quality assurance refers to activities associated with guaranteeing the quality of a product or service.
quality control is based on the scientific method, which includes the phases of analysis, relation, and generalization.
The inputs to the quality assurance process are:Output from quality planning - The following output items from the quality planning process become the input to the quality assurance process:• Quality management plan - This plan is the output of the quality planning process, and it describes how QA will be performed for this project.• Quality metrics - A quality metric is an operational criterion that defines in specific terms what something (such as a characteristic or a feature) is and how the quality control process measures it. The quality metrics developed during quality planning, such as defect density, failure rates, reliability, and test coverage, must be employed during QA.• Process improvement plan - The process improvement plan, helps improve the quality of the project and must be implemented during QA.

A job description provides the quality assurance professional with the list of tasks performed in a particular job and the performance steps (procedures) required to perform each of the tasks.
Quality ControlEmphasizes testing of products to uncover defects, and reporting to management who makes the decision to allow or deny the release.Quality AssuranceAttempts to improve and stabilize production, and associated processes, to avoid, or at least minimize, issues that led to the defects in the first place.
Quality control focuses on identifying defects in products or services, while quality assurance focuses on preventing defects from occurring in the first place. Quality control involves inspecting and testing products, while quality assurance involves implementing processes and procedures to ensure consistent quality.
different between quality control & quality assurance
Quality assurance focuses on preventing defects in the production process, while quality control involves identifying and fixing defects in the final product. Quality assurance is proactive, ensuring that processes are in place to meet quality standards, while quality control is reactive, inspecting and testing products to ensure they meet those standards.
Quality assurance in software testing focuses on preventing defects by establishing processes and standards, while quality control involves identifying and fixing defects in the software product. In essence, quality assurance is proactive, aiming to prevent issues from occurring, while quality control is reactive, addressing issues that have already arisen.
Quality control focuses on identifying defects in the final product or service through inspections and testing, while quality assurance involves implementing processes and procedures to prevent defects from occurring in the first place. In essence, quality control is reactive, while quality assurance is proactive in ensuring the overall quality of a product or service.
Quality control involves inspecting and testing products to identify defects and ensure they meet specific standards. Quality assurance focuses on preventing defects by implementing processes and systems to maintain consistent quality throughout production. In essence, quality control is about detecting and fixing issues, while quality assurance is about preventing them from happening in the first place.
Quality assurance focuses on preventing defects in the processes used to create a product or service, while quality control involves identifying and fixing defects in the final product or service. Both are important in ensuring overall quality, but they have different focuses and approaches.
Quality control focuses on identifying and fixing defects in the final product, while quality assurance focuses on preventing defects from occurring in the first place by implementing processes and procedures to ensure consistent quality throughout the production process.

Clearly, there are marked differences between quality guarantee and quality control. Assurance of quality is a set of preventive activities, which are focused on processes whereas quality control is a detection activity, which is focused on detecting the defects once the product is manufactured. Assurance defines the standards to be followed in order to meet the customer requirements whereas quality control ensures that these defined standards are followed at every step. This is done by conducting various tests and checks. Based on these tests and checks, the quality control prepares regular reports that act as an input to the assurance of quality department which then reviews the same and decides on the corrective and preventive actions required in the processes.
From my experience in QA, this is one of the most common misconceptions in the field - people think Quality Assurance and Quality Control are the same thing. They're absolutely not, and understanding the difference is crucial for anyone working in software development. Quality Assurance (QA) is proactive - it's about preventing defects before they happen. QA focuses on establishing processes, standards, and procedures that ensure quality is built into the product from the beginning. Think of it as creating a framework that makes it nearly impossible for bad code to reach production. Quality Control (QC) is reactive - it's about detecting and fixing defects after they occur. QC involves testing, inspecting, and validating the finished product to catch issues before they reach users. The key differences I see in practice: Timing: QA happens throughout the entire development lifecycle, while QC typically occurs at the end during testing phases. Focus: QA is process-oriented (how we build software), while QC is product-oriented (what we actually built). Approach: QA asks "Are we following the right processes?" while QC asks "Does this product work correctly?" Examples from my experience: QA activities: Writing coding standards, establishing review processes, creating test strategies, setting up CI/CD pipelines QC activities: Running test cases, performing code reviews, conducting user acceptance testing, bug reporting The relationship: QC is actually a subset of QA. You can't have effective quality control without solid quality assurance processes in place first. In practice, both are essential. Great QA processes reduce the number of defects QC needs to catch, but you still need QC as your safety net. Teams that only focus on one usually struggle with quality issues - either they're constantly firefighting bugs (weak QA) or they're shipping products with obvious defects (weak QC).
