Failure Mode and Effect Analysis or FMEA is a structured method to analyze component and system reliability. It is a framework to look at how something fails (failure mode) and what happens when it does (failure effect).

Basics

At a lay level, a FMEA should be a list of what-ifs, each "what-if" being looked at in multiple ways:

  • What will happen to the car if this thing goes wrong?
  • How likely is this thing to go wrong?
  • What can we do to stop this?
