Purposedifferent	ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification.	GAP Analysis compares the current state with a target picture and makes the distance manageable. It becomes useful when, ahead of new initiatives, it must become clear which capabilities, processes, or resources are missing.	The Blue Ocean Strategy Canvas shows how an offering is positioned relative to the market. Differentiation thereby becomes tangible in value factors instead of merely being claimed.	The Business Model Canvas condenses a business model to its key building blocks and assumptions. It makes variants quickly comparable and reveals gaps before validation or implementation begins.
