Toil: coined by Google SRE, it is work like manual deployments, ticket-driven scaling, and handcrafted config changes. Unlike projects, toil is reactive, transient (undone by the next event), and scales with load — not headcount.

Why is reducing toil important for engineering teams?
Toil reduction: SRE teams target keeping toil below 50% of work. High toil crowds out engineering work, causes burnout, and creates a ceiling where the team cannot grow the service without growing headcount proportionally.

What is runbook automation as a toil-reduction strategy?
Runbook automation: if the runbook says "SSH in, restart the service, check logs", automate that into a script or self-healing alert. The human reviews output rather than executing steps, reducing time-to-resolve and errors.

What is a self-healing system in the toil context?
Self-healing: Kubernetes restarts crashed pods; autoscalers add capacity under load; circuit breakers stop cascading failures. Each automated response eliminates a category of pager alerts and manual remediation steps.

How do DORA metrics relate to toil?
DORA + toil: slow deployments often mean manual processes (toil). High MTTR means manual remediation. Automating away toil improves deployment frequency and MTTR — two of the four key DORA performance indicators.
