I am close to finishing the information architecture (IA) work for a large client project and have been using Omnigraffle for the first time.

While I am familiar with another product from their stable (Omnifocus) it took me a while to get used to this new one because it has such a different use. My choice of it was driven by IQContent (lead designers) as they used it for their initial IA overview.

However I am glad I made the effort because it made the visualisation of the site substantially easier. This is the format of the document it outputs.

I used colour coding for each layer of the site with the main navigation in green being successfully held to 5 choices and then each of those breaking down into upto 8 individual sections. The lowest level content (yellow) is very specific and limited to a relatively small user audience.

This document is used to drive:

• The requirement for content templates
• The allocation of sections to content editors for content preparation
• The identification of workflow paths with the new CMS
