FMEA Tips From the Pros
Facts and Tips About FMECA
Here are some helpful FMEA tips and advice that should prove useful when performing a Failure Mode and Effects Analysis. By having some understanding of the effort involved and some of the timing aspects upfront, you will be better prepared, so that you can plan accordingly. These FMEA tips are listed below so that you can quickly refer to them as necessary.
Helpful Tips and Advice to Aid Your Failure Mode Analysis
The FMEA / FMECA should begin as early as possible
This allows the analyst to affect the design before it is set in stone. If you start early, as recommended, expect to have to redo portions of your analysis as the design is modified.
They take a lot of time to complete
Don't let this scare you and prevent you from performing an FMEA. A product recall can be very costly, time consuming, and cause severe damage to your company's reputation. A FMEA, done properly, can help prevent something like this from occurring.
FMEAs require considerable knowledge of system operation
This is true. FMEAs do require considerable knowledge of system operation, and it will be necessary to have extensive discussions with Software and Hardware Design Engineering, System Engineering, and other disciplines to gather the information that you need.
Spend time developing ground rules with your customer
It is very important to spend time, upfront, developing ground rules with your customer. This will help to prevent misunderstandings in terms of the scope of the analysis, report formats for deliverables, definitions, and other related issues.
Design FMEA Advice
Start early in the process. Complete the Design FMEA by the time preliminary drawings are done, and before any tooling is initiated.
Process FMEA Advice
Start as soon as basic manufacturing methods have been discussed. Be sure and complete the Process FMEA prior to finalizing production plans and releasing for production.
