AIAG-VDA FMEA Software
Qhubio is purpose-built for organizations working under the AIAG-VDA FMEA handbook. Generate Process FMEAs and Design FMEAs using the modern 7-step methodology, deterministic Action Priority calculation, and audit-ready documentation. Replace spreadsheet-based workflows with a structured system designed for automotive quality teams.

Why AIAG-VDA changed FMEA
The 2019 AIAG-VDA handbook fundamentally changed how automotive FMEAs are developed. The traditional RPN-driven approach was replaced by Action Priority, the workflow was reorganized into seven structured steps, and Prevention Controls were separated from Detection Controls.
The objective was simple: create more consistent risk decisions and reduce the variability caused by spreadsheet-based FMEA implementations.
| Legacy AIAG 4th Edition | AIAG-VDA 2019 |
|---|---|
| RPN driven | Action Priority driven |
| 5-step style workflow | Formal 7-step workflow |
| Mixed controls | Separated Prevention and Detection controls |
| Formula-focused | Risk-focused |
| High variation between companies | Standardized approach |
Why spreadsheets struggle with AIAG-VDA
Most AIAG-VDA implementation problems are not methodology problems. They are spreadsheet problems.
- Action Priority tables implemented incorrectly.
- Prevention and Detection controls mixed together.
- Inconsistent Severity, Occurrence and Detection scales.
- No audit trail.
- No reviewer workflow.
- No version control.
- No traceability between revisions.
During customer audits and PPAP reviews, these weaknesses become visible immediately.
How Qhubio supports the AIAG-VDA 7-step process
| AIAG-VDA Step | How Qhubio Supports It |
|---|---|
| 1. Planning & Preparation | Project structure, assumptions, baseline documents |
| 2. Structure Analysis | Process hierarchy and decomposition |
| 3. Function Analysis | Function mapping and requirements |
| 4. Failure Analysis | AI-assisted identification of failure chains |
| 5. Risk Analysis | S/O/D evaluation and AP calculation |
| 6. Optimization | Action tracking and moderation workflow |
| 7. Results Documentation | Excel and PDF export with revision history |
Deterministic Action Priority calculation
Action Priority is not a formula. It is a decision matrix.
Many Excel templates attempt to recreate AIAG-VDA logic using formulas, which often leads to incorrect prioritization.
Qhubio calculates Action Priority directly from the official AIAG-VDA decision table, ensuring that Severity always receives the intended weight.
| Scenario | S | O | D | RPN | Correct AP |
|---|---|---|---|---|---|
| Safety risk, rare occurrence | 10 | 2 | 2 | 40 | High |
| Functional failure | 8 | 4 | 5 | 160 | High |
| Moderate issue | 6 | 4 | 4 | 96 | Medium |
| Minor issue | 3 | 2 | 3 | 18 | Low |
Built for automotive suppliers
Qhubio is particularly suited for organizations operating within:
- OEM supply chains
- Tier 1 suppliers
- Tier 2 suppliers
- Machining operations
- Assembly plants
- Stamping operations
- Injection molding facilities
- Electronics manufacturing
The platform supports the type of documentation and traceability expected during APQP, PPAP and IATF 16949 audits.
