Systems Analysis Assignment - Specifying business rules

Related learning outcomes from the unit outline:

• Demonstrate evidence of the knowledge set and skill set required by the systems analyst.
• Apply structured techniques to the analysis of current systems and modelling of future systems.

Background: The objective of this tutorial is to provide you with practice in defining business rules. While the elaborated use case extended the description of the use case, it still remains unstructured i.e no clear inclusion of states, state changes, triggers etc. The business rules diagram that is then drawn to accompany the elaborated use case ensures that all relevant states, event, conditions and signals associated with a business rule are captured.

Task: For the add vessel and modify visit elaborated use cases provided, create business rules diagrams. For each work through the following stages:

1. What is the trigger?

2. What messages are generated?

3. What state changes occur?

4. What conditions are tested?

5. Of those conditions which can be checked by states?

6. What events can take place?

7. Connect up the constructs

Note: It is possible to follow a different order to achieve the same result e.g. the state changes could be identified first, then the events that allow the state transition could be added.
