Quality controlFrom Wikipedia, the free encyclopedia

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

places an emphasis on three aspects:[citation needed]

1. Elements such as controls, job management, defined and well

managed processes,[1][2] performance and integrity criteria,

and identification of records

2. Competence, such as knowledge, skills, experience, andqualifications

3. Soft elements, such as personnel, integrity, confidence,organizational culture, motivation, team spirit, and quality

relationships.

Controls include product inspection, where every product is examinedvisually, and often using a stereo microscope for fine detail before theproduct is sold into the external market. Inspectors will be providedwith lists and descriptions of unacceptable product defects such ascracks or surface blemishes for example.

The quality of the outputs is at risk if any of these three aspects isdeficient in any way.

Quality control emphasizes testing of products to uncover defects andreporting to management who make the decision to allow or denyproduct release, whereas quality assurance attempts to improve andstabilize production (and associated processes) to avoid, or at leastminimize, issues which led to the defect(s) in the first

place.[citation needed] For contract work, particularly work awardedby government agencies, quality control issues are among the top

reasons for not renewing a contract.[3]

"Total quality control", also called total quality management, is an approach that extends beyond ordinarystatistical quality control techniques and quality improvement methods. It implies a complete overview and re-evaluation of the specification of a product, rather than just considering a more limited set of changeable featureswithin an existing product. If the original specification does not reflect the correct quality requirements, qualitycannot be inspected or manufactured into the product. For instance, the design of a pressure vessel shouldinclude not only the material and dimensions, but also operating, environmental, safety, reliability andmaintainability requirements, and documentation of findings about these requirements. Total QualityManagement (TQM) refers to management methods used to enhance quality and productivity in businessorganizations. TQM is a comprehensive management approach that works horizontally across an organization,involving all departments and employees and extending backward and forward to include both suppliers andclients/customers. TQM is only one of many acronyms used to label management systems that focus on quality.Other acronyms include CQI (continuous quality improvement), SQC (statistical quality control), QFD (qualityfunction deployment), QIDW (quality in daily work), TQC (total quality control), etc. Like many of these othersystems, TQM provides a framework for implementing effective quality and productivity initiatives that can

increase the profitability and competitiveness of organizations.[4]

Quality control in project management

In project management, quality control requires the project manager and the project team to inspect the

accomplished work to ensure its alignment with the project scope.[5] In practice, projects typically have a

dedicated quality control team which focuses on this area.[citation needed]
