QA vs QC Testing

If you are new to the field of software development or already familiar with its dynamic nature you are more likely familiar with the terms Quality Assurance (QA) and Quality Control (QC). While the interchangeable use of QA vs QC is a common misunderstanding among many where they fail to understand the difference between QA and QC. These similar technical terms have completely different but equally significant roles in the development process. Lets break down these two terms and understand the significance they play.

Quality Assurance (QA) and Quality Control (QC)

What is Quality Assurance (QA)?

Quality Assurance (QA) testing is essential when it comes to software testing and qa. It refers to the systematic procedures that must be implemented to ensure that the software product is according to a desired standard before its release. In essence QA testing is the backbone of a strong software development cycle making certain that quality standards are followed at every stage from design to implementation.

What is Quality Control (QC)?

Testing for quality control (QC) is a crucial step in the software development process and is a reactive process that reviews actual results to make sure they fulfill the intended design and standards. QA uses planning and process optimization to prevent faults whereas QC finds and fixes flaws in the final product ensuring that the end result is both functional and fulfils the highest standards of quality.

QA vs QC: Comparison Overview

Quality Assurance (QA) and Quality Control (QC) play individual unique roles in ensuring your product is reliable and maintains perfection by coordinating and working together to plan and perfect every detail. Imagine software development as building a house, you may think of quality assurance (QA) as the architect who designs the blueprint ensuring the plan meets all regulations and standards before construction begins. In contrast quality control (QC) is equivalent to the building inspector who examines the house at various stages of construction and after completion to ensure everything has been built according to the plan and standards.

Thus, the difference between QA and QC lies in their focus. QA is process oriented aiming to improve and the production processes, while QC is product oriented concerned with identifying defects in the final output. Understanding the QA/QC meaning helps in acknowledging their distinct yet complementary roles in ensuring the quality of your software.

Knowing the difference between QA and QC testing is essential when you are creating top quality software. These two parts of software testing and QA play different but complementary roles which are highlighted as follows:

Nature: 1. QA is a preventative technique 2. QC is a corrective technique

Standards and Procedures 1. QA defines standards and procedures that need to be followed in order to meet customer requirements 2. QC ensures standards are followed while working on the product

Ultimate Objective: 1. QA aims to prevent defects and is a process-oriented procedure 2. QC aims to identity and correct defects and is a product-oriented procedure

Quality Management 1. QA makes sure the quality team is doing the right things in the right way. 2. QC makes sure that whatever the quality team has done is as per the requirement.

Tools 1. QA is a managerial tool and used for verification 2. QC is a corrective tool and used for validation.

How Do QA QC Testing Work Together?

In software development, QA, QC, and Testing operate hand-in-hand to uphold quality standards. QA sets the standard and processes to maintain quality from start to finish, while QC verifies compliance by scrutinizing the final product against these standards. Software Testing and QA then puts the product through rigorous examination to ensure functionality and performance align with expectations. This joint approach encompassing QA and QC ensures that any discrepancies are caught early on ensuring continuous improvement. By understanding the difference between QA and QC teams can streamline their efforts, resulting in an efficient development process and a up to mark final product that meets the demands of software testing and QA.


To sum up, the interaction of quality assurance, quality control, and testing is essential to achieving software excellence. A high-quality product is the result of QA setting the standards, QC  guaranteeing compliance, and Testing validating performance. It is essential for teams to comprehend the difference between QA and QC in order to optimize their software testing and QA efforts. Teams can quickly identify and fix problems by combining these components properly which guarantees that the end result will satisfy the standards set forth. In addition to encouraging a system of quality, the collaborative approach gives teams the ability to consistently produce excellent software solutions.
