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".

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.
