As a purchasing director juggling multiple automation vendors, I've learned that certain red flags with PLC and servo motor suppliers should immediately trigger backup sourcing strategies. Here are the critical warning signs I watch for:

🚩 Delivery delays becoming a pattern - When suppliers consistently miss ship dates or extend lead times without clear explanations, it's time to activate your backup plan. This often indicates deeper manufacturing process issues.

🚩 Quality deterioration - If you're seeing more defective PLCs or servo motors, or if the products don't match approved samples, this signals potential process control failures that could escalate.

🚩 Communication breakdown - Suppliers who avoid sharing inspection reports, calibration certificates, or quality test results are hiding something. Transparency is crucial for critical automation components.

🚩 Financial instability signs - Payment term changes, sudden credit issues, or rumors of financial trouble should immediately raise alarms for mission-critical components like PLCs and servos.

🚩 Documentation gaps - When suppliers can't provide up-to-date production reports, maintenance logs, or compliance documentation, it indicates deeper management problems that could impact your production lines.

The key is having backup suppliers pre-qualified for these critical automation components. Don't wait until you're facing production shutdowns - when you see these patterns emerging, start activating your alternative sourcing strategies immediately.
