No different for both if quality is applied in a process with " Do it right the first time" and understand the philosophy of "conformance to the requirement".
Philip Crosby a quality gurus has shared everything about quality.
different between quality control & quality assurance
A
Quality assurance is the process of detecting defects as products are being developed. Quality control is the act of detecting defects in already made products.
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

The quality assurance by PDSA cycle ensures that quality control, quality management system and construction process is maintained.
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.
* QA = Quality Assurance * QC = Quality Control
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 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.
