FMEA is know as Failure Mode and Effect Analysis. It can be divided into two major part, the process and design FMEA. is one of the first systematic techniques for failure analysis. It was developed solidly to study problems that might arise from malfunctions of military systems. It is a structured approach to discovering potential failures that may exist within the design of a product or process.
Failure modes are the ways in which a process can fail. Effects are the ways that these failures can lead to waste, defects or harmful outcomes for the customer. Failure Mode and Effects Analysis is designed to identify, prioritize and limit these failure modes.
FMEA enhances good engineering by applying the knowledge and experience of a Cross Functional Team (CFT) to review the design progress of a product or process by assessing its risk of failure. We can used FMEA to quantify the risk and calculate the long term and short term risk, thus can confidently prevent the risk in future.
There are two broad categories of FMEA, Design FMEA (DFMEA) and Process FMEA (PFMEA). These FMEA normally used in almost all the manufacturing factories in the world.
Historically, the sooner a failure is discovered, the less it will cost. If a failure is discovered late in product development or launch, the impact is exponentially more devastating.
FMEA is one of many tools used to discover failure at its earliest possible point in product or process design. Discovering a failure early in Product Development (PD) using FMEA provides numerous benefits in term of manpower, cost, engineering and quality.
