 Quality control, or QC for short, is a process by which entities review the quality of all factors involved in production. ISO 9000 defines quality control as a part of quality management focused on fulfilling quality requirements. This approach places an emphasis on three aspects enshrined in standards such as ISO 9001, 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. Inspection is a major component of quality control, where physical product is examined visually or the end results of a service are analyzed. Product inspectors will be provided with lists and descriptions of unacceptable product defects such as cracks or surface blemishes for example. Quality of the outputs is at risk if any of these three aspects is deficient in any way.
