I regret creating this list with the name agile-usability... I'd just
came back from the UPA conference last year, and it seemed like most
folks there were comfortable referring to themselves as usability
people. I'm now seeing design - specifically user centered design,
interaction design, and user interface design as the big hole to be
plugged, and the activity that the usability people[?] are busy doing
on agile projects.
A few weeks ago I put out links to the stuff I'm working on. One big
point I'm trying to make is the /when/ you do things on agile
projects matters alot. Early discussions about UCD stuff on agile
projects dealt with the concern that doing design work took too much
time. That sort of thinking is wrong IMHO. I believe it operates
under the assumption that /all or most of/ the work is done up front -
so therefore our biggest challenge is figuring out how to do it
faster. [I kinda bristled at the title "Rapid Contextual Design" for
It's my experience that UCD /stuff/ by stuff I mean researching,
modeling, prototyping, testing, doesn't generally take too much
time. The agile projects I've been on really do have the time...
it's the _timing_ that's an issue. Some research and modeling needs
to be done ahead of release planning. Some decisions about workflow
and navigation structure should be made ahead of iteration planning.
UI prototyping should be ahead of storywriting. UI prototyping
doesn't need to be all completed before any code is written.
Navigation and workflow can change a bit at each iteration as we
learn more and functionality is added or changed. Models and
features can change periodically during and after releases as we get
feedback from using and testing the software we're building.
Basically, do all the same UCD stuff - just synchronize it with your
And, Hugh - to where your original comments were going, I see UCD
people as designers working in step with development, coaching
customers, developers, and business people. The usability thing is a
part of that that usually comes a bit later. And as to your change
in thinking comment - I find that whole projects become user
centered. This sort of thinking permeates every activity. Does that
square with your observations on your current projects?
My favorite story about this... on a project some years ago, we were working with a customer/UI design/user experience design team that interfaced with a development team in a very XP-ish kind of way, though it was not an XP project. After some time—enough time for everyone to get comfortable with the new roles—one of the developers on the user team came to us and said he was planning to go back to development. We were all worried and asked what was wrong and why he wasn’t happy. His response was, “I’m very happy but I like developing. Now that I’ve seen what you’re doing I know I can trust your process. So if you come and tell me to paint it purple, I’ll paint it purple because I’ll know you have a good reason for it.”
Moral being that the whole team may become user-centered in attitude—but part of that is knowing when to listen to the parts of the team that are more in contact with the user than you are. This is being duplicated in teams we’re working with now—the developers are getting to the point where they prefer to come to our folks rather than make off-the-cuff design decisions because they know we’ve got the closer user contact. Which—to bring the conversation back to XP—is as it should be.
