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.
- 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.

|1||This methodology centers around giving confirmation that the quality mentioned will be accomplished.||This methodology focuses on fulfilling the quality requested.|
|2||Quality Assurance aims to prevent the defect||Quality Controls aim to identify and fix defects|
|3||It is a method to manage the quality- Verification||It is a method to verify the quality-Validation|
|4||It does not involve executing the program||It always involves executing a program
|5||It’s a Preventive technique||It’s a Corrective technique|
|6||It’s a Proactive measure||It’s a Reactive measure|
|7||It is the procedure to create the deliverables||It is the procedure to verify the deliverables.|
|8||Quality Assurance involves in the full software development life cycle||Quality Control involves in full software testing life cycle
|9||In order to meet customer requirements, Quality Assurance defines standards and methodologies||Quality Control confirms that the standards are followed while working on the product|
|10||Quality Assurance is performed before Quality Control||It is performed only after the Quality Assurance of the software is done|
|11||It is a Low-Level Activity; it can identify an error and mistakes that Quality Control cannot detect.||It is a High-Level Activity; it can identify an error that Quality Assurance cannot detect.|
|12||Its main motive is to prevent defects in the system. It is a less time-consuming activity||Its main motive is to identify defects or bugs in the system. It is a more time-consuming activity.|
|13||Quality Assurance ensures that everything is executed in the right way, and that is why it falls under verification activity||Quality Control ensures that whatever we have done is as per the requirement, and that is why it falls under validation activity|
|14||It requires the involvement of the whole development team||It requires the involvement only of the Testing team
|15||The statistical technique applied to QA is known as Statistical Process Control (SPC)||The statistical technique applied to QC is known as Statistical Quality Control|
