One of the key consulting tasks with the implementation of e-Content Manager, or any content management system or web site implemenation, is Information Architecture. Without a good IA, users will not be able to get the most of your system and might even be driven away if the IA is very bad. Also, your staff will have difficulty in maintaining the information for which they are responsible since finding that information will be time-consuming with poor IA.
Boxes and Arrows is a great IA web site with lots of useful information: http://www.boxesandarrows.com/
In particular, I would recommed checking out this recent article: Change Architecture: Bringing IA to the Business Domain by Bob Goodman (http://www.boxesandarrows.com/view/change_architecture_bringing_ia_to_th...) As information architects, we are not just architecting information; we are using information to architect change. Bob Goodman shows us how we can use business and management techniques to help us be more effective agents of change.
One key message from all this is to not sell your IA short. No matter who sophisticated the software that is driving your web site might be, without proper IA people will not be able to find what they need, which means your web site has failed.
