Introduction
In the Orthogramic, cross domain relationships are directional, typically flowing from active domains—such as Strategy, Capability, Initiative, Policy, and Stakeholder—to passive domains like Information, Performance, Product, and Service. This directionality ensures semantic clarity and consistency in modeling, visualization, and reasoning.
This page outlines the principles and best practices for modeling these directional relationships, helping you maintain structural integrity and enhance the interpretability of your business architecture.
Passive domains
Passive and Active domain concepts
Some domains are active — they initiate, drive, or own relationships (e.g. Strategy, Capability, Stakeholder).
Others are passive — they are typically referenced, used, governed, or measured. These domains do not initiate relationships.
The following Orthogramic domains are considered passive:
Domain | Typical Role in Relationships |
|---|---|
Information | Referenced by, used by, governed by |
Performance | Measured by, contributed to, indicator of |
Product | Delivered by, enabled by, rarely strategic |
Service | Implements, delivers, used in context |
...
It’s more accurate to say a Capability uses Information than to say Information informs Capability.
A Policy governs Information — not the other way around.
A Performance metric is influenced by Initiatives, not vice versa.
