What are the positions of QE, IPQC, OQC, IQC, AE and QC? There are many jobs, but I don't know what it means.

Qa is the abbreviation of English qualityassurance, and Chinese means quality assurance. Qc is the abbreviation of English qualitycontrol, which means quality control in Chinese. IPqc is a process inspection engineer, JQE is a quality engineer, Dqa is a design quality assurance engineer and SQE is a supplier management engineer. According to iso9000:2000, QA is defined as "a part of quality management, dedicated to providing trust that quality requirements will be met" and QC is defined as "a part of quality management, dedicated to meeting quality requirements". The definition in the standard is concise and difficult to be lengthy, which may make it difficult to understand clearly. In short, qc is directly committed to meeting the quality requirements of people and things; Qa is committed to convincing managers, customers and other interested parties that they have the ability to meet the quality requirements of people and processes. In some standards of software/informatization, the definition of qa includes: "Quality assurance refers to a series of planned and necessary work to make software products meet the specified requirements." (gb/t 12504- 1990 Computer Software Quality Assurance Plan Specification); "The plan and system model of all actions that must be taken to make a project or product meet the established technical requirements." (GB/T11457—1995 software engineering terminology). There is no direct definition of qc in these two standards. The definition of the same term is often different from different angles according to different purposes. For example, gb/t 12504- 1990 and GB/T1457-1995 have different definitions of qa according to GB/T 65438+. 2. Comparison of Emphasis between qa and qc In a software organization or project team, there are two roles, QA and qc. The main points of these two roles are as follows: other main differences between qa and qc include: QA with necessary qualifications is a senior talent in the organization, which needs to fully grasp the process definition of the organization and be familiar with the engineering technology used in the project; Qc includes not only senior talents such as software test designers, but also middle and junior talents such as general testers. Some foreign software companies require qa to have more than two years of software development experience and more than half a year of experience as an analyst and designer. You should be trained not only in qa, but also in performing the duties of project manager. In the project team, qa is independent of the project manager, and the project manager does not conduct performance appraisal; Qc is led by the project manager. During the project operation cycle, the performance of qc is usually decided by the project manager. Qa activities run through the whole process of project operation; Qc activities are generally set in a specific stage of project operation, and may be completed by different roles at different control points. For a competent qa, tracking and reporting the findings in project operation is only the basic part of his job responsibilities. More valuable work includes providing process support for the project team, such as providing case studies and reference data of similar projects in the past for the project manager, and introducing and explaining applicable process definition documents for project team members. The main activity of qc is to find and report the defects of products.
