Coupled Architecture Without Independent Modules
The savings show up the moment a piece of the product is built as an independent module with a clean interface, meaning no dependencies on the rest of the system. The module can be rewritten without touching the rest of the product. New integrations elsewhere have a guaranteed zero impact on it.
Every future change to that module costs near zero hours of coordination. Change gets cheaper over time instead of climbing. The extra when that independence is missing is domain coupling.
