Vendor underperformance typically begins with measurable drift in the first ninety days. Most organisations only act in the third or fourth quarter.
Why scorecards drift
Most vendor scorecards are built once and never enforced. They include the right metrics: SLA adherence, deliverable timing, cost variance, escalation count. What they lack is the connection between scorecard outcome and contract consequence.
A vendor that misses two consecutive quarterly targets faces a polite QBR conversation, not a corrective-action plan with a defined timeline. The scorecard becomes a record-keeping artefact rather than a governance instrument. By the time leadership notices the drift in audit, the vendor has been operating outside contract terms for three to four quarters with no documented warnings.
The QBR pattern that fails
Quarterly business reviews fail in a recognisable pattern. They are scheduled. They are attended. They produce a deck. The deck shows the same metrics drifting modestly each quarter. Both sides agree to "monitor closely". No corrective action is initiated, no escalation ladder is invoked, and no contract levers are referenced.
The QBR becomes ceremonial: a procedural review without governance authority. The vendor learns that the QBR is the upper bound of consequence. Performance settles at whatever level avoids the worst outcomes the vendor knows the buyer will tolerate.
A working operating model
Vendor accountability that holds requires five elements operating together. Removing any one of them collapses the system back to a procedural QBR.
One: scorecards with thresholds.
Every metric has a defined level below which corrective action is automatic. The threshold is not negotiable in the moment.
Two: corrective-action protocol.
When a threshold is breached, a written corrective-action plan is issued within ten working days with a defined remediation timeline.
Three: escalation ladder.
The path from operating-level disagreement to contract-level enforcement is documented before it is needed. Every step has a named owner and a timeline.
Four: contract levers referenced.
The contract clauses governing termination, fee reduction, and replacement are explicitly invoked in the corrective-action document. Not as threat. As record.
Five: cadence discipline.
The QBR is the review point. Corrective action and escalation operate continuously between QBRs. The QBR confirms what has already been resolved or escalated.
When to act
The cheapest correction is at week six of a quarter that is drifting. The most expensive is at month twelve of an audit cycle. Most organisations act in month nine, when the drift has compounded but before audit consequence forces the response. Acting earlier is a structural choice, not a cost choice.
Vendor governance without enforcement is reporting. Reporting without enforcement is theatre.
