About the Use Case Diagram Template
Miro’s use case diagram template is a visual tool that helps you analyze system relationships between personas and use cases — allowing your team to quickly illustrate system functionality.
These diagrams typically depict a system’s expected behavior, such as what will happen and when. It’s especially helpful because it allows you to design a system from the end user's perspective. In other words, it’s a powerful tool for communicating your desired system behavior in the language of the user by specifying all externally visible system behavior.
Generally, use case diagrams are not very detailed. They contain just the essential information that helps represent the goals of system-user interactions, define and organize the functional requirements in a system, specify the context and requirements of a system, and model the basic flow of events in a use case.
How to fill in the use case diagram template?
Creating and sharing your team’s own use case diagram is easy using Miro. Start by clicking on the blue “use template” button to open the use case diagram template in Miro, then follow these steps:
1. Identify your actors
Actors are anybody interacting with your system. An actor can be a customer, user, person, system, or organization. To add them to the use case diagram template, double-click on the text boxes labeled “name” to replace the content with your own.
2. Identify use cases
A good rule of thumb is to start by asking what actors need from the system. For example, at a library, actors need to pick up books, return books, get a library card, reserve rooms, and use the internet. These are all types of use cases. Once you know what yours are, double-click on the text boxes labeled “use case” to replace the pre-written content with your own.
3. Identify generalizations
Are there any associated actors who trigger similar use cases unique to them? Generalize that particular actor. A common example is the “make a payment” use case in a payment system, which generalizes three similar use cases such as “pay by debit card,” “pay by cash,” and “pay by credit card.”
4. Connect actors and use cases
Use the connection lines on the use case diagram template to represent the interactions between actors and use cases. Click and drag them to adjust where they link to — and duplicate or remove them as needed.
