In how many ways can a Process FMEA relate with a Lean Six Sigma DMAIC project
DEFINE
Within FMEA, Failure modes can relate to the define the stage of generating a project idea and defining project charter problem statement
Within FMEA, the operation, step, process function (from pfd) can relate to the define stage of creating a high level map
The requirements column informs of the process/customer requirement
Potential Failure mode effect helps define the impact to the customer or producer
MEASURE
Cause segregates the reasons for the failure
Within FMEA, the severity, occurrence, and detection rankings (and raw values) can support the measure effort
Values can help differentiate which measure is more relevant to address
ANALYZE
RPN can relate to the analyze stage to prioritize and down select the project
RPN values can help differentiate which measure is more relevant to address (SO, S, or O, or D)
RPN sets the initial "as is state" of the process to improve from and which causes to mitigate
IMPROVE
Mitigation tasks and assigned personnel and committed due dates relate to improving the target RPNs
Implementation of the change will show if a change (improvement) is realized
Reassessment of change (S<O<D) and the RPN will validate if the change was actually an improvement
CONTROL
Once improvement validated, the living document of FMEA would continue to access if the change is stable
Any change in S, O, or D negative would be reflected in new RPN
