10 Steps to do a FMEA Process

Step	Short Description	Short Description
Step-1	Review the Process	1. Review the All Risk for Desire Area 2. Identify the Risk of Process Component 3. Drow the Process Compnent on table 4. Dicuss the basic Fratures, assembly, material,construction and Desire function.
Step-2	Brainstorm of Potential Failure	1. What Could go Wrong ? 2. Review of Existing Documentation 3. Consider the Potential failure modes for each component and its corresponding function . 4. Using the list of component and releted function of step-1 (Review the process). 5. As a expert , Brainstrom the potiential failure modes for each and Every function not missing, 6. Risk findout every mode and current Control.
Step-3	List of Potiential Effects of each failure mode	1. What could happen if this failure occure ? 2. Consider the possible failures and imagine what could then happen to the surrou.nding environment and people. 3.There will likely be more than one effect for each failure
Step-4	Assign a severity ranking for Each Effect	1. Assign a severity ranking to each effect that has been identified. 2. The severity ranking is an estimate of how serious an effect would be should it occur. 3.To determine the severity, consider the impact the effect would have on the customer, on downstream operations process, or on the employees operating the process. and Control of the product. 4. The severity ranking is based on a relative scale ranging from 1 to 10. i.e Ranking  1 means Severiy is Low and Rank 10 means effect is very dengers without Warning.
Step-5	Assign an occurrence ranking for each failure mode	1. Occurrence rankings are based on how frequently the cause of the failure is likely to occur. 2. consider the potential cause or failure mechanism for each failure mode; then assign an occurrence ranking to each of those causes or failure mechanisms.
Step-6	Assign a Dection Ranking for Each failure mode /or Effect	1. What are the chances the failure will be detected prior to it occuring. 2. Based on the chances the failure will be detected prior to the customer finding it. 3. A control can relate to the failure mode itself, the cause or mechanism of failure, or the effects of a failure mode. 4. To make evaluating controls even more complex, controls can either prevent a failure mode or cause from occurring or detect a failure mode, cause of failure, or effect of failure after it has occurred. 5.  The Detection ranking scale, like the Severity and Occurrence scales, is on a relative scale from 1 to 10. 6. A Detection ranking of “1” means the chance of detecting a failure is certain. 7. “10” means there is absolute certainty of non-detection. This basically means that there are no controls in place to prevent or detect
Step-7	Calculate the risk priority number for each effect	1. RPN = Severity X Occurrence X Detection. 2. The RPN is the Risk Priority Number. The RPN gives us a relative risk ranking. The higher the RPN, the higher the potential risk. 3. The RPN is calculated by multiplying the three rankings together. Multiply the Severity ranking times the Occurrence ranking times the Detection ranking. Calculate the RPN for each failure mode and effect.
Step-8	Prioritize the Failure modes for Action./Develop the Action plan .	1.Decide which failures will be worked on based on the Risk Priority Numbers.  Focus on the highest RPNs. 2. The RPN can be reduced by the three rankings (severity, occurrence, or detection) individually or in combination with one another. 3. A reduction in the Severity ranking for a PFMEA is often the most difficult. It usually requires a physical modification to the process equipment or layout. 4. Reduction in the Occurrence ranking is accomplished by removing or controlling the potential causes. 5. Define who will do what by when.
Step-9	Take Action to reduce the high risk failure mode	1. Implement the improvements identified by your Process Failure Mode and Effects Analysis team . 2. Most Action Plans identified during a FMEA will be of the simple “who, what, & when” category. Responsibilities and target completion dates for specific actions to be taken are identified . 3. the Action Plans can trigger a fairly large-scale project. If that happens, conventional project management tools such as PERT Charts and Gantt Charts will be needed to keep the Action Plan on track.
Step-10	Calculate the resulting RPN As per Failure mode are redused./ Calculat the resulting RPN.	1. Re-evaluate each of the potential failures once improvements have been made and determine the impact of the improvements. 2. This step in a PFMEA confirms the action plan had the desired results by calculating the resulting RPN. 3. To recalculate the RPN, revaluation the severity, occurrence, and detection rankings for the failure modes after the action plan has been completed
