After completing programming research, the designer needs to summarize the spatial requirements (e.g., square footage, adjacencies, and functional needs) in a clear, organized format. A criteria matrix is the best tool for this purpose, as it condenses the programming data into a tabular format, listing each space, its required area, and adjacency needs. This is particularly useful for a private residence, where spaces like bedrooms, kitchens, and living areas have specific requirements. Option B (rough floor plan) is a schematic design tool, not a programming summary. Option C (stacking diagram) is used for multi-story buildings to show vertical relationships, less relevant for a single residence. Option D (orthographic diagram) refers to technical drawings like elevations, not a summary tool.
