Designing FMEA

To set up FMEA data:
1. On the FMEA Classifications form, specify all possible failure classifications.
2. On the FMEA Failure Modes form, specify all possible failure modes.
3. On the FMEA Ratings form, accept the default ratings standard or specify your own.
  
  Note: The default entry "No effect unlikely" represents the lowest possible severity rating.
Open the FMEA Maintenance form.
In the header, specify the item, operation, and work center.
In the Causes and Controls section, specify the type of failure, its potential causes, and other factors. When you specify the Classification, its description displays in the Potential Causes field.
Select ratings in the Severity, Occurrence, and Detection fields. These fields are used to calculate the RPN field, using the following formula: Severity * Occurrence * Detection.
In the Action Information section, specify how to respond to the potential failure, as well as what steps have already been taken and how they affected the RPN.
Select ratings in the Action Severity, Action Occurrence, and Action Detection fields. These fields are used to calculate the Action RPN, which represents the effect your actions had on the original RPN.
