Consolidating a Fragmented Fastener Supply Base
A contract manufacturer of outdoor power equipment buys 1,240 fastener SKUs from 17 distributors. Annual spend is $4.2M. Over the last 12 months the company recorded 38 line stoppages traced to fastener shortages, a 2.1% incoming defect rate, and 640 POs averaging $3,400. Three national distributors hold 70% of spend; 14 local suppliers hold 30% at unit prices about 6% lower but generate $180K per year in expedite freight. A line stoppage costs roughly $8,500 per hour and averages 2.5 hours. Engineering is resistant to changing approved part numbers. The VP of operations wants a recommendation before the annual contract cycle.
1. Build the total-cost comparison the team should use to decide whether to consolidate. What cost elements and data are required, and what does the current pattern suggest?

Start with a spend cube by SKU, plant, and distributor, then compare total cost of ownership rather than unit price:
- Price: the 14 local suppliers are about 6% cheaper on 30% of spend ($1.26M), a visible saving of roughly $75.6K.
- Freight: those same suppliers generate $180K of expedite freight, already more than twice the price advantage.
- Quality: at a 2.1% defect rate, require cost per defect (inspection, rework, scrap, returns), not just defect percentage.
- Downtime: 38 stoppages x 2.5 hours x $8,500 = about $807K per year. Even if only one-third is attributable to tail suppliers, the cost dwarfs the unit-price gap.
- Transaction cost: 640 POs x an estimated $75 to process = about $48K.
The pattern says the tail is being optimized on the wrong variable. Consolidation should be justified by availability and transaction simplification, not only price. Require 12 months of shortage, defect, and freight data by supplier before deciding.
2. Recommend a target supply base structure and the contract mechanisms that protect availability. Address the risk of over-consolidation.

Use a two-tier structure rather than a single distributor:
- Two national distributors split roughly 85-90% of spend, with the top 50 SKUs dual-stocked across both.
- One regional backup for critical and long-lead items, activated by explicit triggers.
- Local suppliers retained only for emergency or non-standard parts, with pre-agreed pricing.
Contract mechanisms:
- VMI or consignment for A-items, with min-max levels set from usage history.
- Service levels: 98% line fill, 24-hour emergency response, and credits tied to line stoppages.
- Quarterly scorecards covering fill rate, defects, lead time, and expedite frequency.
- Price protection or index clause for commodities, plus a right to audit.
Over-consolidation risk is real: a single distributor creates a new single point of failure. The dual national structure preserves leverage while keeping a credible alternative. Pilot on one plant before migrating all SKUs.
3. How should procurement manage the incumbent distributors and engineering during the transition?
Read the worked answer
Treat incumbents as transition partners, not losers. Segment them: national distributors get volume growth and clearer forecasts; local suppliers get a defined emergency role or an exit timeline. Communicate in person, give 60-90 days notice, and ask for a transition plan covering open orders and stock.
For engineering, do not reopen every part number. Use an equivalence process: identify the top 20 percent of SKUs by risk, run first-article and fit tests, and get written approval on alternates. Bring engineering the downtime and defect data, not a cost-cutting message. Set a joint transition team with operations, quality, and procurement. Track line stoppages weekly and hold a go/no-go review before cutting over the last local supplier.
