Quality Control
A reactive process that aims to detect defects, errors or problems and either reject a product or prevent a service from falling any further below desired standards and correcting whatever is needed to return the product or service to the desired standard. The process will occur at various stages of production or service delivery to verify compliance, or not. Once an issue had been identified, then as part of a quality management system, steps would be rapidly taken to improve the situation. The focus of quality control is on the physical product or how the service is delivered, as it arises.
Quality control activities can include the regular and routine sampling of products or service events, and the monitoring of deficiencies, deviations or defects from a standard. This will ideally help to address and eliminate these problems during the production stage or before they impact on service delivery and expectations of customers when they are using a product.
