What is FMEA ?
The
idea that the FMEA proposes is not revolutionary; it is a
simple yet systematic methodology used to approach problems,
concerns, challenges, errors, and failures, to seek answers
for improvement.
FMEA
is a specific methodology to evaluate a system (SFMEA), design
(DFMEA), process (PFMEA), or service for possible ways in
which failures (problems, errors, risks, concerns) can occur.
For
each of the failures identified (whether known or potential),
an estimate is made of its occurrence, severity, and
detection. At that point an evaluation is made of the
necessary actions to be taken, planned, or ignored. The
emphasis is to minimise the probability of failure or to
minimise the effect of failure.
Introduced
by the major car manufacturers (Chrysler 1986, General Motors
1988, Ford 1992) - used in their supplier certification
standards requiring FMEA programs for their suppliers.
Also
used in other industries such as semiconductors, computer,
government, and medical device.
Through
product liability, courts may also require some substantiation
as to what level of reliability products and / or services
perform.
