Quality control ensures products or services meet specific requirements. A team tests products or observes services to identify issues. Quality assurance examines the process to prevent problems. Companies use quality control to evaluate employees and ensure customer satisfaction.
Quality control is a process used to ensure a certain level of quality in a product or service. It could include any action that a company deems necessary to provide control and verification of certain characteristics of a product or service. Very often, it is a question of thoroughly examining and testing the quality of the products or the results of the services. The fundamental objective of this process is to ensure that the products or services provided meet specific requirements and characteristics, such as being reliable, satisfactory, secure and taxable.
Quality control companies typically have a team of workers who focus on testing a number of products or observing services in progress. The products or services that are reviewed are usually chosen at random. The goal of the quality control team is to identify products or services that do not meet the quality standards specified by the company. If a problem is identified, the work of a QA team or professional could result in the interruption of production or service until the problem has been corrected. Depending on the particular service or product, as well as the type of problem identified, production or services may not cease entirely.
Usually, it is not the job of the QC team or professional to correct quality problems. Typically, other people are involved in the process of finding the cause of quality problems and fixing them. After the problems have been overcome and adequate quality has been achieved, the product or service continues production or implementation as usual.
Many types of companies perform these types of quality checks. Food manufacturers, for example, often have employees who test finished products for taste and other qualities. Garment manufacturers have workers inspect garments to make sure they are sewn correctly. Service-oriented companies often have representatives who observe the services performed or who do follow-up checks to ensure everything was performed correctly.
Quality control might also involve evaluating people. If a company has employees who lack the proper skills or training, have difficulty understanding directions, or are poorly informed, the quality of the company’s products or services may be degraded. This is especially important for service-oriented businesses, because employees are the product they deliver to customers.
Quality control is often confused with quality assurance. Though the two are similar but there are some basic differences. Quality control is about examining the product or service – the end result – and quality assurance is about examining the process that leads to the end result. A business would use quality assurance to ensure that a product is manufactured the right way, reducing or eliminating potential problems with the quality of the final product.
