crimes and convict others. The judge is to make laws to prevent crimes and follow the law. Declare the result of the disposal.
QC mainly focuses on quality inspection activities after the fact. By default, errors are allowed, and errors are expected to be discovered and selected. QA is mainly an advance quality assurance activity, focusing on prevention, hoping to reduce the probability of errors.
QC is the operation technology and activities taken to make the product meet the quality requirements. It includes inspection, correction and feedback. For example, after QC conducts inspection and finds defective products, they will be eliminated, and then the bad information will be fed back to the relevant departments to take improvement measures. Therefore, the scope of QC's control is mainly within the factory. Its purpose is to prevent the input, transfer, and delivery of unqualified products, to ensure that products meet quality requirements and only qualified products can be delivered to customers.
QA is to provide trust to meet customer requirements, even if the customer is convinced that the product you provide can meet his requirements, it is necessary to review customer requirements from the beginning of market research and later, product development, order and material procurement, incoming inspection, and production process Evidence is left at each stage of control, shipment, after-sales service, etc., confirming that every step of the factory's activities is carried out in accordance with customer requirements.
The purpose of QA is not to ensure product quality, it is the task of QC to ensure product quality.
QA is mainly to provide assurance. Therefore, it is necessary to manage the entire process from understanding customer requirements to after-sales service. This requires companies to establish a quality control system, formulate corresponding documents to regulate the activities of each process and leave evidence of the implementation of the activities in order to provide trust.
This kind of trust can be divided into two types: internal and external: the external, even if the customer is at ease, believe that the factory produces and deliver products according to its requirements; the internal is to let the factory owner rest assured, because the boss is the first person responsible for product quality, and the product has quality accidents. He has to take full responsibility. This is also the main requirement for countries to formulate product quality laws to encourage companies to really pay attention to quality. Therefore, in order to avoid responsibility for quality, the boss must standardize various activities with documents and leave evidence. However, it is impossible for the boss to know whether the internal personnel of the factory operate according to the document requirements. This requires QA to conduct audits on his behalf to understand whether the document requirements are complied with, so that the boss can believe that the various activities of the factory are carried out in accordance with the document. Reassured him.
