## Description

Strategic DDD, bounded context discovery, context mapping patterns, subdomain classification, ubiquitous language, and organizational alignment

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Strategic DDD

Domain discovery and boundary definition at the organizational level. Strategic DDD answers: "Where are the boundaries?" and "How do contexts relate?"

## Subdomain Classification

Subdomains exist in the problem space. Classify before modeling.

| Type | Competitive advantage | Build or buy | DDD investment | Staffing |
|------|----------------------|--------------|----------------|----------|
| Core | Yes, unique differentiator | Build in-house | Full strategic + tactical | Senior talent |
| Supporting | No, enables core | Build (simplified) or outsource | Pragmatic tactical | Mid-level |
| Generic | No, commodity | Buy/integrate (Stripe, Auth0) | Minimal/none | Junior/integration |

**Decision heuristic**: If two competitors solve this the same way, it's Generic. If your approach gives you an edge, it's Core. Everything else is Supporting.

## Bounded Context Discovery

A bounded context is a software boundary within which a model is consistent. Different from subdomains (problem-space). They should align but are independent concepts.

### Discovery Techniques

**Language divergence** (primary signal): When the same word means different things to different groups, you've found a boundary. "Account" in billing vs. "Account" in identity. "Product" in catalog vs. "Product" in inventory.

**Organizational structure**: Teams that communicate frequently often share a context. Teams with formal handoffs often have separate contexts. Conway's Law applies.

**Consistency requirements**: Where true invariants must be maintained transactionally defines aggregate boundaries, which cluster into contexts.

**EventStorming Big Picture**: Domain events placed on timeline. When events cluster into distinct swimlanes with different actors and vocabulary, those are context candidates.

**Domain Storytelling**: Actors perform activities on work objects. When actors, activities, or work objects change meaning, you've crossed a boundary.
