RE: [wsbpel-uc] Input on scenarios

[Harvey Reed <hreed@sonicsoftware.com>]

All,

Attached is the next rev of docs, where I took Sally's doc, and took into
consideration Simpl-eb and WSI use cases.

Here is where I think we stand:

1. We recognize that we need to start at a high level, then work down to
BPEL
2. We decided to focus on usage scenarios as high level and use cases as
technical. I added another higher level to group usage scenarios, I am
calling these "business flows" such as "replenish stock". There can be many
ways (usage scenarios) to replenish stock.
3. Within a usage scenario we will ultimately want to drill down to use
cases and BPEL. Here, we can take a usage scenario, and vary the
participants to test how invariant the BPEL turns out to be.

What is attached:

1. Guidelines - Our previous consensus for how to proceed
2. Catalogue - A proposed draft of a set of business flows, usage scenarios
and technical use cases. It is is not 100% complete, we should review before
proceeding. I incorporated Sally's template into this doc. Note also that we
can put any business eco-system assumptions into this catalogue, such as
assumed XML schemas, various actors, owned by legal entities, etc.

++Harvey

mm1: First, thank you for doing this Sally.  Secondly, on the template 
as provided:

    * Suggest alternate paths or flows not just outcomes. The use case
      may have some different events that impact the outcome. We need to
      document both.
    * May be associated with 0...n issues.
    * May also be associated with other use cases and usage scenarios
      (overlaps likely will occur).
    * Suggest you separate any notes/assumptions and requirements
      section.  Do we perceive the requirements to be only non-functional?

Thanks.
