User stories are an important part of the official business definition of purpose. They are used to capture the desired functionality of a product, service, or process. User stories are written from the perspective of the user and provide a concise description of the functionality that needs to be implemented. They are used to define the requirements of a project and to ensure that all stakeholders are on the same page. User stories are typically written in a simple, easy-to-understand language that is easy to communicate to the development team. They are used to break down complex requirements into smaller, manageable chunks that can be implemented in an iterative manner. User stories are an essential part of the development process and help to ensure that the end product meets the user’s needs.
