Defect free execution of a process or product operation is key to efficient working. Defect and product or process severely effect the profitability of operation. It takes 10% to rectify the defect at design stage, while cost to rectify defect at prototype level increases by 100% but this cost goes up by whopping 1000% when defect is identified in the field. Identification and elimination of defect plays a very crucial role in product design or operation for an efficient and effective management of operation. FMEA is a step by step approach of identifying all possible failures in a design, a manufacturing or assembly process, or a product or service that may happen in a workplace. It is a tool to predict what may go wrong with process in future. It is an analytical technique that goes in for combining technology and experience of people o identify foreseen failures in a product or process and planning to eliminate the failure. It eliminates or reduce failures with the highest priority first. FMEA focuses on prevention and helps in improving internal and external customer satisfaction.
