Product quality refers to the characteristics and features of a product that meet or exceed customer expectations. It encompasses various aspects, including durability, reliability, performance, and design. High-quality products often lead to customer satisfaction and loyalty, as they fulfill the intended purpose effectively. To assess product quality, companies may use standards and benchmarks, such as ISO 9001 or Six Sigma. These frameworks help ensure consistent quality control throughout the production process. Additionally, customer feedback and testing play crucial roles in identifying areas for improvement and maintaining high-quality standards in products.
