Quality control is a key aspect of any manufacturing process. It ensures a product’s conformance to regulatory standards and prescribed benchmarks. Quality control closely examines a product against its recommended specifications and highlights any anomalies or errors. Besides just examining the products, quality control can also be applied to assess the process of production itself. This can help identify inefficiencies or lack of precision across the manufacturing.
There are several approaches to quality control. Generally, the type of quality control tool used depends on the product that is being tested. Commonly used quality tools are scatter charts, fishbone diagrams, and pareto charts.
