Information architecture works at different scales
To evaluate an information architecture, first identify at what scale it operates. Information architecture generally applies to one of five scales: The organization, The platform, The site, The interface, or The interaction. At each scale, information architecture operates with different constraints. Each scale changes at different rates, and each scale operates within a different design context. Scale gives us a way to classify the type of information architecture, so we know what we can compare. Platform to platform and site to site.
