Basics of Incident investigation
Incidents do happen. But we should not let them repeat. Learn
from your mistakes, work out a solution and be sure that the incident is not
repeated. This is the main reason why we investigate incidents.

The incident investigation should concentrate on finding
answers to the three questions
- What happened?
- Why did it happen?
- How to prevent repetition?
The organization should have an effective system to track
the implementation of corrective action which should be based upon the
principle of Verify and Validate. If the system has loop holes even after the corrective
action has been implemented, the condition should be reviewed and a better
corrective action will be put forward which will again go through the Verify
and Validate stages until satisfactory results are achieved.
Every incident investigation should hence find out at least
one Root cause, and a set of contributing causes.
