I've been designing within the Agile/Scrum process for several years now. In my experience, it depends on the uniqueness of the feature in question.
If it's just another report submission page, for instance, the developers are usually happy with just a text listing of what's different, or perhaps a last-minute sketch on paper or a whiteboard. If it's a new kind of report, or a wizard, or some other non-trivial feature that doesn't have a twin within the existing software, I'll do a paper mockup one or two iterations ahead of time, and will do a DHTML mockup if there's any confusion about interaction points or flow. I've found that the process of creating and approving the mockup nearly always results in the discovery of a technical obstacle, an unconsidered change elsewhere, or realization from the product owner that the feature they've asked for isn't the one they wanted. So although the mockup itself is often possible to accomplish within an iteration, the other questions it raises need time to be properly addressed. If it's a radically new feature (e.g., introduction of spreadsheet entering into a formerly forms-only interface, or a redesign of the entire navigation system), I'll do paper mockups, DHTML prototypes, and an early round of usability testing before the release planning even begins. Those changes require buy-in from all of the product owners, and usually the executive team, and have no business being in development's queue until everyone is in agreement that the feature appropriately solves the strategic goals. Once the feature and its design are approved, only minor elaboration is needed during the development iterations. -Sarah Kampman -----Original Message----- Here's a question for you Agiler's%u2014where does prototyping fit into the Agile process? And what type of prototyping do you typically do, or feel is most effective for the Agile process? What about Scrum? . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
