Quality Control
Difference between Quality Assurance and Quality Control.
Historically, Quality Control came first. Larger companies have had Quality Control Departments since the early 1900's. Perhaps the Egyptian used some form of Quality Control to get all the stone on the Pyramids to fit together so well.
Quality Control is the physical process for controlling quality in manufacturing products. It has no influence in the design of the product or how it is made. The process is structured in a similar way to Quality Assurance with stages from planning through to Evaluation.
As companies realised that to produce high quality products and services, they had to look at the quality standards of the whole company not just production. Quality Control evolved into Quality Assurance and has now become a small but important part of the companies overall Quality Management System.
From American Society of Quality.Quality Control Department
The QC Department is organised to inspect the quality of the product or service. Their role is to measure, record and maintain standards of production.
Quality cannot be inspected into the product, it has to be made correctly from the start.
