SQA vs SQC

“SQA” and “SQC” stand for “Software Quality Assurance” and “Software Quality Control” respectively. They are two different functions of software quality. One assures the quality as the name suggests, and the other checks that all processes and procedures are being carried out properly. The terms seem very similar, but there are some basic differences between them.

SQA (Software Quality Assurance)
Software Quality Assurance is a software quality function which helps in assuring that all the processes, standards, and procedures taking place in a project are appropriate and are being implemented correctly. SQA includes monitoring the methods and processes used for a software program to ensure its quality. It includes the software development process as a whole including processes like software design, source code control, coding source, change management , code reviews, release management, configuration management, etc. There are many different methods by which the SQA is accomplished, and there are many different standards to which the quality should conform to like ISO 9000 or CMM,I etc. Software Quality Assurance is divided into goals, abilities, activities, commitments, measurements, and finally verifications.

SQC (Software Quality Control)
Software Quality Control is a software quality function which helps in checking that a project follows some particular procedures and processes, and the project produces the external and internal products which are required of them. In general terms, control and quality testing can be treated as the same. SQC is used by different organizations to ensure the software product meets the demands of the customer and also confirms that the organization has the ability to produce improved products in the future.

Software Quality Control is useful in supporting functional requirements, non-functional requirements, and also checking the performance, supportability, and usability of the project. It also makes sure that the software keeps working in conditions which were unforeseen and the defect rate is kept relatively low. All the processes and procedures are validated and verified by software quality control. Testing of a project is identified with Software Quality Control only. The testing is associated with functional requirements only.
