For PFMEA owners

Find your PFMEA audit risks in 60 seconds

Specwarden catches process-to-product contamination, missing reaction plans, and control method confusion in seconds. Built for manufacturing process engineers at Tier-2 and Tier-3 suppliers.

How it works

Upload your PFMEA

Drop in your spreadsheet — .xlsx, .xls, or .csv. Specwarden detects PFMEA format automatically from column headers. Works with AIAG FMEA-4 traditional layout.

Review runs in under 60 seconds

Deterministic rule checks run first (RPN arithmetic, field completeness, control method classification), then Claude Sonnet reads every row for process-to-product contamination and missing reaction plans.

Why choose Specwarden for PFMEA

D-101

process-to-product contamination — the deepest PFMEA moat

A PFMEA cause that blames design spec instead of a process parameter is an audit red flag. Specwarden detects this pattern across all process steps, even on rows where no one is looking for it.

D-103

control method classification catches

In-process detection masquerading as prevention inflates PFMEA quality scores. Specwarden cross-checks every Prevention Control cell for detection-language keywords.

Your PFMEA is parsed inside the request, then immediately discarded. Findings are delivered to your browser and stay there. We store counts and metadata only.

What we catch

Process-to-product contamination detection (D-101)

The most common PFMEA audit fail: a cause that blames a product design tolerance instead of a process parameter. Specwarden flags it every time and suggests the correct process-side reframe.

Control method classification (D-103)

Prevention vs Detection columns are frequently confused in PFMEA. "100% in-process leak detection" is a Detection control — not Prevention. Specwarden catches misclassifications that inflate apparent prevention robustness.

Reaction plan completeness on high-RPN rows (D-102)

High-risk PFMEA rows require a Reaction Plan — the operator's containment response when in-process controls fail. Specwarden flags every Sev ≥ 8 or RPN ≥ 100 row missing this plan.

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

Process-to-product contamination — the deepest PFMEA moat

When a PFMEA cause reads “design tolerance on shaft OD is too tight for our honing process,” that’s a product design problem — not a process problem. It belongs in the DFMEA. Specwarden flags this contamination pattern (D-101) and recommends the correct process-side reframe.

This is the check most generic AI tools miss because it requires understanding the semantic boundary between DFMEA and PFMEA scope — not just reading the text.

PFMEA review — common questions

What's the difference between DFMEA and PFMEA?▾
DFMEA (Design FMEA) analyzes failure modes in the product design — how a component can fail to meet its intended function. PFMEA (Process FMEA) analyzes failure modes in the manufacturing or assembly process — how a process step can produce a defective part. Specwarden handles both and auto-detects which format you uploaded.
Does Specwarden work on AIAG-RPN and AIAG-VDA PFMEA formats?▾
Yes. The traditional AIAG FMEA-4 PFMEA layout (with S/O/D/RPN columns) is fully supported and auto-detected. AIAG-VDA PFMEA format support is included — Specwarden detects the AP column and applies the correct verification logic.
Will it review my Control Plan?▾
Not in V1. Control Plan review is on the V1.5 roadmap. If you upload a Control Plan, Specwarden will flag that it's outside its current scope rather than trying to review it as a PFMEA.
Does it catch supplier-blame causes in PFMEA?▾
Yes, but differently from DFMEA. In PFMEA, a cause can legitimately mention incoming-material properties — the red flag is when the Recommended Action directs engineering to change the product design spec instead of tightening the process-side incoming-inspection. Specwarden (D-001b PFMEA variant) catches this pattern.
How does Specwarden handle in-progress actions in my PFMEA?▾
Rows with a future target date and empty revised ratings are valid in-progress state — Specwarden does not flag them. Rows where the target date has passed and revised ratings are still empty are flagged as stale (U-001 stale-action extension), consistent with AIAG-VDA §2.6.3 closed-loop validation requirements.
