Information Architecture Deliverables and Tinderbox
Deliverables in IA are always a challenge, and I suspect that Chris is right: one size does not fit all.
However, that doesn’t mean that there is no use in trying to make the documentation process more organic and efficient. I’ve long suspected that the missing link in our quest for this particular grail is the amazing Tinderbox: a freeform outliner that is also a mapping tool that also spits out HTML. I’ve used it to produce site mockups before, and it seems taylor-made for IA documentation.
