Correction of Error document

A Correction of Error (CoE) document should be published by the Service Manager for the service to which it applies. A CoE document should be published whenever a problem occurs - it shouldn't be necessary for the problem to have impacted the users of the service.

The CoE document should contain:

• What the problem was
• What the impact of the problem was
• What the root cause of the problem was
• Data that supports the root cause analysis
• What value tradeoffs were made that led to the problem
• The value tradeoffs that need to be avoided in the future
• Lessons that were learned
• Corrective actions that have been, or will be taken
• Elements of the better decision making guides that made a positive or negative contribution to the problem or its resolution.

The Correction of Error document may then be called upon for further examination during a Correction of Error process.
