Architecture DDD

Overview

Use this skill to model complex domains so teams can evolve behavior without constant cross-team coupling.

Scope Boundaries

• Domain language differs across teams or subsystems.
• Invariants are hard to maintain because boundaries are unclear.
• A single model is causing conflicting meanings and high coordination cost.

Core Judgments

• Bounded context cuts: where language and invariants legitimately diverge.
• Aggregate boundaries: where consistency must be immediate versus eventual.
• Context integration style: ACL, conformist, published language, or shared kernel.
• Ownership model: which team can change which part without global coordination.
