FMEA (failure mode and effect analysis):

It is an engineering technique which is used to define, identify, eliminate, problems and potential failures. Failure mode and effect analysis is a continuous process to anticipate and prevent them from occurring priorities and attempts to eliminate their causes. The objective of FMEA is to analysis components, sub system and main system in early stage of design. It consists of eight type of EFMA
• Concept FEMA.
• Service FEMA.
• System FEMA.
• Environment FEMA.
• Design FEMA.
• Process FEMA.
• Maintenance FEMA.
• Equipment FEMA.
In the design process the analysis of the potential failures of product of service due to component of subsystem unreliability. It involves a failure analysis of a manufacturing process and it is used for preliminary to identify areas of critically of control and to emphasize the design and more reliable. FEMA is the team effort and needed to prepare FEMA product and process specifications, reliability data, customer priority data, process description and inspection data. The team should have assembly engineer, materials engineer, service engineer, suppliers, manufacturing engineer and the customer. FEMA is the product to perform as expected for a certain period of time under the given operating conditions.
