What is Quality Control (QC)?

It’s a process that evaluates all factors involved in production. It is an integral part of quality management and fulfilling quality requirements. ISO 9000 defines quality control as the review of all production factors to ensure the quality of a product. It’s an essential aspect of the manufacturing process. You must understand and implement all aspects of this process.

Quality Control QC is a necessary process that ensures a product meets requirements and is safe for use. It involves testing, statistical analysis, and inspection. The process of product inspection occurs at all stages of production. Inspecting the product will filter out defects and determine the root cause, which in turn will help you make improvements to the final product. If the process is done correctly, it can prevent costly mistakes and improve the final product.

When testing a product for defects, QC inspectors use one or more tools to evaluate the quality of the product. A bar graph is a fantastic way to see the frequency distribution of a given attribute. A quality control chart can be an X-Bar chart, which tracks the y-axis of the acceptable variance, and the x-axis tracks the number of samples tested. By looking at the pattern of the variation, you can tell whether a defect is occurring randomly or is caused by a systematic process.

Quality Management System – QA and QC Working Together

What Is the Difference Between Quality Control and Quality Assurance?

Both terms mean the same thing: ensuring that products are fit for their purpose. Aside from ensuring that a product’s design and features meet consumer expectations, quality assurance also works to ensure that processes are effective. The difference between these two concepts is not necessarily an important one, but it does matter in a business context. While quality control focuses on the end-product, quality assurance focus on the process and the factors involved in producing it.

While Quality Assurance QA seeks to prevent defects before they occur, Quality Control QC seeks to identify potential problems and correct them. The main objectives of both processes are to meet customer needs, and the two processes complement each other. Combined, these two processes lead to satisfied clients who repeat purchases, advocacy, and upselling. For this reason, the differences between Quality Control and Quality Assurance are significant. However, one fundamental difference between the two is that quality assurance is proactive, and QC is reactive.

While the two concepts overlap, they are entirely different. The goal of QA is to fulfill customer needs without substantial deviations or defects. To achieve quality, organizations must follow specific standards. In contrast, quality assurance is the goal of management. It gives customers confidence and security in a product or service. They can trust that the product or service will meet their needs. It is the difference between Quality Control (QC) versus Quality Assurance (QA).
