Quality control is the term used to describe the process of ensuring that a new product or service meets all the standards that its intended audience would expect. It usually follows this as a framework for deciding on a standard and defining what passing standards mean.
The quality control phase of a physical product is slightly different from the quality control phase of a digital product, such as a website or online service. With physical items, you would usually take a representative sample of the product produced and test them against your quality control standards and test them to determine the percentage failure rate.
