Design Structure Matrix
Version 1.0.0 · Updated 2026-07-28
CORE DEFINITION
The design structure matrix (DSM; also referred to as dependency structure matrix, dependency structure method, dependency source matrix, problem solving matrix, incidence matrix, N2 matrix, interaction matrix, dependency map or design precedence matrix) is a simple, compact and visual representation of a system or project in the form of a square matrix.

The design structure matrix (DSM; also referred to as dependency structure matrix, dependency structure method, dependency source matrix, problem solving matrix, incidence matrix, N2 matrix, interaction matrix, dependency map or design precedence matrix) is a simple, compact and visual representation of a system or project in the form of a square matrix.
Anchor fast decisions
Also known as the dependency structure matrix, it uses a square matrix to visualize dependencies among system elements: rows and columns represent the same elements, and cells mark dependencies; below the diagonal are mostly feed-forward dependencies, while above are feedback dependencies that require iteration. The mechanism is to make implicit couplings explicit, and through matrix reordering, identify 'clusters (modules)' and 'critical coupling points'.
