Failure modes and effect analysis (FMEA)

 

 

This  approach  systematically  examines  the  failure  modes  of  each  component,  without however, focusing on relationships among the elements of a complex system.

 

 

Fault Tree Analysis (FTA)

 

A system  failure  is proposed  and  then  events  are  traced  back  to  possible  causes  at  the component level. The reverse of the fault-tree analysis is event tree analysis. This method most effectively illustrates the disciplined approach required to capture as much as possible of everything that affects proper functioning and safety of a complex system.
