Facing the real problems first
Too many procurement teams pick systems by price or vendor promises and discover limitations on day one of production. Start by identifying the suppliers of medical device assembly automation you’re considering and map what can fail: validation gaps, spare-part delays, and integration mismatches. This article frames buying as solving those concrete problems, not choosing a shiny box.
Who will validate and document the process?
Ask if the vendor provides IQ/OQ/PQ packages tailored to your device and whether they’ll support documentation for audits. A machine that arrives without clear validation deliverables creates rework and regulatory risk. Confirm turnaround time for protocol updates when design changes occur.
Can the system meet your quality metrics without constant human fixes?
Request data showing defect rates, mean time between failures, and built-in error detection. Problems often show as intermittent defects; insist on objective metrics and traceability features. If a vendor avoids numbers, that’s a red flag.
How does the equipment handle regulatory change and traceability?
Probe for audit trails, electronic batch records, and change-control integration. Ask whether the system produces exportable trace data compatible with your quality management system. I’ve observed discussions at MD&M West in Anaheim where suppliers struggled to demonstrate traceability across legacy lines — don’t recreate that gap.
What happens to spare parts and service in your region?
Downtime kills schedules. Clarify local stocking, lead times, and whether certified technicians are available regionally. Check service SLAs, escalation paths, and remote-support tools. You need a practical plan for day-two uptime, not optimistic promises.
How adaptable is the line for product changes and volumes?
Ask for modularity specifics: changeover hours, required tooling changes, and software support for new recipes. Vendors should show how a single platform scales from prototyping to full production without wholesale replacement.
Who owns the code and control logic, and how is IP handled?
Clarify ownership of PLC and HMI code, access rights, and licensing. Insist on readable, well-commented code and a handover procedure. Vendors that lock code create dependency and future costs.
How secure is the system from cyber threats?
Demand details on network segmentation, authentication, patching policy, and secure update mechanisms. Automation equipment tied to your network is an entry point; require modern controls and a documented incident response plan.
What training and knowledge transfer are included?
Ensure the contract specifies operator and maintenance training, training materials, and competency checks. Ask for on-site shadowing time and a transfer schedule so your team reaches autonomy quickly.
Can the equipment integrate with your factory systems?
Confirm supported protocols (OPC UA, REST APIs, MES connectors) and ask for example integrations. Request a simple pilot demonstrating data flow between the machine and your MES. When vendors show working integrations, they’ve already solved much of the practical risk.
What total cost of ownership should you expect?
Push beyond purchase price. Get estimates for commissioning, validation, spare parts, consumables, service contracts, and planned upgrades. A low purchase price with high lifecycle costs is a common trap.
Common pitfalls teams trip over
– Accepting generic validation documents instead of device-specific protocols.
– Overlooking spare-part geography and assuming overnight shipping.
– Letting a vendor retain exclusive control of code and recipes.
– Skipping a live proof-of-concept run with your parts.
Watch for these patterns during vendor demos and insist on concrete remedies, not vague assurances.
How to use these questions in vendor conversations
Start with the hardest questions first — validation, traceability, service. Push vendors to demonstrate, not describe. Take notes during demos, request written evidence, and run a short checklist during factory acceptance testing. Practical answers will reveal capability faster than marketing gloss.
Conclusion: protect production and patient safety
Buying automation means solving specific operational and compliance problems. Ask the ten questions above, verify answers with evidence, and insist on clear handover to your team. Doing this aligns procurement with production realities and patient-safety obligations, a result I’ve seen repeatedly when procurement teams work with partners like FHS.
