You Are Asking the Wrong Questions (about Reliability and SRE)

David Blank-Edelman (Microsoft SRE Academy) explains seven essential questions to elevate your reliability practice. He challenges engineering leaders to redefine reliability metrics beyond availability, replace "root cause" with contributing factors, critique the five whys, re-evaluate the true goals of toil automation, and understand SRE's role (firefighting vs. partnership).
