Requirements Analysis Using Event/Response and Use Cases – Validating the Model

Planning

In the prior posts on “Event Discovery”, you completed your initial Event Model. I say “initial” because in the process of validating the model, you may discover additional events.

In order to validate the model, you first compare it to your Project Objectives (the implementation deliverables that survive and are maintained after the project is considered complete). For each Project Objective you need to ensure that you have one or more Events and Business Processes that will contribute to reaching that objective. If you don’t find at least one, you are missing at least one event and must cycle back to event discovery to find it or them.

When you are finished validating against the Project Objectives, you will then validate against the Business Objectives. As a reminder, Business Objectives…

  • Contribute to the business strategy
  • Make or save money
  • Take advantage of opporunity
  • Provide competitive advantage
  • Respond to new laws and regulations
  • Are measurable

Compare the Event Model against the defined Business Objectives and ask the Core Team and the Project Sponsor if this scope will directly or indirectly address the objectives. If one or more objectives are not addressed, then you will continue with event discovery until you are satisfied the Business Objectives are satisfied by the model.

In the next post I will present how Use Cases are derived from the Event Model.
