Quality models are frameworks used to assess and improve the quality of products, services, or processes. They provide structured criteria and guidelines that help organizations identify strengths and weaknesses, ensuring that they meet customer expectations and industry standards. Common examples of quality models include the ISO 9001 standard and the EFQM Excellence Model. These models often focus on various dimensions of quality, such as performance, reliability, and customer satisfaction. By implementing a quality model, organizations can enhance their operational efficiency, foster continuous improvement, and ultimately achieve better outcomes for both their customers and stakeholders.
