Final answer:
Customers can contribute to product quality and service quality by providing feedback, suggestions, and referrals.
Step-by-step explanation:
Customers can contribute to product quality and service quality.
Product quality refers to the attributes and characteristics of a product that meet or exceed customer expectations. For example, if a customer buys a pair of shoes and they are comfortable, durable, and well-made, they would consider the product to be of high quality.
Service quality, on the other hand, relates to the level of customer service provided by a business. This includes factors such as friendly and helpful staff, quick response times, and efficient problem-solving. Customers can contribute to service quality by providing feedback, suggestions, or by referring others to a business with good service.
