This document discusses preparing for digital transformation through digital transformation modeling (DTM). It begins by outlining 7 metaphors - The Glass House, The Package, The Frog, etc. - to understand the impacts of changes driven by digital transformation. It then provides examples of how each metaphor could impact businesses. The document advocates for using DTM, which involves trend watching, defining business impact scenarios, and gaining insights, to help businesses prepare for an increasingly digital future and the ongoing changes it will bring. DTM can help identify where businesses may be disrupted and determine if they are ready to deal with issues like increased transparency, new competitors, and changing customer relationships.
