What is the difference between user stories and tasks in project management and how do they impact the overall development process?

User stories in project management are high-level descriptions of a feature or functionality from the perspective of an end user. They focus on the "what" and "why" of a requirement. Tasks, on the other hand, are specific actions that need to be completed to fulfill a user story. They focus on the "how" of implementation.

User stories help prioritize and communicate the needs of users, guiding the development process. Tasks break down the work required to implement a user story, making it more manageable for the team. Both are essential in project management as they ensure that the team is working towards meeting user needs and project goals effectively.
