Product Policies¶
Status¶
Normative Business Domain Specification
Purpose¶
This document defines Product Domain policies.
Policies express business decisions that protect Product identity and consistency.
Canonical Identity Policy¶
A Product shall have exactly one Canonical Product Identity.
Identity may be incomplete during discovery, but it must remain explicit.
Silent identity replacement is forbidden.
Identifier Evidence Policy¶
Identifiers are evidence.
No Identifier shall define a Product alone.
Conflicting identifiers must create a Product conflict.
Observation Policy¶
Observations are evidence.
An Observation may support, enrich or challenge Product identity.
An Observation must not overwrite Product identity directly.
Variant Ownership Policy¶
A Variant shall belong to exactly one Product.
A Variant must not be shared by multiple Products.
Conflict Visibility Policy¶
Every contradiction between evidences shall become an explicit ProductConflict.
Hidden conflict resolution is forbidden.
Consistency Policy¶
Product consistency shall be derived from:
- identity completeness;
- identifier coherence;
- observation coherence;
- variant coherence;
- unresolved conflicts.
Boundary Policy¶
The Product Domain shall reject concepts belonging to:
- Offer;
- Catalog;
- Projection;
- Pipeline;
- Runtime;
- Adapter;
- Infrastructure.
Architecture Decision¶
