Quality inspector in a Volkseigener Betrieb sewing machine parts factory in Dresden, East Germany, 1977. Quality control (QC) 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". [1]
Advanced product quality planning (APQP) is a framework of procedures and techniques used to develop products in industry, particularly in the automotive industry.It differs from Six Sigma in that the goal of Six Sigma is to reduce variation but has similarities to Design for Six Sigma (DFSS).
Management of quality was the responsibility of the Quality department and was implemented by Inspection of product output to 'catch' defects. Application of statistical control came later as a result of World War production methods, which were advanced by the work done of W. Edwards Deming , a statistician , after whom the Deming Prize for ...
A product's durability for example, can seldom be observed directly; it usually must be inferred from various tangible and intangible aspects of the product. In such circumstances, images, advertising and brand names -inferences about quality rather than the reality itself- can be critical.
Product quality data is statistically charted to distinguish between common cause variation or special cause variation. [25] Walter Shewart of Bell Telephone Laboratories recognized that when a product is made, data can be taken from scrutinized areas of a sample lot of the part and statistical variances are then analyzed and charted.
Continued process verification (CPV) is the collection and analysis of end-to-end production components and processes data to ensure product outputs are within predetermined quality limits. In 2011 the Food and Drug Administration published a report [ 1 ] outlining best practices regarding business process validation in the pharmaceutical ...
The purpose of a technical peer review is to remove defects as early as possible in the development process. By removing defects at their origin (e.g., requirements and design documents, test plans and procedures, software code, etc.), technical peer reviews prevent defects from propagating through multiple phases and work products and reduce the overall amount of rework necessary on projects.
Quality engineering is the discipline of engineering concerned with the principles and practice of product and service quality assurance and control. [1] In software development, it is the management, development, operation and maintenance of IT systems and enterprise architectures with high quality standard.
