Which of the following metrics is typically the most appropriate measure of product and service...

Customer perception is a crucial measure of product and service quality because it directly reflects the customer's experience and satisfaction with the product or service. Unlike internal inspections or product performance metrics, which are internally focused, customer perception captures the end-user's viewpoint. This includes aspects such as the product's ability to meet customer needs, reliability, ease of use, and overall satisfaction. Customer feedback, surveys, and reviews are common methods used to gauge customer perception and assess quality.
