Quality control, or QC for short, is a process by which entities review the quality of all factors involved in production.

ISO 9000 definition

ISO 9000 defines quality control as "A part of quality management focused on fulfilling quality requirements".

Aspects of quality control

• Elements such as:
  • Controls
  • Job management
  • Defined and well managed processes
  • Performance and integrity criteria
  • Identification of records
• Competence, such as:
  • Knowledge
  • Skills
  • Experience
  • Qualifications
• Soft elements, such as:
  • Personnel
  • Integrity
  • Confidence
  • Organizational culture
  • Motivation
  • Team spirit
  • Quality relationships

Controls

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 assurance

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 (and associated processes) to avoid, or at least minimize, issues which led to the defect(s) in the first place.
