Failure Mode Effects and Criticality Analysis (FMECA)

Carl S. Carlson

Open publisher page 4 citations

Abstract

Some companies choose to add or are mandated to add a Criticality Analysis to the failure mode and effects analysis (FMEA) procedure, according to specific procedures. This chapter introduces failure mode effects and criticality analysis (FMECA) and explains how it is different from FMEA. The criticality analysis is detailed here, including both quantitative and qualitative criticality analysis. Also included are an outline of FMECA history and specific FMECA scales, standards, and examples. The chapter then focuses on the unique aspects of FMECA, such as the standard, scales, and criticality procedure. Criticality matrix can also be used in quantitative criticality analysis in order to graphically plot item criticality versus severity. Controlled Vocabulary Terms critical path analysis; failure analysis
