Purposedifferent | Wardley Mapping makes visible where an offering stands today and where it can evolve. The method connects user need, value chain, and evolution stages into a strategic basis for platform, build, or buy decisions. | For an event with a complicated course, the method breaks down the contributing factors along the timeline. It shows how conditions, decisions, and reactions together produce a course of events. | A Current Reality Tree condenses many symptoms into a few causal chains. The method makes visible which core problems drive several negative effects at once. | For a risk that can only be managed through multiple layers of protection, the method examines the effectiveness of each barrier. It shows where safeguards are missing, too weak, or fail under real conditions. |
