Most organizations vacillate between two extremes. Either they institute too much structure and control with bureaucracy (see the Rational Unified Process) and inflexibility, or they allow too little control or structure (take your pick - Pets.com or WebVan, anyone? Suggestions welcome).
Information Architecture can create a "loose" structure(s) that:
- Frames the problems, opportunities, and constraints
- Allow for varied perspectives (of both project stakeholders and the end-users)
- Removes much of the politics from the decisions made in the project
- Maximizes the benefit for everyone
Come on, let's prove that one!
