on this list. I can understand the distinction you want to make, but
I don't think it's very helpful, especially on this list.
I understood "software development" to be a broad inclusive term, and
so covered, for example, UI designers: but you seem to be using it
simply to mean "programming". Is that right? It seems unreasonable to
me, as UI design work strongly affects the software. It also seems
unhelpful to put designing in a group with dreaming and
authorizing. Further, it seems silly to put UI design outside of
"Agile", when it has a process that is agile, and had it long before
that was common in programming.
In a group on "agile usability", you seem to be suggesting that the
main element of the process should be programming. I don't see how
that makes sense, when you have not addressed how usability happens.
I still see this area as new, and I don't think there is a widely
accepted way to bring UI design and usability testing together with
programming in an agile process. You seem to want to some strong
distinctions, yet I haven't seen any evidence that your approach leads
to good software that includes good UI design.
Have I missed something? Or is this word-play?

Here's an example taken from my contextual inquiries with translators.
We noticed that NOT ONE OF THEM used collaboratively built linguistic resources like ProZ, Wiktionary and OmegaWiki. That's not necessarily to say that collaboratively built resources would not be useful to them and that you should not build them. It may be that collaboratively built resources have just not made it into their world right now.
However, the CI observation gives us many useful information about how a collaborative resource should be built to serve the needs of translators. For example, we noticed that translators at least pay a lot of lip service to "trustworthy sources". So you know that with a collaborative resource where pretty much anybody can write content, you are up against a perception of lack of trustworthiness. At the same time, we noticed that when translators can't find a solution in trusted resources (ex: the terminology database of the Gov of Canada), they have no qualms about looking in less trustworthy resources, for example by doing a search on the internet. So, it could be that translators will be willing to use collaborative resources if they have more coverage than "trusted" ones. As the translators use the resource more and more, they will notice that they quality is high, and may get over the lack of trust barrier.
But all of that is of course hypothetical. They are hints that help you narrow down the search space. But a case like this, those hints are particularly important, because a wiki cannot be tested with individuals. It can only be realistically tested with a large community. It's like the WWW. You couldn't test the concept of the WWW without having a network of millions of interlinked pages already (although you could test the concept of a web browser on individuals). So, the only way to realistically test a wiki is to deploy it and see what happens. So the turnaround time for validating your decisions is longer. Hence the importance of having good a-priori data to guide your initial choices. Of course if you deploy something and it doesn't work, you should listen to what the community is telling you through their actual use of the real thing.

However, CI will also yield information that is pretty much independent of technology. For example, we have noticed that translators do not blindly trust ANY sources (even official ones like Gov of Canada terminology database), and will systematically consult at least two different resources to resolve any given translation difficulty. The only exception to that is when the translator hast the proper translation at the tip of his tongue, and uses lookup in a single resources to remember it. I'm being told that this behaviour was there already when translators used paper dictionaries only.
