Benefits of FMEA

FMEA is designed to assist the engineer improve the quality and reliability of design. Properly used the FMEA provides the engineer several benefits. Among others, these benefits include:

* Improve product/process reliability and quality
* Increase customer satisfaction
* Early identification and elimination of potential product/process failure modes
* Prioritize product/process deficiencies
* Capture engineering/organization knowledge
* Emphasizes problem prevention
* Documents risk and actions taken to reduce risk
* Provide focus for improved testing and development
* Minimizes late changes and associated cost
* Catalyst for teamwork and idea exchange between functions

Use of FMEA

Historically, the engineers have done a good work of evaluating the functions and the form of products and of processes in the phase of the design. They have not always done so well in designing in reliability and quality.

The engineer uses safety factors as way of making sure that the design will work and it protected often user against product or absence in the process.According to the described in a recent article:

"a great factor of safety does not translate necessarily to a reliable product. In place, it often leads to redesigned the product with problems of the trustworthiness."

FMEA provides to the engineer a tool that can attend the reliable supplying, safe, the pleasant products and the processes of the client.

Since the FMEA aid the engineer identifies the potential product or lack of process, they can use it:
* They develop the product or the process requisites that limit to the minimum the probability of these absences.
* Evaluate the obtained requisites of the client or of other participants in the process of the design to make sure that these requisites do not introduce potential absences.
* They identify the characteristics of the design that they contribute to the absences and design them out of the system or limit to the minimum at least the effects that prove.
* They develop the methods and the procedures to develop and to prove the product / process to make sure that the absences have been eliminated successfully.
* He continues and handles the potential risks in the design. To continue the risks contributes to the development of the corporate memory and of the success of the future products also.
* Make sure that any absence that might happen should not damage or affects seriously client of the product / process.

Types of FMEA

There are several types of FMEA, something is used much more often that others. FMEA must be always done whenever the lack meant damage or potential injury to the user of the article of the end that is designed.

The types of FMEA are:
* System - centers in global functions of the system
* Design - centers in components and subsystems
* Process - centers in processes of the manufacture and assemblies
* Service - centers in functions of the service
* Software - centers in functions of software

Failure Mode and Effect Analysis (FMEA)

The clients are bringing increasing suits in the companies for the high quality, reliable products. The capacities and the functionality of increase of many products are making more difficult so that the manufacturers maintain the quality and the trustworthiness. Traditionally, the trustworthiness has been reached with the extensive test and the use of techniques such as to model probabilistic of the trustworthiness. These technical are done in the last stages of the development. The challenge is to design in quality and early trustworthiness in the development cycle. The analysis of the ways and the effects of failure (FMEA) is methodology to analyze potential problems of the early trustworthiness in the development cycle where it is easier to take actions to surpass these editions, of such way heightening trustworthiness with design. FMEA is used to identify potential ways of failure, to determine their effect on the operation of the product, and to identify actions to attenuate the lack. A crucial step is anticipating what could go badly with a product. Whereas to anticipate each way of failure it is not possible, the equipment of the development must formulate so extensive a list of the potential ways of failure as it is possible. The early and constant use of FMEA in the process of the design allows that the engineer designs outside lack and produces reliable, safe pleasant products, and of the client. FMEA also captures the historical information for the use in the future improvement of the product.
