USE CASES

Where this instrument fits.

  • Draft FMEA rows
  • Rank criticality by RPN
  • Prepare mitigation review
  • Export risk register rows
INPUTS

Required input fields.

  • Subsystem (required)
  • Failure mode (required)
  • Likely cause (required)
  • Effect (required)
  • Severity 1-10 (required)
  • Occurrence 1-10 (required)
  • Detectability 1-10 (required)
  • Mitigation (optional)
  • Verification (optional)

Data handling: this interface uses the L2ET protected same-origin instrument engine. Do not enter confidential, regulated, privileged, incident, medical or sensitive operational data.

METHOD

Inventory Table logic.

Calculates RPN as severity times occurrence times detectability and places the row into mitigation-priority bands.

Assumptions

  • RPN is a simplified prioritization device.
  • Severity, occurrence and detectability need expert calibration.
  • System interactions may change criticality.
INTERACTIVE INSTRUMENT

Flight/space FMEA table.

Use the controls below to generate a preliminary artifact. The output is intentionally bounded and requires human review.

OUTPUT ARTIFACT

Flight/space FMEA table.

The generated artifact includes findings, assumptions, limitations, recommended next actions and exportable structured output.

EXAMPLE

Example input and output.

Example input

Severity 8, occurrence 4, detectability 5 for power regulator failure.

Example output

Outputs RPN 160 with mitigation and verification plan fields.

LIMITATIONS

What this tool does not do.

  • Does not certify safety.
  • Does not replace full FMEA review.
  • Does not validate mitigation effectiveness.

This instrument does not provide legal, medical, cryptographic, engineering, regulatory or compliance certification.
