Meaning
• It is a preventive measure to systematically display the causes, effects and possible actions regarding observed failures.

FMEA an engineering technique use to define, Identify and Eliminate known and / or potential failures, problems, erors which occur in the stystem, design, process and service “before they reach the customer”.

FMEA is “before-the-event” action and is done when existing system/products/processes are changed or redesigned

objective
• The objective of FMEA is to anticipate failures and prevent them from occurring. FMEA prioritizes failures and attempts to eliminate their causes

Types
• 1.System FMEA:• Analyzes components, subsystem and main system in early stage of design. • 2.Design FMEA:• Analyzes the products/parts before they are released to manufacturing.

• 3.Process FMEA:• Focuses on manufacturing and assembly processes. • 4.Service FMEA:• Analyzes services industry proceses before they are released to impact the customer. And Equipment,Maintenance, Concept FMEA,

Types
5.Environmental FMEA
• However, in practice, all the above types can be broadly categorised into two types….. • 1.Design FMEA involves the analysis of the potential failures of product or service due to component or subsystem unreliablility. • 2.Process FMEA -Manufacturing process-The Process FMEA is used primarily to identify areas of critically of control and to emphasize the design and more reliable process – It may be noted the equipment,service, and environmental FMEA are slightly modified versions of process FMEA
