Distinguish between quality assurance and quality control in tabular form

Quality assurance and quality control are two essential components of ensuring product or service quality, each with distinct focuses and methodologies. Quality assurance primarily concentrates on the prevention of defects by ensuring that processes are followed correctly throughout the production or service delivery cycle. It is a proactive approach, involving the entire team from top management downwards, and emphasizes the development of standards, process documentation, and preventive measures. The goal of quality assurance is to maintain consistent quality by adhering to predefined processes and standards.

On the other hand, quality control is concerned with the detection and correction of defects in the end product or service. It is a reactive approach, typically performed by a dedicated team, and focuses on product-oriented activities such as inspection, testing, sampling, and analysis. Quality control ensures that the final output meets specified standards and requirements. While quality assurance has a broad scope, encompassing the entire production process, quality control's scope is narrower, targeting the final product or service.

In summary, quality assurance aims to prevent defects by ensuring adherence to processes, while quality control aims to identify and rectify defects in the final output. Both processes are crucial for maintaining product or service quality, with quality assurance focusing on consistency and prevention, and quality control ensuring conformance to specifications.

Here's a tabular comparison between quality assurance and quality control:
