Understand the relationship between the Capabilities Inventory and the Vendors Inventory

Vendors materially support delivery of Capabilities through products, services, or outsourced work. The relationship complements the Outsourcing Provider attribute in the Vendor and Supplier Attributes category — the Outsourcing Provider attribute names a single principal vendor for fully outsourced Capabilities, while the Related Vendors relationship captures the broader set of vendor dependencies including software vendors, infrastructure providers, and specialized service providers whose products materially enable the Capability. The Vendors Inventory and Attributes is the published companion inventory to which these vendor relationships link.

The Related Vendors relationship attribute in this inventory is populated from Vendor records in the Vendors Inventory that reference each Capability. The relationship enables Capability-level vendor concentration analysis: which Capabilities depend on a single vendor with no viable alternative? Which Capabilities are exposed to a vendor whose financial health is deteriorating? Which Capabilities depend on vendors whose contracts are due for renegotiation?

Capability-anchored vendor analysis is qualitatively different from application-anchored or contract-anchored vendor analysis. It surfaces vendor dependencies at the business-outcome layer, which is where strategic vendor decisions are most defensibly made.
