Comparison of Use Case and User Story
Disappeared Use Cases have become a project management holdover, replaced by improved User Stories, but each has its own benefits.
A Use Case refers to the functional interaction of a user with a system based on a specific set of scenarios. A User Story is a desired view of the system for a particular stakeholder who needs certain functionality to achieve their own goal. Acceptance criteria are implemented through preconditions, actions, and results.
There are similarities in role presence, where the use case is about user actions and the user story is about getting value for the user. In the user story, there is more emphasis on obtaining value as a key aspect, and in the use case, it is behavior. A user story leaves out unimportant details unless they are spelled out separately. The use case entails scheduling the entire script. The user story places emphasis on understanding the business, while the use case is based on understanding the team.
During user story change management, old requirements are not changed, and new user stories are created. Use Case requires most of the existing scripts to be changed.
A user story has no general understanding of how the functionality works. There are many third-party tools for user story management in the form of tasks, prioritization, and control. The main difficulty lies in tracking the impact of changes on each dependent task. However, it is easier to manage changes as new tasks are created. A user story is represented as a small atomic artifact that is easier for the business to approve.
Changes to the use cases are difficult to manage because they affect the rest of the feature branch. High support costs, as resources are spent on its competent integration with the rest of the system. A plus is a complete description of the system. The interaction between each change is visualized.
The user story is great for backlog management. Use Case is a great knowledge base for developers. In the case of combining approaches, Use Case 2.0 is obtained, in which the use case is represented by a common front of the work path and the user story is a unit of work, including one scenario.
User Story
Cons:
• There is no overall picture
• There are a lot of smaller artifacts that need to be managed
• It is difficult to track the impact of changes on related functionality
Pros:
• Small artifacts come for approval
• Just manage the changes
• Well suited for incremental development
Use Case
Cons:
• It is difficult to manage changes
• Large labor costs for support
• If the development of the change is postponed, it is difficult to manage the relevance of the document
Pros:
• Full description of the system
• It is easier to analyze the impact of changes
• Easier to manage project boundaries
Application
• Set a task for development — Use case and User story
• Define test scenarios — User story
• Set a task to change — User story
• Provide application support — Use case
