Utility and Warranty

You are considering creating a food truck locator app. Food truck owners would sign in on a website and enter their location. The app would deliver their location information on a map centered at the location of the potential food customer who is using the app. The scope of the app does not include ordering food from the food truck. For such an IT service to be successful, it must deliver both utility and warranty to its customers and create value for them. There are two types of customers: the food truck owners who enter the location of their food truck and the users of the app who are hungry.

Use your best professional writing skills to $(1)$ define utility from an ITSM perspective and to $(2)$ write a specific example of utility that would be delivered to food truck owners by a successful service.
