This post is very difficult to understand, so here's my attempt at a simpler explanation. At some point in a project, somebody has to sit down, read through all the content and organize it. They have to gather all the information from the various groups involved and define how to logically break it down into separate pages. The define how users should navigate between them, what type of navigation is needed, etc. All decisions have to consider the various business, strategic and user goals, technical requirements, etc. These tasks have to be done at some point, and if there's no information architect, then somebody else has to do it (designer, developer, PM, etc). That's no problem for small projects, but it gets messy for large portals or big corporations where many stakeholders are involved.
