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.
SCAFFOLDING EFFECT

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
Use an N×N matrix to record information/material dependencies between elements; upper triangular coupling blocks indicate strong mutual dependencies that require repeated iteration. Rearranging the matrix to be nearly triangular can reduce feedback loops and shorten cycle time.
