Tiered Customer Experience SLOs

Premium customers get tighter SLOs.

Tiered SLO model

Different commitment levels per customer tier. Premium tier: tighter SLOs, dedicated capacity. Standard tier: standard SLOs. Basic tier: best-effort.

Encodes the commercial trade-off in operational policy. Customers paying more get more reliability, with concrete commitments backing it.

Differentiates against competitors who offer the same product without tiered reliability.

Three tiers usually sufficient: premium, standard, free. More tiers create operational sprawl.

Per-tier SLOs explicit: 99.95% / 99.9% / 99% availability typical. Latency targets similarly differ.

Per-tier capacity: dedicated capacity for premium; shared for standard; oversubscribed for free.

Per-tier monitoring and alerts. Premium SLO breach pages immediately; standard breach goes through normal triage.

Per-tier on-call response. Premium incidents may have dedicated escalation paths.

Customer-facing per-tier reporting. Each customer sees their own tier's performance over time.

Premium tier promises must be backed by engineering capacity. Without dedicated investment, premium becomes a broken promise.

Capacity headroom, redundancy, and operational priority match the SLO. Premium customers may have separate clusters or routing.

Annual review: tier delivery versus pricing. Adjust pricing or engineering investment to match.

Public SLO commitments per tier. Concrete numbers in pricing pages and contracts.

Track and report achievement. Premium customers receive monthly or quarterly reports verifying their tier's performance.

Sales enablement uses concrete numbers. 'We hit premium tier targets in 11 of 12 months last year.'
