AIAG-VDA Handbook compliance

Migrate your DFMEAs from AIAG-RPN to AIAG-VDA Action Priority — verified

OEMs are mandating AIAG-VDA migration through 2027. Specwarden ingests both AIAG-RPN 10-column and AIAG-VDA 16-column formats, detects which you're using, and flags rows where migration introduced AP-lookup errors.

How it works

Upload your DFMEA

Drop in your spreadsheet — .xlsx, .xls, .csv, or .docx. Specwarden detects AIAG-RPN or AIAG-VDA format automatically. No configuration.

Review runs in under 60 seconds

7 deterministic rule checks run first, then Claude Sonnet reads every row for supplier-blame causes, vague language, and missing rationale.

Why Specwarden for AIAG-VDA migration

Both

AIAG-RPN + AIAG-VDA in one tool

Submit your legacy 10-column AIAG sheet or the new 16-column AIAG-VDA format. Detection is per-file — one account, both formats, no configuration.

lookup-verified, not calculated

AIAG-VDA Action Priority is a table lookup, not a formula. Specwarden cross-checks every row's AP assignment against the §2.5.10 table and flags wrong values.

2027

OEM mandate timeline — verify now

Major OEM customers are enforcing AIAG-VDA migration through 2027. Specwarden verifies your migrated rows are correct before an auditor finds the discrepancies.

Migration verification features

Both formats, one tool

Submit your legacy AIAG-RPN sheet or the new 16-column AIAG-VDA format. Specwarden auto-detects which standard applies and runs the correct verification logic.

Action Priority (AP) lookup verification

The AIAG-VDA AP value is determined by S/O/D lookup table — it's not a calculated score. Specwarden cross-checks every row's AP assignment against the published table and flags discrepancies.

Migration-in-progress friendly

Working through a phased migration? Specwarden works on hybrid formats and flags which rows still use legacy RPN logic while the rest of the file uses the new AP column.

Built for engineering teams reviewing high-stakes technical documents.

Workflow proof

Reviews engineering documents against risk and compliance criteria

Use-case proof

Designed for FMEA, specs, quality checks, and design review workflows

Beta proof

Private beta feedback from technical reviewers and operators

The AP lookup table — simplified

Unlike RPN, Action Priority isn't calculated — it's looked up from this table. Specwarden cross-checks every row against it.

S	O ≥ 4	O 2–3	O = 1
9–10	H (any D)	H (any D)	H (any D)
7–8	H (D ≥ 5)	M	L
5–6	M (D ≥ 7)	L	L
2–4	L	L	L
1	L	L	L

Simplified from AIAG-VDA Handbook §2.5.10. H = High, M = Medium, L = Low. Detection (D) threshold varies by S and O band.

AIAG-VDA migration questions

Does Specwarden support the 2019 AIAG-VDA Handbook format?▾

Yes. Specwarden detects AIAG-VDA format from the presence of Action Priority (AP) columns and H/M/L assignments, and applies the AIAG-VDA §2.5.10 AP lookup verification logic.

Will it work mid-migration?▾

Yes. If your file has some rows using RPN and others using AP columns, Specwarden flags which methodology each row appears to use, helping you track migration progress.

What if my customers still use AIAG-RPN?▾

Specwarden supports both formats simultaneously. You can submit AIAG-RPN files for one customer and AIAG-VDA files for another — the detection is per-file, not per-account.
