[Year 12 SofDev] UCD exercise and u3O1 assessment handbook as rubric

Tue Mar 1 10:44:33 EST 2011

Heya Lony and Colleagues,

I think the UCD exercise sheet is great. Practically telling them how to
draw the UCD is what many students need to start learning how to do
these. I keep emphasising that UCD and DFDs are tools that are meant to
make your life easier by illustrating what the system has to do and
giving you a plan to follow. I find students often get stressed trying
to work out where to start and your exercise will certainly help J.

Regarding case study writing, I would suggest not reinventing the wheel.
Past exams are a great source of case studies that you can generally
tweak to suit your needs. Even the old Info Systems exams have some good
case studies if you want to save the SD exams for revision purposes.

I have attached an assessment rubric based on (well copied from) the
assessment handbook. I began trying to translate it to first person to
make them easier for the students to read but have run short on time
this morning. It is still very generic and I'm trying to decide whether
to be more specific in the rubric about the requirements for a top score
or just include this in the SAC sheet.

Hi All,

I am trying to produce a Use Case Exercise Worksheet for my students.

The method I am using is to take the advice of Mark and reverse
engineering use case I find on google,

then tweaking it up so it is simpler for me and my students.

What I am struggling with is the art of writing a good case study or
scenario with depth of analysis.

Rereading my exercises makes me realise I practically tell them how to
draw the use case.

Any suggestions please?

Btw I distribute freely (if it is even wanted)

Kind Regards,

Lony Hem

Hello Michael, Mark and others

You may have come across this web site (agile programming - previous
study design). It shows one use of multiple boundaries, although not for
separating 'of interest' from 'not to be considered'. Rather, it uses
them to show development stages.

http://www.agilemodeling.com/artifacts/useCaseDiagram.htm

This one is interesting too. It uses boundaries to compartmentalise the
'system' but the paragraph leading into it suggests that this is not
strict UML convention

http://www.ibm.com/developerworks/webservices/library/ws-wsisamp/

and this uses multiple boxes to break down a complex set of interactions
(admin, server, browser, user) into two separate sets of interactions
(this whole tutorial is worth a read - someone from Carnegie Mellon so
it must carry some weight! Also, I am assuming <<uses>> is equivalent to
<<includes>>)

	G'day Michael.  Thanks for identifying the software - Paula was
interested in that sort of information.

	re. arrows: usually the primary actor (the one wanting response
from the system and initiates the transaction) has an arrow pointing to
the secondary actor (the one who provides a service to the system).

	The direction of the arrows is sometimes obvious (when the case
study is known), sometimes it's not.  A good skill is being able to
reverse-engineer a case study from a UCD.

	I've not met additional system boundaries before, so you could
be quite right.  Does anyone else have 2c to spend?

	Cheers
	Mark

	Yes I deliberately left arrowheads off the association lines.
Partly because I was following the example in Adrian Janson's book, and
partly because I didn't think it really needed them. I think the
direction of flow is obvious from the relationships.

	I believe that sub-systems can be represented by additional
system boundaries within the primary system boundary. But, if I am in
error, I should be grateful if anyone could definitively tell me so.

	Thanks Michael.  That looks jolly nice. What software did you
use to create it?

	I notice you don't put arrows on primary actor association lines
- is that deliberate?

	And the isolated box for installing the system - I haven't seen
that technique before.

	It does seem there's more that one way to skin a UCD.

	Another warning! I too am a first time poster on this list.
Here's a UCD I came up with for RWT. It perhaps has its short-comings,
but it might provide another way of looking at things. Let me know if
there are any glaringly obvious faults.
