FMEA (Failure Mode and Effects Analysis) is about make a prediction…
It is a systematic approach to:
- recognize the potential failure of product or process and the effect of the failure
- identify actions that could eliminate or reduce the chance of potential failure occurring
The differences between FMEA and FMA or FA:
- FMEA – the failure is not yet happened. FMA/ FA the failure is happened already.
- FMEA – work on forecasted failure, the causes and its effects/ impacts. FMA/FA – work on known trouble units.
Types of FMEA:
- Design FMEA (d-FMEA) or Product FMEA.
The focus is on the product itself, such as: components, raw materials, feature, or characteristics. - Process FMEA (p-FMEA) or Manufacturing FMEA or Production FMEA.
The focus is on manufacturing process, such as: Process flow, Equipment, Tooling, Operators. - System FMEA (SFMEA).
Focus on potential failures associated with the functions performed at the system, subsystem and lower functional levels. It is also about the interaction between systems, subsystems, and the interface between system elements. - Service FMEA (s-FMEA)
Focus on field service after sales
or
Focus on Instruction and Warning label
or
Focus on reliability, maintainability, spare part availability and other field service related activities - Application FMEA (a-FMEA)
- On supplier side, focus on supplier design as well as manufacturing process to maintain the key/significant characteristic of the products.
- On customer side, focus on customer manufacturing process, with prime interest is on compatibility between your products and your customer’s process
or
your process with your customer’s process.
That’s it for now… will be continued latter.
