After rolling out a new update, an organization found a minor bug in its online video game. How should the organization approach this bug while following SRE principles?
A.
Accept and learn from the bug because failure is normal
B.
Accept and ignore the bug because it is only minor
C.
Hold a postmortem to reprimand the employee responsible for the bug
D.
Document bug correction to eliminate all future bugs
Option A is correct. Accepting failure as normal is one of the SRE principles. SREs believe that accepting failure as normal helps to build an iterative, collaborative culture. One
way this is done is by holding a blameless “lessons learned” discussion after an incident occurs.
The primary goals of writing a postmortem are to ensure that the incident is documented, that all contributing root cause(s) are well understood, and, especially, that effective preventive actions are put in place to reduce the likelihood and/or impact of recurrence
Blameless postmortems are a tenet of SRE culture. For a postmortem to be truly blameless, it must focus on identifying the contributing causes of the incident without indicting any individual or team for bad or inappropriate behavior. A blamelessly written postmortem assumes that everyone involved in an incident had good intentions and did the right thing with the information they had. If a culture of finger pointing and shaming individuals or teams for doing the "wrong" thing prevails, people will not bring issues to light for fear of punishment.

A. Accept and learn from the bug because failure is normal
One of the core principles of Site Reliability Engineering (SRE) is that failure is normal. SRE teams understand that things will go wrong, and they focus on building systems that are resilient to failure.
