| RE: [epf-dev] Looking for Use Case Templates & Examples |
|
Hello,
Attached is an example of the evolution of the use-case
model, including example use-case specifications, that I intend to include in
OpenUP/Basic. It uses the existing OpenUP/Basic template for the Use-Case
Specification, but illustrates that not all section must be
used.
This example has been attached to https://bugs.eclipse.org/bugs/show_bug.cgi?id=146443.
Please provide comments on that bug.

can be open sourced. The only wild card is the publisher Addison Wesley.

Everyone: After a week of living
the perfect storm, I’m back with the living and sifting through a very large
e-mail backlog. This e-mail caught my
eye because Paul Bramble, Alistair Cockburn, Andy Pols and myself wrote
“Patterns for Effective Use Cases” which contains numerous example use cases
written at different levels of details. Some of the examples may be helpful
here. Best
regards, Steve From:
epf-dev-bounces@xxxxxxxxxxx [mailto:epf-dev-bounces@xxxxxxxxxxx] On Behalf Of I provided some
feedback and change-tracked changes to the Word template, mostly to simplify it
and reduce the opportunity for bad practices by analysts who are new to use
cases (https://bugs.eclipse.org/bugs/show_bug.cgi?id=167924
). The excel-based
approach doesn’t seem like a very “elegant” solution to the valid problem of
shallow requirements management skillsets that you pointed out ( I commented
here https://bugs.eclipse.org/bugs/show_bug.cgi?id=168275
). It also seems to violate the “use simplest tools” philosophy.
Excel is more difficult to version control, since it has no merge
capability. It lacks “the power of plain
text.” For a lot of new
adopters, the paradigm shift isn’t having
use cases. Lots of big lumbering projects with three binders of
“the system shall blah blah” requirements also have “use cases,” but they treat them
as a kind of afterthought. The UP paradigm shift is doing use case-based
requirements, where the use cases are the primary way that we express the
functional intent we have for the solution. Treating use cases this way is
essential to enabling iterative development, because you can incrementally
refine a use case over time a lot easier than thousands of disjointed “system
shall” statements. So I’d suggest we
point adopters in the right direction with a series of use case examples at various levels of
specification. For example, we might have a use case that’s
just “identified,” then one with just the basic flow and a few special
requirements, and finally a fully-specified example. The purpose is to
demonstrate how you can incrementally refine the intent of the system based on
immediate goals. A classic example is Craig Larman’s “next-generation POS
system” in Applying UML and Patterns. Maybe he’d open-source the
examples? Thanks, Nate From:

all, We’ve been discussing how we can
make writing use cases easier for a wider range of practitioners, e.g.
experienced analysts, developers using use cases for the first time, old-timers
who are used to decomposing their requirements, etc. We think that offering a
variety of use case templates will help us in this endeavor, as long as we can
describe the best circumstances in which to use each
template. If you have any use case templates
that have been useful for you, please consider contributing them to
OpenUP/Basic. Attach any templates you’d like to contribute as a reply to this
email and we’ll consider them at the February F2F meeting this Thurs/Fri.
Examples of the two templates we’re
currently considering are attached to the following
