The major enhancement I made by adding Contextual layer on top. Even though it sounds like hyper abstract on top of already abstract cake – I believe it deserves its place. Should we consider IM and IA from strategic performance management (SPM) viewpoint, it becomes imperative to bind Information Big Picture to business goals and direction.
Some years ago – even before I added the top layer, I thought, smart heads have already developed concepts for SPM – how could I utilize that fine work as aligning attributes for Knowledge Maps (or any other conceptual representation of information)? Then I ran into the Strategy Maps (Kaplan&Norton) and did few prototypes. It looks pretty promising to loosely bind Knowledge Map to Business.
