An under-appreciated benefit of architecture modernization is the chance for semantic convergence (of your software and mental model).

It's common in legacy systems for words and concepts not to align with how people think and talk about the business.

It's also a potential pitfall. This better-aligned language tends to stimulate model innovation which can be a distraction from the modernization effort.

Yes, a bit of a double edged sword that one.

It's hard to avoid. As the business landscape evolves we don't update our code to match the business semantics, and new features get built on already-drifted semantics causing layering.

I refer to this as legacy-crystallized semantic drift.

As long as the product functions and adds new features, it's not seen as a problem.

Over time it can become a huge problem.

The effort to translate between business and software can become excessive. Especially for newcomers who have to learn 2 languages and how to translate between them.

One company told me it takes them weeks just to define requirements because it's so difficult to understand and determine what code needs to change.

When modernizing, don't miss out on the opportunity to modernize your domain model and benefit from semantic convergence.
