The answer depends on whether an assignable cause can be identified. In the majority of cases, an assignable cause does not exist. In this case, the nonconformity should be evaluated to determine whether the current risk controls are within an acceptable risk tolerance (established by the company). If not, then there may be additional risk controls that can be put into place to mitigate the risk to an acceptable risk tolerance. | The answer depends on whether an assignable cause can be identified.

One of the most common failed attempts at error proofing we see appears in documents, e-mails & text messages. Of course, I'm speaking of the auto-spell correction. These have resulted in some hilarious memes. These are much better described as "risk mitigation" | One of the most common failed attempts at error proofing we see appears in documents, e-mails & text messages.
