Whenever there is a need from the client or the customer, it has to be captured in some form, here we can TALK about product backlogs, and we capture the requirements in the form of user stories. It is one of the TECHNIQUES where the stories are added to the product backlog. The User Story is a tool used in Agile software development to capture a description of a software feature from an end-user perspective. It defines the type of user, what they want and why they want it, also it helps to CREATE a basic portrayal of a requirement. A user story template often uses the following type of format:

As a <role>, I want <feature> so that <reason>

The user stories are short enough to be accommodated in a sprint if not, they are further broken down into smaller pieces. It is written in a LANGUAGE which is UNDERSTANDABLE to both the client and the team, it is then the job of the agile team to take care of how to develop the code that will satisfy the requirements of the user story. To accomplish this, regular and close interaction is required from both the parties – the client and the team.
