    • The work of reducing toil and scaling up services is the "Engineering" in
    Site Reliability Engineering.
    • Engineering work is novel and intrinsically requires human judgment. It
    produces a permanent improvement in your service, and is guided by a
    strategy. It is frequently creaBve and innovaBve, taking a design-driven
    approach to solving a problem—the more generalized, the beFer.
