Use Case Diagram Template

The Use Case Diagram Template shows the various outcomes that can take place when a user interacts with a system, website, or product. Use this UML notation technique to develop dynamic systems that can respond intuitively to common user behavior.

Uses of Use Case Diagram Templates

In Unified Modeling Language (UML), use case diagrams show how system behavior can change based on user actions. Each use case depicts a possible scenario, which helps developers determine the functional requirements of the system.

Use case diagrams are a type of UML behavioral diagram, taking both internal and external actions into account. As our use case diagram example shows, the model may also incorporate time as a component because some system tasks are automatically initiated based on a scheduled timeframe.

Software engineers and web developers create use case diagrams to:

Plan out system architectures

Document dynamic system requirements

Visualize user goals and system flow

Develop and implement test cases

How to create your own Use Case Diagram

To make your own diagram, you’ll need to define the product goals and understand what outcomes a typical user expects when interacting with your system.

1

First, open the Use Case Diagram Template in Cacoo.

2

Use UML notation symbols to represent the ‘actors’ involved in the use case. Label each actor, such as customers and payment processors.

3

Now, add symbols to represent the structural system components involved in the interaction.

4

Next, label the use cases. Describe each potential action using the fewest words possible.

5

Finally, use arrows and other notation symbols to define the interactions between the actors and system components, as well as the resulting outcomes.

Collaborate with your team to perfect the diagram, so you can accurately depict how the system should function. With Cacoo, you can work on the diagram in real-time or add comments to share feedback and suggestions with key stakeholders.
