QA(QUALITY ASSURANCE) means "quality assurance" in Chinese, and it is defined in ISO 8402: 1994 as "all planned and systematic activities implemented in the quality management system, and verified as required to provide enough trust to show that the entity can meet the quality requirements".
Some organizations that implement ISO9000 will set up such departments or posts to be responsible for the quality assurance functions required by ISO9000 standards, and the personnel who hold such jobs are called QA personnel.
QC is the abbreviation of English quality control, and Chinese is "quality control". In ISO 9000: 20 15, quality management is defined as "guiding and controlling the quality coordination activities of the organization". Quality control is defined as "a part of quality management, committed to meeting quality requirements".
According to the control characteristics and sequence of products in the process, product quality control can be divided into four stages: incoming quality control (IQC), process quality control (IPQC), final inspection and verification (FQC) and ex-factory quality control (OQC).

Quality control classification:
FQC: that is, the final quality control, that is, to check the quality of products after all processes are completed.
IQC: The quality control of incoming materials is to confirm the quality of purchased materials or products, reduce the quality cost and realize effective control.
IPQC: that is, process quality control, which is to control the quality of products from production to packaging, also called inspection.
OQC: namely, delivery quality control, which comprehensively checks and confirms products to ensure that the goods received by customers are in conformity with the agreed contents.
Quality assurance summary:
QA activity is a difficult process in CMMI implementation. In view of the current implementation of quality assurance process in China, this paper expounds the position, principles, activities and implementation of quality assurance. At the same time, the relationship between quality assurance, quality control and testing, and the best practice of implementing quality assurance activities are discussed, which provides a basis for organizing and implementing process improvement.
Overview of quality assurance:
When using CMMI model to implement process improvement, it is necessary to establish the organizational functions and roles of QA and implement the activities of "process and product quality assurance". The purpose of these activities is to enable project personnel and managers at all levels to correctly understand the work products and processes in the whole project life cycle, thus supporting the delivery of high-quality products and services.
Because CMMI model is based on the western corporate culture background and contains the idea of decentralization, IT is very important for domestic IT and software enterprises to understand and establish QA mechanism and make better use of CMMI model to improve their processes.
However, at present, there are misunderstandings about the significance and understanding of QA in domestic IT and software enterprises, which leads to QA activities becoming a mere formality or not playing its real role in the implementation process improvement activities.
