1. Record product or process functions. The purpose of this step is to outline how a product or process works in the order in which functions are performed.
2. Determine under what circumstances these functions will fail (failure mode).
3. Determine the importance of failure results; In steps 2 and 3, the team should carefully consider negative opinions and test which part of the product or process is most likely to fail, how the failure occurs, and the severity of the consequences of the failure.
4. Confirm the reason and probability of failure, and don't focus too much on those rare failures.
5. List the existing methods of fault detection and prevention and the possibility that these methods are effective. In this step, it is necessary to set an awareness level for products and processes before the team evaluates and prioritizes the risks involved.
6. Assess the risk of each failure.
7, determine the appropriate action to deal with the highest risk of failure, this is the most important step. In this step, we can take appropriate measures to reduce or eliminate the potential failures found before. Without this step, all other steps will be useless.
