Common mistakes
Too many items making the grid unreadable
No sorting for pattern discovery
History
Used in systems engineering and design structure matrices since the 1960s.
Accessibility notes
Pair fill (present/absent) with a redundant text or icon glyph inside each cell so the binary encoding survives a grayscale print or color-vision deficit. Provide a data table as alternative.
