Create a Use Case Diagram Book a Demo

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 by modeling the interactions between users (actors) and the system’s functionalities. It helps show which users perform which actions and how those interactions occur.

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

Open a Template

Launch Creately’s use case diagram maker online and start instantly with a pre-built use case diagram template. You can also try the dedicated shape library included in the use case diagram software to build from a blank canvas.

Customize the Template and Define Actors

Add the system boundary, update actor labels, and adjust the layout to suit your system. Apply color themes to distinguish between different actor types or system sections. You can also drag and drop additional actors such as people, organizations, or external systems manually.

Identify and Add Use Cases

Add use cases inside the system boundary to capture what the actors need from the system. Show reusable functionality with include relationships, and use generalizations where actors or use cases overlap.

Add Details and Collaborate

Use the notes panel or sticky notes to document requirements and clarifications. Share the workspace with your team, use real-time cursors and synced previews to track edits, and add comments or @mentions for contextual discussions.

Review, Update, and Share

Leverage version control to track changes and roll back if needed. Once finalized, share the use case diagram with a workspace link, export it to multiple file formats, or embed it securely in a site or intranet for wider access.
