Answer:
a. fit, timing
Step-by-step explanation:
A utility function can be defined as a measure of the benefits or satisfaction derived by the consumer of finished goods such as snacks, perfume, shoes, clothes, electronic gadgets etc.
Basically, a customer’s utility function typically refers to the welfare, enjoyment, benefit, usefulness or satisfaction a particular customer derives from a product or goods.
The dimension of timing and fit plays a very significant role in the process of adding value, benefits or satisfaction to a customer's experience.
By making many burgers before customers ask for them, a fast-food restaurant is sacrificing the dimension of fit and improving the dimension of timing in the customers' utility function.
