Architecture and Information Architecture

I just wonder how often there is a crossover between construction architecture and information architecture? On the receiving end of a presentation today about a new method of construction better practice approach, I was struck with how closely the aims and techniques matched with those of IA and user-focused design. I suppose this is not strange, in that, generically speaking, the more early planning you can pull into a project the more efficient an outcome is the usual result, and the sooner you involve all involved stakeholders in this, the better also (no matter what the field of practice).

The architecting and blueprint metaphors have probably become diluted over the past five years of IA practice as it has carved its own niche, but it's sometimes worth going back to the roots of the term - naming is a political action of choice, after all...
