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 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.
