Re: No Actual Field Failures (5 years) - Still need Analysis of Potential Field Failu
Welcome to The Cove!
Are you asking if the potential for field failures should not be analyzed for existing product, or for new product?
What is the life cycle of your product? For some products (e.g. computer chips, refrigerators) 5 years without a field failure may not assure a failure will not yet occur.
For new product it should always be done in the
FMEA. Renewed analysis should be done when there are design changes or process changes. The time frame for field failures is generally based on the product's life cycle, safety, customer expectations, and replacement costs.
