What is a Use Case Diagram?

A use case diagram is used to describe the possible usage scenarios that a system is developed for. In simple terms, it explains what a system should do. It also models which user of the system uses which functionality and how.

How to Create a Use Case Diagram Online with Your Team?

Open Creately and create a workspace to draw your use case diagram online and open the use case diagram shape library. Share the workspace with others you wish to collaborate with. Use real-time mouse cursors and synced previews to easily track the changes other participants make in the workspace.
Drag and drop the system boundary shape onto the canvas before identifying and adding the actors outside it. Actors can be a person, organization or another system which will be engaging with the system.
Identify the use cases or what the actors need from the system and the common functionality that can be reused across the system. Then identify the actors and the use cases that can be generalized
Once the diagram is complete, share the use case diagram with team members and ask for their feedback. You can use comments to carry out discussions and tag teammates to get clarifications.
Use version control to keep track of changes made to the use case diagram. This allows team members to see the evolution of the diagram and rollback to previous versions if needed.
Share the diagram with others either using a workspace share link or export it to a variety of file formats if needed. Alternatively, you can also use a secure embed code to embed the use case diagram in any site or intranet.
