Chapter 33. Understand the relationship between the Services Inventory and the Vendors Inventory
Executive Summary: Chapter Overview
IF4ITThe Bottom Line
Core Concepts
| Concept | Definition & Strategic Role |
|---|---|
| Primary Vendor Relationship | For each consumed Service, the named Vendor providing the Service — connects the Service to the Vendors Inventory for joint analysis. |
| Fourth-Party Visibility | Subcontracted Vendors — the Vendors that the enterprise’s Vendors depend on — required by regulatory frameworks such as DORA, FCA Critical Third Parties, and APRA CPS 230. |
| Concentration Risk Analysis | Joint Service-Vendor analysis reveals concentration risks: many critical Services depending on a single Vendor, or many Services depending on Vendors that all share a single fourth-party provider. |

Services consumed from external providers are sourced from Vendors. The Services Inventory connects to the IF4IT Vendors Inventory and Attributes through the Primary Vendor and Subcontracted Vendors attributes in the Vendor and Supplier Attributes category. This relationship is meaningful for any Service the enterprise consumes — SaaS subscriptions, cloud services, managed services, professional services — and is the foundation of Service-level Vendor concentration analysis.
The relationship enables joint analysis of Service portfolio and Vendor portfolio that neither inventory could support alone. Which Vendors deliver which Services to the enterprise? Which Services depend on a single Vendor whose disruption would cascade across multiple consumer communities? Which Vendors are concentrated in delivering Services for a single Capability or Service Group, creating concentration risk invisible from either inventory in isolation? The Subcontracted Vendors attribute extends this analysis to fourth-party risk — the Vendors that the enterprise’s Vendors depend on — supporting compliance with regulatory frameworks such as DORA, FCA Critical Third Parties, and APRA CPS 230 that require fourth-party visibility.
