Improving Supplier Performance

The challenge

An industrial manufacturer had long managed its strategic suppliers through periodic scorecards that arrived late, were disputed on arrival and changed very little. Suppliers experienced the reviews as a verdict rather than a conversation, and the buying team spent more time defending its data than acting on it.

The approach

The team rebuilt supplier reviews around a short set of measures agreed jointly with each strategic supplier, covering delivery, quality and responsiveness, and defined so that both sides drew on the same source records. Before any target was discussed, the definitions themselves were signed off.

Review meetings moved from backward-looking scoring to joint problem-solving. Each session closed with a small number of owned actions on both sides, revisited at the next review. Where the data pointed to causes inside the manufacturer, such as late forecast changes or unclear specifications, those were logged as buyer-side actions rather than quietly set aside.

What changed

Arguments about the numbers largely fell away once the definitions were shared. Recurring issues were resolved at their root instead of being reported again at every review, and several suppliers began raising early warnings on their own initiative. Category managers described spending their review time on improvement rather than reconciliation.

Lessons for practitioners

Agree what a measure means before agreeing what it should be. Be willing to record your own organisation's contribution to a supplier's performance problems, because suppliers notice when you do not. And keep the action list short enough that it is actually finished before the next review.
