FMEA Audits (Sufficiency Reviews)
PlanTech has developed an audit methodology to review existing FMEAs for sufficiency, ensuring they meet quality objectives. Our experts will
review your documentation prior to submitting to your customer ensuring all requirements are met.
The sufficiency review consists of two parts:
Part A |
Part B |
PlanTech will review your FMEA and provide general and specific observations of problem areas. |
PlanTech will complete a 29 point checklist built on the Ten FMEA Quality Objectives found in the AIAG and SAE Reference Manuals. |
OEM Specific Requirements for FMEA
Generally, companies follow the requirements set out by the Automotive Industry Action Group (AIAG) or Society of Automotive Engineers (SAE).
However each of the OEMs in Detroit has their specific requirements for FMEA. PlanTech has worked with the Detroit OEMs for over ten years and
understand their specific requirements.
GM - DRBFM
DRBFM is used to examine product designs ensuring the areas most susceptible to change are properly reviewed. If we have a stable,
proven, good design and do not change the design, the risk of failure or encountering problems is low. Therefore, the basis for
reliability is to not change the design.

Problems occur where changes are made and to those areas in the design that are discontinuous. Discontinuity exists at the interfaces
of components or subsystems and when design changes are made.
If the design is changed, it should be done in small increments. The disturbance to a design is the discontinuity caused by a design
change affecting the interfaces between parts.
Ford - The Parameter Diagram (P-Diagram)
A P-Diagram (Parameter Diagram) is a tool used to identify inputs and outputs for a design under analysis. Once specific inputs and
outputs have been identified, error states are identified. Noise factors, outside the control of the design engineer that could lead
to error states are then listed.
The five Noise factors are:
- Piece-to-piece variation
- Changes over time (wear)
- Customer usage
- External Environment
- System interactions
Control Factors are then applied as a means to control the noise.
Chrysler - Function Models
A function model is a diagram that shows the relationship between the goal of performing a function and the means by which it is
satisfied in a design. It defines a function as a task which a design is intended to perform. It then describes how the various
sub-elements of a design are responsible for satisfying the function.
