<p class="MsoNormal" style="margin-bottom:12.0pt">Thanks, Kevork.<br>
<br>
The second link raises an interesting point when it says "For reasons that remain a mystery to me, many people focus on the stick figures and ellipses in use case writing since Jacobson's first book,
<i>Object-Oriented Software Engineering</i> (1993) came out, and have neglected to notice that use cases are fundamentally a text form."<br>
<br>
I must admit I've mainly stressed use case DIAGRAMS (UCD) with kids and spent little time on the textual descriptions of the use cases in the SRS. For the simple use cases we handle, I've found the UCD alone conveys all the necessary info, and giving textual
use cases as well is mere duplication of the UCD. In the SRS, I tend to gloss over the textual use cases section. My outcomes last year took this approach and VCAA said nothing about that being a problem when they were audited.<br>
<br>
The study design does not give much of a clue about the relative balance of use case text/diagrams, apart from requiring students to know use cases (SD U3O1 KK10) and the composition of an SRS (SD U3O1 KK12).
<br>
<br>
The detailed example for U3O1 mentions drawing a UCD. The assessment handbook's rubric for U3O1 says that "all relationships between users, the network, including data flows, and the proposed solution are accurately and clearly represented *diagramatically*"
(which to me suggests a CD/DFD and a UCD).<br>
<br>
Do you guys stress the textual descriptions of use cases in the SRS, or mainly rely on the UCD?
<br>
<br>
Just curious.<br>
<br>
Cheers<br>
Mark<br>
