Compare vendor cost with observed delivery and value
Keep invoices, usage, internal labor, credits, remedies and exit estimates separate before making a commercial decision.
Observe full cost
- Record cash and internal effort from identifiable sources.
- Missing cost remains unknown rather than zero.
Preserve credits
- Credits reduce observed cost but do not erase service failure.
- Separate negotiated remedy from verified value.
Compare alternatives
- Use current performance and exit cost when comparing renewal, renegotiation or replacement.
- Do not treat sunk cost as a reason to continue.
Retain the performance record
The Vendor Performance Studio keeps contract obligations, measured service periods, incidents, observed costs and owner decisions connected. It does not renew, replace, terminate, purchase or message.
