Extended data:

When setting up QA posts in the process of establishing organizational structure, it is necessary to equip the posts with sufficient resources, especially to allocate post personnel. Generally speaking, QA personnel can be divided into two categories according to the characteristics of enterprises: full-time and part-time

Full-time is to set up special QA personnel, whose main responsibility is quality assurance. When setting up this kind of personnel, the most important thing is to consider whether his knowledge, skills and quality meet the requirements of the organization and post. These requirements are based on differences in corporate culture and maturity.

For example, for an enterprise with weak sense of cooperation and strong bureaucracy, communication may be an important quality requirement of QA; For enterprises with low maturity and no institutionalized standard process, understanding the business and mastering QA professional knowledge may be the most important criteria for choosing QA.

Part-time job is to assign engineers to other functional departments or projects to participate in QA work, and each engineer acts as a potential QA. This is also an option for QA staffing, which is generally suitable for an open and quality-oriented culture.

In turn, it can greatly promote the construction of quality culture. However, this scheme should be carefully combined with organizational systems, such as reward and punishment system and cost system, otherwise it will easily lead to conflicts of interest.

Because the concept of QA was introduced into China soon, QA talents are quite scarce. In order to get enough resources to complete QA work, job rotation can also be adopted.

For example, project managers are allowed to rotate between project management positions and QA positions, and certain QA work experience is a necessary condition for project managers to take up their posts.

On the one hand, it solves the shortage of QA resources, on the other hand, it also promotes the rotation personnel to integrate QA ideas and methods into development and project management, and improve product quality to a greater extent.
