User stories are short descriptions of features or functionality that provide value to end users. They are written from the perspective of the user and follow a standard template of "As a <role>, I want <goal> so that <benefit>". User stories should be independent, negotiable, valuable, estimable, small, and testable. They provide a way for customers to influence development without formal requirements documents. Acceptance criteria define how a story will be considered complete. User stories are used in agile methodologies like Scrum to plan and track work in sprints.
9. Negotiable - They are not written contracts or requirements that the software must implement. Story cards are short descriptions of functionality, the details of which are to be negotiated in a conversation between the customer and the development team.

Dependencies between stories lead to prioritization and planning problems. For example, suppose the customer has selected as high priority a story that is dependent on a story that is low priority.A company can pay for a job posting with a Visa card.A company can pay for a job posting with a MasterCard.A company can pay for a job posting with an American Express card.Suppose the developers estimate that it will take three days to support the first credit card type (regardless of which it is) and then one day each for the second and third. With highly dependent stories such as these you don't know what estimate to give each story—which story should be given the three day estimate?
