Creating Use Case Diagrams on Dragon1

The use case you see is created in the Visual Designer web application. You can create this use case diagram also directly in the Viewer. Just create a free account and you will be on your way in a few seconds.

What is a Use Case Diagram?

A use case diagram is a diagram that shows what user require from a system.

This example shows the requirements some actors have for a coffee machine that needs to be purchased or designed.

Use Case Diagrams are a wonderful tool for Enterprise Architects to collect requirements.

Strangely enough most Enterprise Architects do not create Use Cases.

The reasons behind that are probably:

  • They are not educated in Use Cases,
  • They do not consider that collecting requirements is part of their job,
  • They are not into creating diagram as a designer of total concepts.

In all three cases I would say: START CREATING USE CASE DIAGRAMS. Your stakeholdes will love it.

More Benefits with Use Case Diagrams

Did you know that you can show reuse of functionality on a Use Case Diagram? Or better: lack of reuse!

Did you know that you can reduce the complexity of a system design creating a Use Case Diagram?

This type of diagram, part of UML: the Unified Modeling Language from OMG, recognizes the following extensions: Include, Extend and Generalization. With these three extensions you can take all kinds of design decisions.
