QA uses a static testing technique and it falls under verification which means to make sure that product is being developed as per the requirements.

QC is the process where weaknesses are identified after product is delivered in other words in the production environment. It is necessary to undertake QA planning at the beginning of a project to outline software specifications. The outcomes of QA include dev process inspection, test plans, and tracking tools setup. Quality Control, on the contrary, implements activities aimed at determining the level of quality of the product.

While performing QC, you should be following all the standards and policies set up by the QA. QC assumes usage of the different types of testing unit, integration, vulnerability testing, etc , reliance on testing metrics , and reports.

The techniques of quality measurement should be agreed upon before the project starts since some of the tests and testing metrics are applied to improve the efficiency of the entire SDLC process and not the final product.

Quality Assurance serves as a preventive technique and a proactive measure to ensure the quality of the product. Quality Control, conversely, is a corrective technique and a reactive measure.

One of the key differences between QA and QC lies in the division of responsibilities. QA is often a shared responsibility between all development team members. QC, instead, is mostly executed by a testing team whose primary role is to test the completed software to identify defects.

QC is an essential part of any product development as it helps fine-tune the final deliverable. As previously mentioned, QA is process-oriented, focusing on preventing quality issues. It entails processes such as:. QC is focused on the final product. To ensure quality, QC encompasses specific procedures, among which are:.

The Quality Assurance team is responsible for defining the processes, establishing standards, developing checklists, etc. Quality Control is, in turn, the process to verify that deliverables comply with the functional requirements. This is usually done during the testing phase. Software Quality Assurance , QA , is a planned and systematic way of creating an environment to assure that the software product being developed meets the quality requirements.

QA refers to the implementation of well-defined standard practices and methods. It is a pro-active quality process. This process is controlled and determined at managerial level. Quality assurance focuses on the process checklists, process standards, project audits, methodology and procedures for development. It is a preventive process that aims at establishing the correct methodology and standards to provide a quality conducive environment to the product being developed.

In this sub process, quality assurance plan is created for a particular project. In the quality assurance plan, organizational standards are selected which are applicable to a project. It should also involve the plan for quality control.

Quality assurance planning details out what QC activities are performed, when the QC activities are performed and who will perform those. It also contains details of resource required, tools and techniques to be used for performing quality control.

Quality Control, QC, is the set of activities that control the quality of product being developed by identifying any bugs that might be present. Quality control process is a subset that falls under the quality assurance. It is a corrective process. The task of actual testing is performed to find out and identify the bugs present in the product. The bugs are raised to the developers, who then try to fix them.

After fixes, the product is verified again such that the functionalities and features are working as required. QC process assures that that the product being developed is of the required quality.

Examples of quality control activities include inspection, deliverable peer reviews and the software testing process. Quality improvement is a formal approach to analyse the feedback received from the quality control team. In this process efforts are put systematically to identify any room of improvements in the existing standards and procedures.

The target is to improve the process that establish the standards of quality in the organization. Quality control activities are performed after the software has been developed. We have listed down the differences between quality assurance and quality control to further clarify your concept:.

You may like to read more about the quality assurance vs quality control. You are probably wondering what is the difference between tools and techniques, when we talk about quality assurance vs quality control. Well, we have listed down the tools and techniques for QA and QC separately so that you can understand and distinguish between them easily. The characteristic feature of software quality assurance is defining the organizational processes and standards.

The process shall serve as a guideline and improve over time. It is critical that the organizational standards are defined by experts as it will lay the foundation of quality assurance and assures development of reliable, quality products. The standard is harmonized with the software life cycle process and contains requirements for initiating, planning, controlling and executing the Software Quality Assurance. Quality audit is a quality assurance technique that examines the work products and evaluate whether the software product has followed the standards, guidelines, regulations, plans and procedures.

It a systematic approach to examine all the required procedures and standards were considered at the time of product development and testing. The following tools are indispensable while you are setting up the quality assurance process for your organization:.

Cost benefit analysis is a systematic approach of evaluating an investment against its expected benefits. Most people get confused when it comes to pin down the differences among Quality Assurance, Quality Control, and Testing.

Although they are interrelated and to some extent, they can be considered as same activities, but there exist distinguishing points that set them apart. Generally, it is an independent examination of processes involved during the testing of a software.

As per IEEE, it is a review of documented processes that organizations implement and follow. As per IEEE94, inspection is a formal evaluation technique in which software requirements, designs, or codes are examined in detail by a person or a group other than the author to detect faults, violations of development standards, and other problems.
