Quality Control vs Quality Assurance: Differences, Cooperation, and Risks
Quality assurance (QA) and quality control (QC) are two terms that are often used interchangeably. Although similar, there are distinct differences between the two concepts.
Quality Assurance is popularly known as QA Testing, is defined as an activity to ensure that an organization is providing the best possible product or service to customers.
Quality Сontrol popularly abbreviated as QC. It is a Software Engineering process used to ensure quality in a product or a service. It does not deal with the processes used to create a product; rather it examines the quality of the “end products” and the final outcome.
The main difference between QA and QC:
- While doing ‘QA’, we define the processes, policies, and strategies, establish standards, develop checklists that need to be used, and followed throughout the life cycle of a project.
- While doing QC we follow all those defined processes, standards, and policies that we laid down in QA to make sure that the project is maintaining high quality and the final outcome of the project at least meets the customer’s expectations.
