Business Domain map

The 17 Business Domains of the OpenIM service-domain model, grouped by office tag and labelled with their Service-Domain counts. The graphical companion to the summary table in ../service-domains/INDEX.md.

Office tags are applied at Business-Domain level (not per Service Domain) — several Service Domains span offices, and forcing a per-domain office tag would break non-overlap.

Reading the diagram

• Front office (BD-01 to BD-06) — the investing chain. Strategy and allocation, security and manager research, direct and fund investment, portfolio construction, trade execution. The widest block — six Business Domains, 62 Service Domains — reflecting that the buy-side firm’s distinctive activity is investing.
• Middle office (BD-07 to BD-11) — control, valuation, measurement, compliance, treasury. The independent functions that price, measure, monitor and fund the front office’s positions.
• Back office (BD-12) — operations and servicing. The settlements / accounting / corporate-actions backbone. One large Business Domain (17 SDs).
• Cross-cutting — data (BD-13) — data, analytics and reporting as a horizontal layer the front and middle offices feed and consume.
• Cross-cutting — corporate (BD-14, BD-16, BD-17) — the firm-running capabilities: enterprise risk and assurance, governance and accountability, corporate services.
• Commercial (BD-15) — the client and commercial relationship: product, distribution, client management. Dormant for asset-owner archetypes; load-bearing for third-party managers and wealth managers.

Total: 17 Business Domains, 171 Service Domains.

What this diagram does not show

The diagram is the office-tagged Business-Domain landscape. It does not show:

• The Service Domains beneath each Business Domain. Drill into each per the links in ../service-domains/INDEX.md.
• The Service Operations beneath each Service Domain (third level, in each SD file).
• Inter-domain dependencies. Many flow from front-office decisions into middle-office checks into back-office settlement; the ownership map holds the cross-domain consumes / produces story at entity grain.
• The institution-archetype lens (which Business Domains an asset-owner / asset-manager / wealth-manager / hedge-fund / insurer activates). Recorded in each BD-NN README.
