Origin of quality control:
maintenance of standards of quality of manufactured goods
A control, such as inspection or testing, introduced into an industrial or business process to ensure quality.
Quality control, or QC for short, is a process by which entities review the quality of all factors involved in production. This approach places an emphasis on three aspects: ⁕Elements such as controls, job management, defined and well managed processes, performance and integrity criteria, and identification of records ⁕Competence, such as knowledge, skills, experience, and qualifications ⁕Soft elements, such as personnel, integrity, confidence, organizational culture, motivation, team spirit, and quality relationships. Controls include product inspection, where every product is examined visually, and often using a stereo microscope for fine detail before the product is sold into the external market. Inspectors will be provided with lists and descriptions of unacceptable product defects such as cracks or surface blemishes for example. The quality of the outputs is at risk if any of these three aspects is deficient in any way. Quality control emphasizes testing of products to uncover defects and reporting to management who make the decision to allow or deny product release, whereas quality assurance attempts to improve and stabilize production to avoid, or at least minimize, issues which led to the defect in the first place. For contract work, particularly work awarded by government agencies, quality control issues are among the top reasons for not renewing a contract.
