What should a post-incident lessons-learned session cover?

• A. Root cause, response actions, and improvement commitments.
• B. Only cost impact and downtime duration.
• C. Only immediate containment steps.
• D. Only device inventory changes.

Answer: (A)

A post-incident lessons-learned session should focus on understanding what allowed the incident to happen, how the team responded, and what concrete improvements will be put in place. Delving into root cause means looking beyond immediate symptoms to underlying gaps in processes, technology, or controls so similar events can be prevented in the future. Reviewing response actions helps capture what worked well to contain, mitigate, and recover, as well as any missteps or delays that can be fixed. Establishing improvement commitments turns those insights into action: defining specific changes, owners, timelines, and success metrics for updates to playbooks, controls, training, or procedures. Other options miss the point because they cover only a narrow piece of the picture or focus on outcomes rather than actionable changes. Cost impact and downtime duration are useful metrics but don’t by themselves drive systemic improvement. Immediate containment steps belong to the incident response phase, not the broader lessons-learned review. Device inventory changes are a narrow operational adjustment and don’t address underlying causes or broader process improvements.
