FMECA, or Failure Mode, Effects, and Criticality Analysis, is a systematic approach used to identify potential failure modes in a system, product, or process. It evaluates the effects of these failures on system performance and safety, helping organizations prioritize risks based on their severity and likelihood of occurrence. The analysis involves several steps, including identifying failure modes, assessing their effects, and determining the criticality of each failure. By focusing on the most significant risks, FMECA enables teams to implement effective mitigation strategies, ultimately improving reliability and safety in various industries, such as aerospace, automotive, and manufacturing.
