Failure Mode, Effects and (Criticality) Analysis (FMEA/FMECA)

How can your system fail and what will the consequences be?

Safetec has extensive knowledge about and experience with Failure Mode and Effect Analysis (FMEA). We can show you where your technical system can fail, and help you improve your design.


No chain is stronger than its weakest link. Failure mode and effects analysis (FMEA) is a well-proven method for studying problems that may arise from single failures in technical systems. An FMEA becomes a failure mode, effects and criticality analysis (FMECA) if the criticality of the failure mode effects is analysed.

What we do

FMECA involves reviewing all relevant components of a technical system in order to identify failure modes and their corresponding effects. We will make ourselves acquainted with the system and facilitate a workshop with your experts where the complete system is reviewed systematically. For each component we will ask how it can fail and what the consequence of these failures will be.

Typical questions are:

  • What is the function of this component?
  • How can this component fail – what are the failure modes for this component?
  • What may the reason for this failure be?
  • How do you detect this failure?
  • What is the effect of this failure both locally for this component and for the system?
  • How probable is this?
  • How critical is this failure with respect to the system objective, production, safety of environment?
  • Are there any possible improvements in design that can help you avoid this failure?

The answers from these questions are logged in a table and the criticality of all failure modes is visualized in a risk matrix. In advance of the workshop we will together decide which combinations of probability and consequences are critical and which are not. The results will be presented in a report.

An FMECA is often the first step of a Production Availability/RAM-analysis.

Advantages and benefits

FMECA is a very systematic method to identify all failures and their criticality. Based on this analysis it is easy to prioritise design improvements or plan for maintenance and repair. Safetec shows you how to use this method to help you effectively systematise the information you get from your experts, and so help you improve your design. We combine our thorough knowledge of this method with our broad and long experience from studies on different systems from various branches.
