SLO & error budgets
Product-led SLOs your CEO understands. Error budgets that govern release cadence and feature freezes - in writing.
SLO · SLI · burn rateCloud & DevOps - 04 of 04
Reliability as a number. Not a hope.
SLOs your product team helped write, error budgets that govern release speed, on-call rotations engineers do not resent. We either run SRE for you, or stand up your team and train them - the goal is a system that stays reliable after we leave.

What you get
SRE as a discipline, not a job title.
Six muscles every reliable system needs - whether you have an SRE team yet or not.
Observability
Metrics, logs and traces from one OTel pipeline. Dashboards that actually answer the on-call next question.
OTel · traces · USE / REDIncident management
Severity model, comms rituals, IC role, paging policy. Pages route to the right human - not the whole channel.
IC · paging · commsRunbooks & toil reduction
Every alert links to a runbook. Every runbook has a "why is this not automated yet" field. Toil tracked, capped, retired.
runbook · toil · automationOn-call & culture
Humane rotations, comp policy, follow-the-sun where it fits. Blameless postmortems that read like engineering documents.
humane on-call · blamelessChaos & resilience
Game days, fault injection, DR drills, dependency "what-if" mapping. Resilience proven on a Tuesday - not discovered on a Friday.
chaos · game-day · DR drillHow it works
A flywheel: observe, respond, learn, automate.
SRE is not a project plan; it is a loop that improves every cycle. We help you turn that loop - then keep it turning.
SLOs are the contract. Everything else flows from them.
Start by writing what reliable means - product can sign it, engineering can measure it. From there, the rest of the practice has a job to do.
- 01
Pick SLIs people care about
Latency, success-rate, freshness. The number a customer notices, not a CPU graph.
- 02
Write SLOs with product
What good enough means, in numbers. Signed by both sides - not negotiated mid-incident.
- 03
Govern releases by budget
Budget healthy -> ship fast. Budget breached -> freeze, fix, then ship again. Policy, not vibes.
- 04
Retire toil quarterly
Every quarter, kill the top three toil items. The practice gets cheaper, not more expensive.

From vision to victory
From hope to a number, in eight weeks.
First SLOs live in week three. First chaos drill in week six. Steady operating rhythm by week eight.
01
Week 1-2SLI / SLO discovery
Pick the SLIs that map to customer pain. Draft SLOs with product - not unilateral engineering numbers.
02
Week 3Instrumentation
OTel everywhere. SLOs computed from real signal, dashboards stood up, alerting tuned to budget burn.
03
Week 4-5Incident discipline
IC role, severity, comms template, runbooks. Practice with a tabletop before a real Sev-1.
04
Week 6Chaos & DR drill
Fault injection on a non-customer-impacting day. Validate runbooks, find the gaps.
05
OngoingOperate or hand off
We run on-call alongside you, or hand the practice off with quarterly reviews.
Where it lands
Three SRE programs that stuck.
Reliability that survived the next quarter, the next leader, the next surprise.
From 90-minute pages to 14.
Build-your-own SRE practice for a 200-engineer SaaS. SLO contracts with product, runbook discipline, OTel-first observability.
