Root Cause |
|
After the problem/event
is contained, the causes must be identified to prevent recurrence.
The direct cause is the source that directly results in the nonconformance. Contributing causes
are those that left unchecked, bring about the direct cause but on their own, may not have sufficient power to result in the event taking place.
Root Cause is simply the last logical cause in the chain and the fundamental
systematic change necessary to prevent a recurrence. Tools to
assist in identifying causes include the
5 Whys
or a
Fishbone Diagram.
