Matrix Diagrams

A quality analysis tool that arranges information in a row-and-column grid to examine how items relate to each other. It makes the strength or weakness of connections among factors, causes, and objectives visible within the matrix structure.

Key Points

  • Displays relationships among two or more sets of items using a matrix layout.
  • Indicates relationship strength (for example: strong, moderate, weak) with symbols, numbers, or weights.
  • Common forms include L, T, Y, X, C, and roof matrices, chosen based on how many groups are being compared.
  • Helps prioritize work, reveal gaps, and assign ownership by clarifying where connections are strongest or missing.

Example

A project team maps customer requirements (rows) against proposed product features (columns). They mark strong links with a 9, moderate with a 3, and weak with a 1. The highest row totals show which features most strongly satisfy customer needs, guiding design priorities and trade-off discussions.
