[Year 12 SofDev] basic agreed style rules for UCD

Surely if we all face the same exam, we need to agree on the same method -
or the rules for marking this type of question need to be released now.
Regards,
Russell Quinn

Dear colleagues
At the moment the scope of the use case diagram is identified in Bulletin Supplement, November 2010 http://www.vcaa.vic.edu.au/correspondence/bulletins/2010/November/2010NOVSUP2.pdf (page 5)
This scope should inform both the teaching and assessment practices for schools and for the Software Development examination. Shortly a set of sample examination questions will be published on the VCAA website and this will also assist in defining the depth of treatment.
Regards
Paula

Thanks, Adrian. IIRC, the system boundary is optional, and according to one source it's rarely used.
With all the flavours and styles of UCD, I'd like to see us settle on a standard style that we and the examiners will be happy with. A local style guide, sort of thing. That way we can more easily concentrate on the basic concepts and spend less time haggling about stylistic details.
In ITA we gravitated towards a simple, standard (activity on arrow), simple (no optimistic/pessimistic estimates) PERT chart that people were happy to use. We seem to be happy with our DFD rules and style. Having the same for these new UCDs would be a relief for many furrowed brows, I reckon.
Do people think this is worthwhile?

Hi Mark (and all),
Great diagram! There should be a system boundary around all of the use cases (representing RWT). I also think that the installer performing the installation is not really needed - but that's just my 5c! The diagram is also about as big as it needs to be really for a use case - as the tool is not intended to be used in a granular way (add another 2c - up to 7c now!)
Cheers,
Adrian

Hi all. Thanks to those (including Chris, one of our clever techies) for contributing to the UCD at
https://docs.google.com/drawings/pub?id=1qCkJ2EpprS28SoMZlz56xq3NzsdJWkqeL4J2rBgOWQc&w=2151&h=1019
(It's still open for editing - please annotate your changes to explain your logic).
It has grown into quite a complex beast... I'm not sure how many kids could handle something of that complexity in an outcome.

Thanks Paula. I did read the scope FAQ, and it was helpful. It was good to
see these issues being addressed explicitly and early.
What I was thinking about related more to UCD *style* rather than scope.
For example, in the Rivers Window Tinting UCD, should there be a use case
for an Installer actor and an "Install Tinting" use case? Although it's not
part of the system, it has been argued that it does lead to a system
connection with the customer approval and payment use cases, so it should be
there. (The argument came from a recent IT graduate who did a *lot* of UCD
work at uni.)
It would be nice if we had some basic agreed style rules for UCD as we do
for DFD. e.g. "Always include the system boundary box." "Always label
association lines if more than one actor is involved".
It would be excellent if authoritative sample exam questions set a preferred
style for UCD so they didn't have to evolve organically over time.
Regards
Mark
