Sector Classification

Purpose

Sector classification describes the buyer-facing product or service. It does not describe internal architecture, value flow structure, or governance. Those questions are handled elsewhere in the framework.

Scope and Principles

Each system receives one primary sector and may receive up to two secondary sectors. Each assigned sector is then mapped to one or more corresponding subsectors.

• One primary sector per system
• Up to two secondary sectors where an additional service line is materially present today.
• Classification follows the dominant service delivered today.
• Buyer-facing economic signals determine classification — revenue, metered work, assets under service, binding commitments, or sustained usage
• In stacked products, the layer that is actually monetised or committed against is classified.
• Reward flows and token incentives do not override the buyer's job.

Examples in the sector catalogue and subsector catalogue are illustrative. A system may appear under more than one category where multiple service lines are material.
