FRACASAnatomy of a failure
If we make an effort and have a plan,
we can capture the information needed for good
failure analysis
Key Takeaway

Today I want to
talk about how the failure
occurs and what data is available for capture.
You work in a small to medium size facility or plant.

You’d like to do good failure analyses when you have an equipment failure but you find you just
don’t have the right information to do it.

by Jorge Franganillo
But you must develop a plan to capture it

and restoration proceeds

Will this give us all the information we need to perform an effective
failure analysis?
Lack of good failure analysis means we’ll continue to loose productivity and profitability because we’ll be fighting same failures over and over.
Develop a plan to capture the right information
With the right information, you can do effective failure analysis
The key to an effective failure analysis is having the right
information
