Suggested conversation arc

  1. 1Choose reliability outcomesIdentify the critical user operations and acceptable degradation, then select a small set of meaningful reliability dimensions.Skills: Prepare task context
  2. 2Define indicators and objectivesSpecify good/total events, data source, window, target, measurement limitations and an initial error-budget policy. Do not assume a perfect target.Skills: Define or review reliability objectives
  3. 3Agree reliability trade-offsReview feasibility with engineering and product, confirm ownership and how budget consumption changes prioritisation or release decisions.
  4. 4Review service evidenceCompare observed performance with the agreement and user experience. Identify blind spots and propose versioned updates rather than silently shifting targets after a breach.Skills: Define or review reliability objectives · Review an artifact against agreed criteria

Output

SLO definition: user expectations, SLI definitions, objectives with window and owner, and the error-budget decision policy.

What good looks like

  • Indicators have unambiguous measurement definitions.
  • Targets and policy approval are distinguishable from suggestions.
  • No measured attainment claim without telemetry; no alerts configured or production changed.

Quality gate

The service owner confirms targets, ownership and the error-budget policy with engineering and product.
