Quality Control is a crucial process in manufacturing and production that ensures products meet required standards and specifications. It involves checking, testing, and monitoring production processes to prevent defects and maintain consistent product quality. Think of it as a systematic way to make sure everything coming off the production line is exactly as it should be. Similar terms include Quality Assurance (QA), Quality Management, or Product Inspection. While these terms are related, Quality Control specifically focuses on the hands-on testing and inspection of actual products or processes.
