The Challenge

Engineering was spending roughly a third of its time on unplanned incident response. There were no SLOs, alerting was noisy enough that engineers muted it, and postmortems happened inconsistently with no follow-through on action items.

Engineering Approach

[01]
Defined SLIs and SLOs for the five most business-critical user journeys.
[02]
Rebuilt the observability stack around distributed tracing and consolidated dashboards.
[03]
Re-tuned alerting to page only on symptoms that mattered, cutting alert volume by 70%.
[04]
Introduced a blameless postmortem process with tracked, owned action items.

Business Results

P1 incidents dropped 68% within the first quarter post-engagement.
Mean time to resolution improved 5x with better observability and runbooks.
On-call engineers report fewer 3am pages and a genuinely better quality of life.
Reliability work now has a standing budget instead of competing with features by default.
