Quality Control
Emphasizes testing of products to uncover defects, and reporting to management who makes the decision to allow or deny the release.
Quality Assurance
Attempts 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 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.

different between quality control & quality assurance

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).
Quality assurance is the end result of a good quality control system. Basically, quality assurance means that the end user (customer) can be assured that the goods/service he paid for will be of high quality.
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.
The main processes in Project Quality Management are: quality planning and assurance, quality control and quality improvement
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.
The three spheres of quality are: Quality Managament Quality Assurance Quality Control
The quality assurance by PDSA cycle ensures that quality control, quality management system and construction process is maintained.
Quality assurance (QA) - Quality assurance is the process of auditing the results from quality control measurements to ensure that the quality requirements are being met. This process is used during the execution of the project. In most cases it is used alongside quality control. Quality control - This refers to monitoring and controlling the project results to ensure they meet the agreed-upon quality 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.
