🧭 Which One Should You Choose?
| If you are… | Choose… |
|---|---|
| Focused on safety (ISO 26262) or system FMEA | APIS IQ RM |
| Running global projects with remote teams | PLATO SCIO |
| A small/medium company shifting from Excel | Knowlence TDC |
💡 Pro Tip: Start with a pilot project before a full transition. Many teams begin with Knowlence and gradually shift to APIS or PLATO as complexity increases.
🔁 Real-World Use Case
Tier-1 Supplier Use Case:
- Started with Excel → Shifted to Knowlence for AIAG-VDA compliance
- Expanded product platforms → Moved to PLATO SCIO for modular reuse
- Entered EV motor segment with safety goals → Adopted APIS IQ RM for system-level DFMEA + FMEDA
✅ Summary
Choosing the right FMEA software depends on your:
- Team structure (centralized vs. distributed)
- Product complexity (component vs. system)
- Compliance needs (IATF 16949, ISO 26262)
- Long-term scalability
🚀 Whichever tool you choose, it should support the AIAG-VDA 7-Step approach and improve collaboration, traceability, and audit readiness.
