# Sourcing strategies for hard-to-source spare parts

How Swiss companies reduce spare-part shortages: multi-sourcing, local stocks, supplier KPIs and contractual tools to shorten lead times and enable express delivery.

25 September 2026

## Quick answer

Short answer: Use multi-sourcing together with local spare parts stocks, standardized packing and shipping processes, and clear supplier KPIs and contract clauses to shorten lead times for hard-to-source parts. For urgent deliveries, plan express courier options from hubs like Zurich, Basel or Geneva.

## Why single-source strategies fail

Relying on one supplier or long global supply chains is fragile. Delays, customs or production issues quickly ripple into downtime. A resilient approach reduces dependency and improves response time.

## Multi‑sourcing: diversify while keeping control

Qualify at least two independent suppliers for each critical part, ideally from different regions. Use common technical specs and test protocols so parts are interchangeable. Keep framework agreements for price stability and allow short call‑offs for flexibility.

## Local stocks and consignment inventory

A small stock near your Swiss sites in Zurich, Basel or Lausanne shortens lead time. Consignment inventory at the supplier reduces capital tied up: you pay when you take parts. Combine safety stock with ABC classification to optimise working capital.

## Supplier evaluation and operational KPIs

Score suppliers on on‑time delivery, quality rate and emergency response. Run regular supplier reviews. Set KPIs such as OTD, defect rate and emergency reaction time. Link results to bonuses or escalation rules.

## Contractual tools to shorten lead times

Contracts can incentivise speed: SLAs for priority production, agreed express orders and penalty/reward clauses. Define order/change procedures and emergency contacts. Include escalation steps and clear responsibilities.

## Processes for fast physical delivery

Fast procurement still needs fast delivery. Standardise packing and handover so parts are shipment‑ready. Plan express courier services and night deliveries for urgent cases. In Switzerland, direct courier runs between production and service sites are often fastest.

## Frequently asked questions

When should I introduce multi‑sourcing? When a part is critical to operations or has long lead times. Start multi‑sourcing when downtime costs outweigh the extra management effort and price.

How much local stock is enough? It depends on consumption rate, procurement lead time and downtime cost. Use ABC analysis and hold safety stock for A parts, less for B and minimal for C.

Which contract clauses best reduce lead times? SLAs for priority production, agreed express orders, consignment inventory and clear escalation paths are most effective. Penalty/reward terms improve compliance.

How do I use express couriers for emergencies? Include courier options in emergency procedures. Agree on delivery windows and packing standards so suppliers can dispatch parts immediately with an express courier or direct run.
