Fae Intelligence · Root Cause Analyzer
Sample reports: one problem, every deliverable we offer
The same investigation (cold solder joints on QFN-48 packages, a fictional but realistic SMT reflow scenario) shown in each deliverable: Quick Root Cause (an NCMR), CAPA, and Full 8D. Every one is real, unedited output from the live tool, with a recorded production run behind it. We only publish samples we can trace to a real run. The analysis underneath is identical; what changes is the deliverable and who it's built to be handed to.
For each deliverable you can open the Report (the deliverable) or the Conversation (the full engineer↔tool dialog behind it, including the tool refusing a deliberately planted wrong theory). That conversation is the receipt.
Quick Root Cause Record
"Document the nonconformance and disposition it." An NCMR-compatible record: formal disposition + containment for internal QMS.
CAPA Record
"Corrective + preventive action built to FDA/ISO CAPA expectations," with effectiveness verification and closure criteria.
Full 8D Report
"The complete D1–D8 investigation in the structure your customer or auditor expects," with evidence matrix, fishbone with ruled out causes, verification experiment.

Why a generic AI chatbot is risky for root cause, and what this tool does instead
Pasting a defect into a general purpose chatbot has documented failure modes. As you read the sample conversations above, you'll see the tool resist each one. Watch for the 🛡 signposts in the dialog.
| What naive AI does | What this tool does |
|---|---|
| Agrees with your favored theory ("you're right, it's the supplier") | Pushes back and asks the question that could disprove it |
| Stops at one tidy cause that matches the timing | Holds out for the multifactor cause when the evidence demands it |
| Blames the operator; proposes "retraining" | Refuses operator blame and asks what the system allowed |
| Invents plausible sounding facts to fill gaps | Asks for missing facts, or marks them TBD. Invents nothing |
| Closes on correlation before anything is measured | Names the test/measurement still needed before it concludes |
| Fixes the cause; never asks why it wasn't caught | Names the detection/escape gap so it can't recur unseen |
The tool guides the process and enforces the discipline; your qualified person reviews and approves every result.
Pick by recipient, not severity: external customer or auditor → Full 8D; FDA/ISO CAPA with preventive action → CAPA; formal material disposition → Quick Root Cause. You can start light and escalate. Findings carry over.
These samples are AI generated drafts from a fictional scenario, shown exactly as the tool produced them. In real use, a qualified person in your organization reviews and approves every report before it is used.
