Questions this course answers

What makes a post-incident review a lessons-learned review rather than a blame exercise?

Learning focuses on how the system behaved and what can be changed, while blame does not explain the control or decision path.

Put the core review steps in a defensible order.

A reliable review starts with preserved evidence and scope, then explains causes and impact before assigning changes.

Match each control claim to the evidence that would test it.

A claim becomes a lesson when the control is tested in the same path, scope, and operating condition that mattered in the incident.

In your own words, why should a customs-business impact analysis remain separate from a technical root-cause analysis?

Separating the tracks prevents an unresolved cause from hiding a known operational effect, and prevents a known effect from being exaggerated into a technical conclusion that evidence does not support.

What shows that a lesson has entered normal operations?

Closure is durable only when the change can be checked and a future signal can reopen the issue if its assumptions fail.
