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. | For complex problems with a fuzzy situation, the method cleanly separates search space and decision. It first creates breadth in understanding and then focus in elaboration. This brings open questions, problem definition, and solution path into a traceable movement. | For a search for solutions with many degrees of freedom, a grid emerges for systematic combinations. The method separates features, variants, and exclusion criteria, so the space gets explored deliberately. | When a central question feels too large, the method breaks it into neighboring topic fields with their own depth of ideation. It holds structure and openness at the same time, so adjacent perspectives don't get lost. This grows an idea space out of a core problem. |
