Balancing Coupling in Software Design: Universal Design Principles for Architecting Modular Software Systems

Appendix A

The Ballad of Coupling

Strong or loose, we live in dread,

Of the coupling monster under the bed.

Yet without it, your system would flake,

Coupling is a pillar you can’t forsake.

But if coupling isn’t the foe, then what can it be?

It’s complexity—the agent of anarchy.

To master the beast, its signs you must learn,

The Cynefin framework shows paths to discern.

Complexity rises, not from parts’ number or size,

It’s interactions among them, where troubles can rise.

While linear ones are simple and clear,

With complex interactions, failures loom near.

Modularity’s perks, we cannot ignore,

But its true essence, we still must explore.

What makes a design coherent and fluent?

It’s all about value—future and current.

Old paradigms fade, replaced ...
