What is Quality Assurance (QA)?
Quality Assurance ordinarily known as QA Testing is defined as an exercise to certify that an organization is providing the best feasible product or service to clients.
What is Quality Control (QC)?
Quality Control in Software Testing is a systematic set of processes used to certify the quality of software products or services. The main ambition of the quality control process is to certify that the software product suits the actual requirements by testing and reviewing its functional and non-functional requirements. Quality control is mainly abbreviated as QC.
This article describes the difference between Quality Assurance and Quality Control.
Key Differences
- Quality Assurance is meant to stay away from deformity, though Quality control is expected to distinguish and fix the imperfections.
- Quality Assurance gives affirmation that the quality mentioned will be accomplished, while Quality Control is a methodology that spotlights satisfying the quality mentioned.
- Quality Assurance is finished in the product improvement life cycle, while Quality Control is finished in the product testing life cycle.
- Quality Assurance is a proactive measure, though Quality Control is a Responsive measure.
- Quality Assurance requires the contribution of all colleagues, while Quality Control needs just a testing group.
- Quality Assurance is done before Quality Control.
