Supplier Development

A supplier is causing you problems — defects arriving, deliveries missing dates, inventory held as insurance against their unreliability. The options look like two: tolerate it, or replace them.

Both are expensive. Tolerating it means you keep absorbing the cost, and it accumulates quietly in inspection, sorting, expedited freight and safety stock. Replacing them means qualification, tooling, first articles, learning curve, and a real chance the replacement performs no better — because the problem may not have been that supplier specifically.

Supplier development is the third option: making the supplier's performance better by giving them what they need to succeed in your supply chain. It is usually the cheapest of the three, and it is the one most organizations never seriously consider — partly because it requires accepting that some of the cause may be on your side of the relationship.

We use QSE's Ten Step Approach™ to Implementation, applied to the supply base rather than to your own plant:

• Supply base assessment — establishing where the cost actually sits. It is rarely spread evenly; a small number of suppliers usually generate most of the loss.
• Selection of development targets — suppliers where the volume, the gap and their willingness make improvement worth the investment
• Joint problem definition — with the supplier, not delivered to them. This changes the whole character of the engagement.
• Root cause work on the actual defects and delays, frequently revealing that specifications, forecasts or drawings on your side are contributing
• Quality and lean tools transferred to the supplier — SPC, error-proofing, changeover reduction, problem solving
• Knowledge sharing across the extended enterprise — deliberately sharing what you know so the supplier can perform
• Measurement against an agreed baseline, so improvement is demonstrated rather than felt
• Documentation so the gains hold when personnel change

The knowledge-sharing element requires a decision from you. Real supplier development involves accepting calculated risk by disclosing information — process detail, forecasts, sometimes proprietary knowledge — to enable mutual growth. Organizations unwilling to do that can improve supplier compliance, but not supplier capability.

Across this work, clients typically achieve:

• Inventory cost reduced by 25–50% — the largest single gain, because most inventory is insurance against unreliability, and reliability removes the need for it
• Sourcing time reduced by 25–30%
• Time-to-market improved by up to 20%
• Fewer defective parts arriving, and less inspection and sorting on receipt
• Improved responsiveness to your customers, because your own delivery performance depends on theirs
• Stronger supplier partnerships that survive commercial pressure

The inventory figure is the one that usually funds the programme. Safety stock exists because someone does not trust a supplier's delivery or quality — remove the cause and the working capital is released, permanently.

There is a strategic dimension too. Suppliers who have been developed rather than squeezed treat you differently when capacity is tight, when a rush order is needed, or when a competitor approaches them. That is not sentimentality; it is what a supply chain built on relationships rather than transactions actually delivers — and it is exactly how QSE's own business has worked for thirty years.

It suits organizations that want to:

• Reduce cost while cutting defective incoming product
• Strengthen supplier partnerships as a competitive advantage
• Share knowledge across the extended enterprise
• Accept calculated risk in disclosing information to drive mutual growth

Where it fails:

• Where it is run as an audit programme — assessing suppliers and issuing corrective action requests is supplier management, not development, and it does not build capability
• Where the buyer will not examine its own contribution — unstable forecasts, late engineering changes, ambiguous specifications, unrealistic lead times
• Where development is offered while price pressure makes investment impossible for the supplier
• Where the supplier is unwilling, in which case re-sourcing genuinely is the answer
• Where no baseline is measured, so nobody can show what changed
• Where effort spreads across the whole supply base instead of concentrating on the suppliers that matter

We bring 30+ years and 900+ organizations to this, with the standards context — ISO 9001, IATF 16949 supplier development requirements, and ISO 28000 supply-chain work — behind it.
