Subject: Re: [wsbpel-uc] Use Case Template

Sally et al:
Sounds like we are getting close to a template to try to automate the scripts to accomodate.  This looks like it includes most of what was in my swag a month and, better yet, adds to it.  Except for two things:
1.  Exception Handlers:  I think I'd like to see this included, as an additional interaction-type item, in addition to Expected Outcome and Alternative outcomes.
2.  Risk Factors: not a necessity I wouldn't think so can go away or be an option.

Subject: [wsbpel-uc] Use Case Template

Hi all-
My intent to put my thoughts re the revised template was interrupted by the blackout. Fortunately I was not in NYC on Thurs; so I missed the opportunity to sleep in Bryant Park which would hve been my choice over Grand Central. But we did lose power; it came back on Fri.
I agree with Harvey's point "for every abstract use case there is one or more executable use cases" . Because we are working with "ideas" the choice of words is important to insure that we are all on the same page.
I was OK with using usage sceario for high level use cases. As we move into specifics using the term use cases is probably necessary to get a broad understanding of what we need and are trying to do. My way of describing this is illustrated in the attachment DegreesOfUseCases.
I have revised the template; see the attachment. I agree with Harvey we need to relate use cases to its business process; and I also think we should indicate what aspect of the spec we hope to focus on with the particular use case.
I am also on the BCM TC. At a con call today David Webber said there was a template for collecting use cases being developed by the UN/CEFACT TMG. He forwarded it to me along with several commentaries from different people. I will forward this material to the group later today or tomorrow. Instead of thinking of it as innundation, I prefer to think of it as sharing the wealth. I have not had the time to read it.
I will read it and see if it helps sharpens the focus on what we are trying to do.
