[Year 12 SofDev] yet another UCD

Mon Feb 28 22:00:21 EST 2011

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.
