Answer: Focus on identifying the contributing causes of the incident rather than the individual responsible for the cause.
In Site Reliability Engineering (SRE) practices, post-mortems prioritize a blameless culture to foster learning and prevent future incidents. The focus should be on systemic issues and contributing factors rather than individual fault. Option B aligns with this by emphasizing identifying contributing causes (e.g., insufficient testing, resource monitoring gaps, or deployment processes) without targeting individuals. Option A contradicts SRE principles, as avoiding recurrence is critical. Option C and D promote blame by investigating individuals or punishing engineers, undermining trust and hindering transparency. SRE encourages collective responsibility and process improvements.

A
Focus on developing new features rather than avoiding the outages from recurring.
B
Focus on identifying the contributing causes of the incident rather than the individual responsible for the cause.
C
Plan individual meetings with all the engineers involved. Determine who approved and pushed the new release to production.
