Excellent feedback Nate. I like the proposed set of examples. I think it will demonstrate the evolution of the use cases well. As outlined in the Guideline: Use Case Formats, there are also cases were less detail is required, so these examples will also fit well with that guideline. Cheers Chris

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 <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?

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 bugzillas: https://bugs.eclipse.org/bugs/show_bug.cgi?id=167924 https://bugs.eclipse.org/bugs/show_bug.cgi?id=168275 Thanks, Jim ____________________ Jim Ruehlin, IBM Rational RUP Content Developer Eclipse Process Framework (EPF) Committer www.eclipse.org/epf email: [EMAIL PROTECTED] phone: 760.505.3232 fax: 949.369.0720 -------------------------------------------------------------------------------- Telelogic Lifecycle Solutions: Helping You Define, Design & Deliver Advanced Systems & Software Learn More at www.telelogic.com Chris Sibbald Vice President, Standards and Technology Telelogic North America Inc. 255 Albert Street, Suite 600 Ottawa Ontario K1P 6A9 Canada Phone: +1 (613) 266 5061 Fax: +1 (613) 482 4538 Mobile phone: +1 (613) 266 5061 [EMAIL PROTECTED] http://www.telelogic.com Telelogic - Requirements-Driven Innovation! ------------------------------------------------------------- The information contained in this e-mail, including any attachment or enclosure, is intended only for the person or entity to which it is addressed and may contain confidential material.
