I am planning to conduct FMEA study for some of the existing equipment/device.This device has several models, most of them have almost same design features. I wish to find out the weak parts/sub component of these device type by conducting the study.
Since number of different models of this device are available in the market, it is not possible to conduct study on all the models.
Whether it would be appropriate to conduct FMEA study on specific model and conclude the results for the whole species of the devices?
FMEA application can be extended if the basic devices/equipments have very similar characteristics in terms of materials, component parts (i.e. mechanical or electrical components), working principle.
FMEA is a general model for hazard identification and risk assessment. this method is be able to work any product species.
As long as the different models are similar in functions, it is more efficient to maintain a single FMEA to cover them. Within the single FMEA, it is possible to denote some failure modes as specific only to Model X. Or you could add an extra column to input which are the applicable equipment for each line item.
Thanks everybody
@Brian, I think its a nice idea to add extra column for additional design features.
FMEA sections on like for like components can with care and consideration be copied efficiently and thus often do not need to be analyzed for each model - over and again. Specific to each model, are only the differences, and these when incrementally examined allow you to cover many models of similar construction with a common FMEA that then includes the portions that are specific to each model.
