Define FMEA Controls

Explanation

This activity is used to enter information about one or more controls associated with each cause of a failure. Controls are activities that may assist in the identification, prevention and/or detection of design or process failures or their effects.

To enter detailed information about a control for a FMEA failure cause, first open the Design FMEA or Process FMEA page, expand the record for the corresponding part in the record selector by clicking Expand, open the appropriate level and select the specific failure cause. Alternatively open the FMEA Failure Causes Details page and select the record for the corresponding failure cause in the record selector. Then, click the new command on the Controls tab, enter information about the control, including detection, and click Save.

Detection is an assessment of the ability of the proposed control. Each control has a detection ranking. Each cause has one or many defined control(s). These control(s) will be evaluated as a group for each cause when assessing the detection ranking used for risk priority number (RPN) calculation. Therefore, the most efficient control takes precedence when calculating the RPN number. This means that the lowest detection ranking will be used for the RPN calculation.

Prerequisites

This activity requires the existence of at least one structure or routing alternate. This alternate must be associated with at least one FMEA function, failure and cause.

System Effects

As a result of this activity, you will have entered information about one or more FMEA control,, that are related to the cause of a failure. You will also have entered the detection ranking for each control.
