Example Diagram

A wide variety of relationships can be shown on diagrams; you are not restricted to having a single element type or elements from a single phase on a diagram. This can help you to create appropriate relationships (such as Realize or Trace) to elements where no relationship was previously defined.

Consider the following diagram:

Traceability - Trace

Diagram Contents

The example diagram above shows how a series of requirements are traced to Use Cases and then Classes

The diagram instantly shows:

  • That two levels of Requirements are realized by Use Cases
  • Which Requirement is realized by which Use Case(s)
  • How some of the Use Cases are implemented by Class elements

You can drill down on each Use Case (or, in other Traceability diagrams, any other composite element) to display more detailed diagrams showing how the Use Case meets the Requirement; the Close Account Use Case, for example, contains a Communication diagram and a Sequence diagram.

You can tailor your Traceability diagrams to depict any level of granularity and any stages of development that are appropriate; for example, you might:

  • Narrow the above diagram to show development from just the Remove User Requirement, or
  • Extend it to include Interfaces, Components, Test Case elements or any other facet of the system or process


Building a Diagram

A number of tools are available to for creating diagrams that show traceability:

  • The diagram context menu Add | Related Elements option enables you to automatically bring in elements linked to the selected element
  • The Relationships window enables you to add elements to the diagram that are directly linked to the currently selected element
  • The Traceability window enables you to add elements that are indirectly linked

Insert Related Elements


  • Whilst the Traceability diagram itself provides information on the definition, design and implementation of a business process feature, much more information can be obtained using the Traceability tools
