Final answer:
Customer stories are used in an XP process to capture customer requirements and prioritize features in software development.
Step-by-step explanation:
In an XP process, customer stories are used to capture the requirements or features that the customer desires in the software being developed. These stories are written from the customer's perspective and describe the functionality they expect from the software.
Customer stories are important in an XP process because they serve as a way to communicate and prioritize the customer's needs. They help the development team understand the customer's requirements and make informed decisions about what features to implement.
For example, in a software development project for a customer who wants an e-commerce website, a customer story could be 'As a customer, I want to be able to add items to my cart and proceed to checkout.' This story conveys the customer's desire and provides the development team with a clear objective to work towards.
