Key Differences Between Specifications and Implementations

Quick takeaway

Specifications and implementations share the same underlying structure — the difference is that implementations add client-specific information on top.

Feature	Specification	Implementation
Product Requirements	Yes	Yes
Modules and Entities	Yes	Yes
Fields and Metadata	Yes	Yes
Lineage	Yes	Yes
Measure Impact	Yes	Yes
Export	Yes	Yes
Notes	Yes	Yes
Client-Specific Information	No	Yes

A specification is the reusable product requirement set. An implementation adds client-specific information, implementation notes, and configuration context while retaining the underlying product requirements.
