Re: [agile-usability] Automatic UI Generation
- Hi, Thomas. I'm a programmer rather than a UI person, so take this
answer for what it's worth.

developers who have shifted over to MBD tools. When I contrast this with
the rapid adoption of a variety of open-source tools and libraries, or
the recent rise of things like refactoring or unit testing, I suspect
that MBD is more the latest buzzword-compliant fad than an actual
movement. Of course, my sample isn't random, so it's perfectly possible
that I'm missing something.

prototypes are great. I have received excellent prototypes built up in
things like HTML and image files. Of course, I've also received
excellent prototypes on whiteboards and napkins. My concern with more
UI-specific prototyping tools (e.g., drag-and-drop builders) is that
they might constrain innovation as much as they would support it.
Again, this could be a function of the designers I happen to know, but
the best ones I've worked with all tend to use pretty general tools
(e.g., pencils, Photoshop). I've never asked why, but I'd guess that
they already have the knowledge of the domain that a more focused tool
would try to embody and their facility with general tools is such that a
specific tool doesn't get them much performance gain.
However, I'm very suspicious of any attempt to treat prototypes as
specifications rather than prototypes. The assumption behind a
specification is that thinking and learning are now basically done, that
all relevant factors are known and have been integrated. Perhaps one day
I'll see a specification where that's really the case, but so far I've
never seen one come close.
