CIDQ IDFX Exam - Topic 4 Question 23 Discussion

Posted by Telma on Jul 01, 2026 at 05:51 PM

After completing programming research for a private residence, what is the BEST tool for summarizing the spatial requirements?

Suggested Answer: A

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.

Verified Answer from Official Source:

The correct answer is verified using NCIDQ IDFX content on programming tools.

Exact Extract: The NCIDQ IDFX Reference Manual states, ''A criteria matrix is the best tool for summarizing spatial requirements after programming, listing each space's area and adjacency needs in a clear format.''

Objectives:

Use programming tools to summarize spatial requirements (IDFX Objective: Programming and Site Analysis).

Organize data for design decision-making (IDFX Objective: Design Process).

I think orthographic diagrams are more about representation than summarizing, so I would lean towards either the criteria matrix or stacking diagram.
AN

I feel like stacking diagrams are often used for visualizing space, but I can't recall if they are the best choice for this specific question.

I remember practicing with criteria matrices in class, and they seemed effective for comparing different needs, but I wonder if they really summarize spatial requirements well.
