Measure vendor concentration without false precision
Separate observed spend, operational criticality and practical substitutability before calling a vendor concentrated.
Map exposure
- Retain each vendor, service and observed annual cost.
- Do not treat missing spend as zero.
Add operational context
- Distinguish cost share from criticality and exit readiness.
- Keep irreplaceable knowledge and integrations visible.
Choose a response
- Mitigate, diversify or accept exposure through a retained decision.
- A concentration finding does not authorize replacement.
Retain the portfolio record
The Vendor Portfolio Studio keeps vendor evidence, dependencies, renewals, controls and owner decisions connected. It does not renew, replace, terminate, purchase or message.
