As shown in practice, every error that can theoretically happen will eventually occur and repeat itself if nothing has been done to counteract the causes of the error. Therefore, it is constructive to determine error causes systematically and to remedy them vigorously.
Damage undoubtedly constitutes an annoying event. Therefore, any failure or damage, accompanied by a systematic damage analysis, should be taken as an opportunity to achieve meaningful and targeted improvements.
The frequently practised methods of trying to prevent future failure through snapshots or time-consuming trial and error operations often lead to misdirected, incorrect, delayed, excessive and therefore expensive measures. A systematic failure analysis on the other hand can provide valuable information about component properties that are of central importance to a product's service life and need to be improved to prevent a recurrence of the issue. A systematic failure analysis can help avoid inappropriate, impracticable or excessive measures.
