Evans argues that developers must "knowledge crunch" by collaborating deeply with domain experts to distill complex business rules into a shared conceptual model. This shift ensures that technical implementations are a direct reflection of business reality rather than just a collection of databases and procedures. Strategic Design: Managing Large-Scale Complexity

As you begin to design the new features, you realize that the current system is a mess. The database schema is rigid, and the business logic is scattered throughout the codebase. It's hard to make changes without breaking something.

Here are some key takeaways:
