Failure Mode Explorer

How should we investigate this failure?

Turn an observed symptom or product risk into a clearer investigation starting point. About 3 minutes. Result: An investigation problem statement.

Your project brief

Save a useful result from any tool; you do not need to complete them all

Open project brief

Start with what you can observe

Cracking, loosening, or intermittent functionSeal, fit, or performance changes with temperatureLeak, pressure loss, or unstable flowCoating, surface, or material condition changes

When does it appear?Another exposure that may be involved

Possible exposure path

Mechanical input, resonance, shock, or repeated movement

Questions that improve the investigation

01When did the behavior first appear?
02Is the condition repeatable at a known operating point?
03What mounting condition was used when it occurred?

Evidence on hand

What can you bring to the first review?

Photos or visual observationsMeasured data or logsReturned or failed sampleKnown reproduction condition

Investigation starting point

Discuss mechanical input, resonance, shock, or repeated movement in the context of “cracking, loosening, or intermittent function.”
