PM SRE Culture
(2026 Edition)
PM SRE culture rests on five concepts — SLOs, error budgets, SLIs, blameless postmortems, and chaos engineering — paired with five PM responsibilities: negotiating SLOs, deciding whether error budget funds features or reliability, prioritising reliability work, driving postmortem action items to completion, and communicating tradeoffs to stakeholders. The SLO conversation is, underneath it, a product prioritisation conversation in disguise.

FAQ
Should PMs care about SLOs?
