Measure reliability, then actually improve it.

Not at all. The smaller your team, the more you get out of SLOs and runbooks, because every page costs you more when there are only three engineers to absorb it. We size the practice to fit your team.

Done right, it does the opposite. An error budget gives engineering clear permission to ship fast while reliability is healthy. The brakes only come on when you're burning through the budget faster than it refills.

We can, through a managed SRE retainer with agreed SLAs. Most clients would rather we set up the practice, train their team, and then hand the pager over. Either arrangement works.

An SLI is the measurement, such as the percentage of requests served under 300ms. An SLO is the target you hold that measurement to, such as 99.9% of requests. An SLA is the contractual promise to a customer, usually set looser than your internal SLO so you have headroom.

We start from real user journeys and historical data rather than an aspirational round number. The target should reflect what your business genuinely needs and what your architecture can sustainably deliver, because every extra nine costs real engineering effort.

An error budget is the amount of unreliability your SLO allows, for example the 0.1% of downtime left by a 99.9% target. While budget remains, engineering ships fast. When it runs low, the agreed policy shifts focus to reliability work until the budget recovers.

We alert on symptoms your users feel, such as failing checkouts, rather than every CPU spike, and we tie thresholds to your SLOs. Noisy and duplicate alerts get pruned, so the on-call engineer trusts the pager again and stops ignoring a channel full of noise.

We design rotations wide enough that no two people carry the whole load, with clear page-routing and escalation rules. Pages outside business hours are reserved for things that genuinely cannot wait, and runbooks mean the on-call person follows a tested checklist instead of debugging cold.

Clear severity levels, a named incident commander, a scribe, and a comms role, plus communication templates and a status page workflow. When the page fires everyone knows their job, so the time goes into fixing the problem rather than figuring out who does what.

Blameless postmortems turn each incident into a tracked fix, and we review patterns across incidents to find the recurring root causes. Closing those action items, rather than filing reports, is what stops the same outage from coming back and steadily raises uptime.
