Can someone show me what a good dependency matrix looks like and specify why?

Question

I would like to start using DSM, but not sure how to get started.

What does a good dependency matrix look like and why? How does it work?

Answer 1

List the subsystems on the X and Y axis in the same order. Mark an "O" diagonally. Subsystems depending on themselves doesn't make much sense. Go vertically down the matrix. If that subsystem depends on the matching horizontal subsystem, mark an X.

A good one rearranges the subsystems to show patterns that might lead to a good refactoring.

I don't have one handy, though. Sorry.
