Six Sigma Improvement Tools: Failure Mode and Effect Analysis (FMEA)

Posted in Lean Six Sigma

Besides CNX diagram (Fishbone diagram) and Pareto diagram, there are other ways to determine the significant Few opportunities is by FMEA. Pareto diagram requires a lot of data variations to determine the factors that most influence on an event / process. If the data is not possible then the results obtained will be raw and less satisfying. For that use of FMEA is strongly recommended.

The use of FMEA in the beginning was the maintenance of industrial safety or reliability, but later widely used in various processes. From the FMEA results, improvement priorities will be given to components that have a priority level (NDP) the highest.

FMEA is made in tables consisting of columns as follows.
Component: The component to be studied can include machines, processes, etc.
Failure Mode: The model of the failure is often the case.
Failure Effect: the impact if a component called the failure modes fail.
SEV: severity is the quantification of how serious the condition that caused the failure of a result mentioned in the failure effect. This is a level of seriousness that was written 1,2,3,4,5 (not serious to very serious)
