People often get confused between Quality assurance (QA) and Quality Control (QC). They may sometimes use these two terms interchangeably. This is because the terms are inter-related features of Quality Management.

Quality Management is a broader field that ensures the quality of the software product is up to the needed quality level. You can design a standard quality management approach for the company you are working with. It is divided into four main sub-processes:

  • Quality Assurance
  • Quality Planning
  • Quality Control
  • Quality Improvement

Moving forward with that, there are many differences between QA and QC. In this blog, we will share those differences with you. But before moving to the differences, let us give you a brief introduction to software testing, QA, and QC.

Software Testing

Software testing is the process used to check if the developed software product matches the expected needs. It ensures that the developed software product is free from defects. It runs a system or software components using automated or manual tools. We can use these tools to assess one or more characteristics of interest. Companies use software testing to find bugs, gaps, or missing needs when compared to actual needs.

How Do We Define Quality

Quality means meeting the needs and expectations of a customer. It ensures that the product is free from lacks, defects, and consequential variants. People need to follow some predefined standards to satisfy customer needs.

Quality Assurance

Quality assurance is about monitoring the stages of a software development process. It is used to make sure that the company’s software is designed up to the needed standards. A quality assurance analyst ensures that the developers are meeting their deadlines. Also, if they inform other developers of the problem arising in their code.

QA vs QC

Quality Control

QC is a software engineering process. It ensures that the processes, techniques, approaches, and methods designed for the project are well followed. QC operates and verifies that the application meets the quality standards as defined. Quality control focuses on the quality examination of the end product. Its major function is to confirm the outcome regardless of the process used in production.

Quality Assurance Vs. Quality Control In Software Testing – What Is The Difference?

As a part of the quality management process, QA and QC perform different functions. Here we have listed some of the apparent differences between quality assurance and quality control. Let us have a look at this comparison to clarify your confusion.

Quality Assurance Quality Control
QA uses a static technique of testing. QC uses a dynamic technique of testing.
It verifies the product. Ensures that the developed product is as per the need of the company. It validates the product. Ensures the developed product meets all the expectations of the user.
QA focuses on avoiding defects. QC focuses on pointing and fixing defects.
QA is a preventative technique. QC is a corrective technique.
QA is a procedure-based methodology. QC is a product-based methodology.
We perform QA before QC. We perform QC after QA.
We use QA to manage the quality. We use QC to verify the quality.
Responsibilities of a QA include Software Development Life Cycle (SDLC). Responsibilities of a QC include Software Testing Life Cycle (STLC).
The whole team is responsible for QA. Only the tester is responsible for QC.
In the execution of a test, QA does not involve. QC involves in the execution of a test.
In QA, we identify the weakness in the early stages of the process. In QC, we identify the weakness after the product launch, or you can say, in the production environment.
In software development, we use QA to improve a product under development. QC is a set of strategies used to confirm the quality of the delivered product.
QA is an extensive action. QC is a product-related procedure.
QA set up a great quality administration framework.  QC makes sure that the client’s prerequisites are always met.
QA is process-focused. QC is product-focused.
QA implements procedures to prevent defects from arising. QC implements procedures to find more defects in a running system. It also fixes them.
QA involves human auditing of records or findings. It may include test plans or quality plans. QC involves the use of techniques for scripting or operating the software. A quick timeframe determines later if the system is working well.
Statistical Process Control (SPC) is the statistical technique used in QA. Statistical Quality Control (SQC) is the statistical technique used in QC.
QA is a low-level activity. QC is a high-level activity.
QA consumes less time. QC consumes more time.
Concerning software, QA becomes Software Quality Assurance (SQA). Concerning software, QC becomes Software Testing.
Example of QA activities: 

  • Process checklists
  • Process standards
  • Process documentation
  • Project Audit
Examples of QC activities:

  • Inspection
  • Deliverable peer reviews
  • The software testing process
