Writing a Use Case Narrative for the Case Study
To practice writing a narrative, you will use the Use Case Fill Order in the case study Use
Case diagram from Session 6 presented in Figure 7-1. Given the description in the next
paragraph, you can draft a narrative for the FillOrder Use Case. Use the narrative elements
discussed earlier as a guide for organizing the narrative.
(From Session 6:)
FillOrder: This is basically your reason for being in business. Authorized personnel take
Product from inventory according to the order specifications. They update the order and the
inventory. If there are any items that can’t be filled, they create a backorder.

Figure 7-1 Use Case diagram from Session 6
The following section explains each of the fields of the narrative. The narrative begins in
Table 7-1 with four common audit fields to track the narrative document: the name of the
Use Case, a unique number (in case you need to change the name), the author of the narrative,
and the last time it was updated. You typically want to keep track of who is changing
the document, what they have changed, and when they changed it, to make certain that
everyone is aware of the latest revisions and to prevent confusion and unnecessary delays
due to misunderstandings.
