Failure Mode and Effects Analysis (FMEA, FMECA, RPN)


Identify the most critical failure modes

BQR’s FMEA / FMECA software helps to quickly import product trees, assign failure modes from libraries, define failure effects up to the system level, and complete a detailed analysis.



  • Identify single points of failure with high probability and severity to achieve high product Robustness, Reliability and Safety
  • Generate a failure modes database for troubleshooting and BIT (Built In Test) circuits design
  • Comply to authority’s requirements and regulations

Compliance to Standards

BQR’s FMEA / FMECA / RPN complies with the following standards:

  • Mil-Std-882E
  • Mil-Std-1629A
  • SAE J1739
  • IEC 60812
  • EN 50126, EN 50128 and EN 50129

Software includes customizable risk matrix, criticality, severity and RPN groups

How It Works

Steps for conducting Failure Mode and Effects Analysis using BQR’s software

Import (optional)

  • Import the block tree and components from BQR’s fiXtress using BQR’s Core Database or from CAD systems
  • During Import, the component failure rates, failure modes and ratios are automatically assigned

User Input

  • Define project data such as: Mission time, Severities and Risk Matrix according to required standard
  • Define functions and dispatch components to functions (automatically done if using CAD plug-in)
  • Define effects of each failure mode up to the system level
  • Define severity for each system level failure mode
  • Add additional mission phases if necessary
Failure Mode and Effects Analysis software
Failure Mode Effects


  • The FMECA software verifies the user data. If data is wrong/missing, user is notified
  • The software analyzes all possible failure paths and calculates the severity and risk for all failure modes and functions


  • Block and Mode criticality – for each severity and criticality group
  • Standard FMEA and FMECA reports
  • Summary of end effects
  • All reports can be customized
  • All reports are in Excel files
