Key Terms
Typically abbreviated FMEA, this is a structured methodology for identifying and assessing risks associated with a design or process.
What is Failure Modes and Effects Analysis?
A Process FMEA should be started during this phase of the Mueller NPD process.
What is Phase 4?
Usually known by its abbreviation, this rank gives you a relative risk score for each line item in your FMEA.
What is Risk Priority Number?
The FMEA concept was formalized by this group.
What is the U.S. Military?
This type of FMEA assumes everything is built correctly (i.e. no nonconformances).
What is Design?
This document is a critical input into the design verification and validation test plan.
What is a DFMEA?
This value represents the impact of the failure mode.
What is Severity?
FMEAs were first used in the US in this decade.
What is the 1940s?
Although the same term is used in both FMEA types, in a process FMEA it represents the process step and in a design FMEA is represents the system, sub-system, or component.
What is Item?
The Process FMEA is used as an input to this document, which is often owned by Quality.
What is a Control Plan?
Controls Prevention is an input into this ranking.
What is Occurrence?
This group, coming out of the automotive industry, was established to begin standardizing FMEAs.
What is AIAG?
Examples of these in a design FMEA might be validation testing or the use of design standards; in a process FMEA, you're more likely to see "QA inspection".
What are Controls?
A FMEA can be considered as this when there is no new information and current risk levels are acceptable.
What is "stable"?
This ranking tells you how likely you are to find a failure after it has occurred.
What is Detection?
AIAG published the first official FMEA standard in this year.
What is 1993?
This term describes the way in which a process step or product can fail to meet its function.
What is Failure Mode?
Used as an input for both the Design FMEA and the baseline design, these are typically documented at Mueller in a Market Requirements Document (MRD).
What are User Needs?
This equation gives you your total risk score, or RPN, for each line item.
What is Severity x Occurrence x Detection?
The FMEA concept was first documented in this military standard.
What is MIL-P-1629?
