Building reliability engineering programs requires not only technological approaches, but also attention to the underlying culture of an organization and how it can help or hinder efforts to enhance reliability. This talk explores how and why cultural values, as part of a broader systems analysis, can help drive reliability. Specifically, this talk presents an anthropologist’s perspective on Meta’s journey from a mantra of “move fast and break things” to one where reliability is increasingly becoming an important value for our engineering community. The audience should take away actionable practices that can be used to evaluate their underlying reliability culture, take data-driven approaches to measuring reliability sentiment, and identify practices that align with existing cultural values and solidify actions to bring reliability to the fore.
