A DFMEA (Design Failure Mode and Effects Analysis) is a systematic approach to identifying potential failure modes in a product or process and their associated effects. It is a proactive tool used to identify potential problems before they occur and can be used to improve product reliability and reduce the risk of failure. A DFMEA example would be a manufacturer of a car engine looking at all the potential failure modes and their effects. This could include examining the components of the engine, the assembly process, and the environment in which the engine will be used. The DFMEA would then identify the potential failure modes and their associated effects, such as engine noise, vibration, and poor fuel economy. The DFMEA would then look at the severity of the effect, the likelihood of the failure mode occurring, and the detectability of the failure mode. By doing this, the manufacturer can prioritize the potential failure modes and develop solutions to reduce the risk of failure.
