Your CTO has asked you to implement a postmortem policy on every incident for internal use. You want to define what a good postmortem is to ensure that the policy is successful at your company. What should you do? (Choose two.)

Answer options

• A. Ensure that all postmortems include what caused the incident, identify the person or team responsible for causing the incident, and how to prevent a future occurrence of the incident.
• B. Ensure that all postmortems include what caused the incident, how the incident could have been worse, and how to prevent a future occurrence of the incident.
• C. Ensure that all postmortems include the severity of the incident, how to prevent a future occurrence of the incident, and what caused the incident without naming internal system components.
• D. Ensure that all postmortems include how the incident was resolved and what caused the incident without naming customer information.
• E. Ensure that all postmortems include all incident participants in postmortem authoring and share postmortems as widely as possible.

Correct answer: C, E

Explanation

Option C is correct because it emphasizes the need to understand the incident's severity and preventive measures while avoiding mentioning internal components, which helps maintain operational security. Option E is also correct as it promotes inclusivity by involving all participants in the postmortem process and encourages widespread sharing, which enhances transparency and learning. The other options either focus too much on individual blame or include unnecessary details that do not align with best practices for effective postmortems.
