Answer:
reliability
Step-by-step explanation:
Reliability is one of the main objectives when it comes to good customer service. Besides the customer value and the quality associated with a particular product or service, it is important that the product is received or delivered in the expected time frame, which brings the dimension of time in customer service.
For example, we may order a pizza from a pizzeria that is well-known for the exceptional quality and taste of their pizza Margherita. However, if you order that pizza, and it arrives later than the proposed 45-min time frame, its customer value certainly decreases.
