Purpose Whereas the primary goal of QC is to find and fix errors after they have already happened, the primary goal of QA is to stop problems from arising in the first place.
Focus Whereas QC focuses on the finished product or service, QA is more concerned with the production process.
Timeframe QC is a reactive technique that is often used at the end of the process, when the product or service is close to completion, while QA is a proactive approach that is employed throughout the whole development phase.
Methods Establishing and putting into practice a set of standards and procedures are part of the QA techniques used to make sure the product or service meets the specified standard of quality. Contrarily, quality control (QC) entails examining, testing, and confirming the product or service to make sure it satisfies the required standard of quality.
Goal For a product or service to continuously reach the desired quality level, a system of standards and processes must be established and maintained. Before a product or service is provided to the consumer, quality control (QC) aims to find and fix any potential flaws.
Responsibility The whole company, from the top management to the employees on the manufacturing floor, is accountable for quality assurance. The process as a whole is accountable for making sure the quality requirements are satisfied. On the other hand, the quality control team or department is in charge of QC.
Detection vs. Prevention By establishing methods and processes that guarantee the product or service complies with quality standards, QA is focused on avoiding problems arising. Contrarily, QA is focused on identifying existing flaws and fixing them before the delivery of the product or service to the consumer.

Documentation The documentation of the policies and guidelines put in place to guarantee quality is a component of QA. The procedure is regularly monitored and improved using this documentation. In quality control, problems are found and the steps taken to fix them are documented.
Cost Implementing QA may be expensive since it requires putting up processes and practices that make sure the good or service regularly satisfies the requirements for quality. QC, on the other hand, might be less expensive since it entails finding and fixing errors that have already happened.
