Supplier Improvement Plan

This plan handles sustained underperformance by an approved supplier you intend to keep. It sits between the measurement that found the problem and the decision to keep or exit. Used for the wrong kind of problem it produces records that neither close nor report cleanly.

ISO 9001 cl.8.4 requires that control of suppliers is proportionate to their effect on conformity, and that performance is evaluated and acted on. The mapping below shows where each obligation is met in this template.

Supplier performance is rarely regulated directly, but three regimes make a dated, documented plan the difference between a defensible position and an unevidenced one. Which applies depends on what you buy and who you sell to.

Most of this template is factual. Four judgement calls decide whether the record holds up when the relationship goes wrong, and all four are made before signature rather than at closure.

These findings recur when improvement plans are sampled in a certification or customer audit, with the field that should have caught each one.

A contract packer opened a plan on a carton supplier after three consecutive scorecards below 80 per cent on delivery reliability. It named eight actions, all owned by the supplier's operations director, and set a review every eight weeks. The first two happened. The third moved for a holiday, the fourth was covered by email, and after that the plan simply sat open at In progress.

It surfaced twenty-two months later when a customer's auditor sampled the supplier file and asked what the plan had achieved. There was no Score After, no record of reviews after month four, and no escalation, despite the scorecard having fallen further. The finding was not that the supplier performed badly — that was documented. It was that the buyer had a known problem, a documented commitment to manage it, and no evidence of having done so. The plan had become the nonconformity.

Writing the plan is an afternoon. Holding the review cadence for two quarters, keeping the evidence attached and escalating on time is what decides whether the record is worth anything.

KnowLogistics

Owns the supplier lifecycle: raises the plan from a failed scorecard, keeps it linked to the vendor register, and blocks closure without a Score After against the baseline.

KnowQuality

Carries the quality side of the case — corrective requests, audit findings and rejections — and pulls them into the evidence trail rather than a separate file.

KnowComply

Handles plans raised for due diligence rather than quality reasons, keeping timelines and indicators in the form regulators expect to see.

Ella

Watches review dates, flags plans whose Next Review Due has passed with no review recorded, and holds every write for your approval before it touches a record.

Baseline

Performance at the point the plan opens, captured in Score Before and taken from the linked scorecard rather than recalculated.

Joint agreement

Confirmation the supplier proposed or accepted the actions rather than receiving them as an instruction. Material to any later termination.

Escalation

The step taken when the plan stalls rather than fails outright: reduced volume, applied conditions, or referral to offboarding via Offboarding ID.

Sustained improvement

Performance held at the agreed level for a period after closure, rather than achieved once at the final review.

Completeness percent

How much of the template was answered, held apart from the score so a high result on a half-completed plan is visible as such.
