A Quality Management System (QMS) is a structured framework of policies and processes designed to ensure an organization consistently delivers products or services that meet both customer expectations and regulatory standards. By integrating core principles like quality planning, assurance, and continuous improvement, a QMS shifts the focus from merely catching errors to preventing them at the source. Ultimately, it serves as a strategic roadmap that drives operational efficiency, reduces waste, and fosters a culture of data-driven decision-making to enhance overall organizational excellence.
