Subject: RE: [wsbpel-uc] Input on scenarios
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 -----Original Message----- From: Monica Martin [mailto:monica.martin@sun.com] Sent: Sunday, August 10, 2003 4:06 PM To: wsbpel-uc@lists.oasis-open.org Cc: Sally St. Amand Subject: Re: [wsbpel-uc] Input on scenarios Sally St. Amand wrote: > Harvey and other UC subgroupies- > > As a follow on to my earlier email I am attaching a template that I > propose we discuss at our next subgroup telecon call.

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.
