Create a Component DFMEA

Learn how to set up a new Design FMEA document and configure the analysis structure for your component.

Link Design Characteristics to Failure Modes

Establish traceability between design characteristics and the failure modes they can experience.

Workflow Overview

Design FMEA follows the System FMEA in the V-Model decomposition hierarchy. Each component DFMEA documents how design characteristics might fail and what controls prevent or detect those failures. diagram

Key Concepts

Design FMEA focuses on:
  • Component-level failure modes derived from subsystem failures
  • Design characteristics that prevent or mitigate component failures
  • RPN scoring (Severity × Occurrence × Detection) both pre- and post-mitigation
  • Traceability to design requirements and test cases
Typical workflow steps:
  1. Create a DFMEA document for each component
  2. Identify design failure modes from the subsystem SFMEA
  3. Link design characteristics to failure modes
  4. Score RPN using the 9-view workflow
  5. Define design controls and verifications
  6. Update post-mitigation RPN after controls are implemented
System FMEA (SFMEA) analyzes system-level and subsystem functions. Design FMEA (DFMEA) analyzes the physical design implementation of those functions. DFMEA is always downstream of SFMEA in the V-Model.
