PRODUCTION STANDARD

What “production-ready” means (here)

Production-ready isn’t a date. It’s a system that stays predictable under load, change, and failure—and can be owned without tribal knowledge.

p95/p99 budgetsreversible releasesobservable by default

EXAMPLE BUDGETS

set per project

Availability (SLO)

99.9%

Latency (API p95)

< 200ms

Downtime has a plan

Rollback paths, rate limits, and graceful degradation modes exist before the first release.

Enforced by: release checklist + rollback verification.

Latency is budgeted

p95/p99 targets are explicit, measured at the edges, and treated as a release gate.

Enforced by: budget dashboards + perf regression gates.

Failures are designed for

Timeouts, retries, backpressure, and idempotency are specified—and recovery is tested.

Enforced by: failure-mode review + chaos-style rehearsals (where needed).

Ownership transfers cleanly

Runbooks, decision logs, and operational checklists exist so knowledge is not tribal.

Enforced by: runbook requirement + handoff walkthrough.

THE STANDARDS

Standards we ship by

These aren’t preferences. They’re operating rules that keep delivery fast and systems stable as requirements change.

From definition → standards → gates → artifacts. Each chapter is designed to be reviewable.

Budgets first

Budgets first

Standard: define performance and reliability budgets before feature scope hardens.

Why it matters: budgets keep scope honest and user experience predictable. When teams agree on p95/p99, SLO targets, and cost envelopes early, delivery stays fast—and surprises don’t become late-stage rewrites.

ENGINEERING SIGNALS

  • Critical paths have explicit targets (LCP, p95/p99 latency, throughput, error rates).
  • Measurement is designed upfront: edge instrumentation, load testing plan, and budget dashboards.
  • Performance regressions are treated as release-blocking, not “we’ll optimize later.”

PRODUCTION ARTIFACTS

  • Budget doc: targets + rationale + what “good” looks like
  • Performance measurement plan (where to measure, what to alert on)
  • Dashboards + alert thresholds aligned to user impact
Reversible change

Reversible change

Standard: every change has a safe rollout strategy and a known reversal path.

Why it matters: reversible change turns releases into routine operations instead of high-stakes events. It reduces fear, speeds iteration, and prevents launch-day firefighting from becoming the delivery model.

ENGINEERING SIGNALS

  • Small slices with verification gates (smoke checks, health checks, budget checks).
  • Rollouts are planned (feature flags, canaries, progressive delivery, rollback).
  • Data and API changes are migration-safe: backwards compatible, rehearsed, and observable.

PRODUCTION ARTIFACTS

  • Release plan (rollout steps, verification, rollback triggers)
  • Verification checklist + automated smoke tests
  • Rollback runbook (who does what, how to confirm recovery)
Observable by default

Observable by default

Standard: behavior is instrumented so failures become diagnosable, not mysterious.

Why it matters: observability reduces MTTR and protects velocity. When you can answer “what broke, where, and why” quickly, incidents stop derailing roadmaps.

ENGINEERING SIGNALS

  • Logs carry intent (correlation IDs, key domain events, structured fields).
  • Metrics express budgets (latency, errors, saturation) and are tied to SLOs.
  • Traces show dependency paths so bottlenecks and retries are visible end-to-end.

PRODUCTION ARTIFACTS

  • Signal taxonomy (what we log/measure/trace and why)
  • Dashboards for budgets + drilldowns for incident response
  • Alert-to-runbook mapping so on-call is actionable, not noisy
Explicit contracts

Explicit contracts

Standard: APIs and data boundaries evolve with rules—versioning, deprecation, and compatibility.

Why it matters: contract discipline prevents cascade failures. Clients retry, caches persist, and downstream systems amplify mistakes—so interfaces must be stable, intentional, and safely changeable.

ENGINEERING SIGNALS

  • API semantics are defined (idempotency, retries, timeouts, error taxonomy).
  • Versioning and deprecation windows are explicit—no silent breaks.
  • Schema changes are planned: reversible migrations, backfills, and compatibility strategy.

PRODUCTION ARTIFACTS

  • Versioned API contract + compatibility policy
  • Breaking-change rollout plan (verification + rollback)
  • Data migration plan (staging, rehearsal, observability, recovery)
Secure defaults

Secure defaults

Standard: security is the baseline—least privilege, safe data handling, and auditability.

Why it matters: security retrofits are expensive and disruptive. Secure defaults reduce breach risk, keep compliance achievable, and prevent “ship now, fix later” from becoming permanent debt.

ENGINEERING SIGNALS

  • Least-privilege access across services; permissions are explicit and reviewed.
  • Secrets hygiene is enforced (rotation, storage, and CI/CD controls).
  • Auditability is designed: authentication/authorization events are traceable and reviewable.

PRODUCTION ARTIFACTS

  • Security checklist for build + release (baseline controls)
  • Access boundary map (who/what can access which resources)
  • Incident readiness notes (logging policy, recovery steps, escalation)
Operable handoff

Operable handoff

Standard: we deliver ownership, not dependency—your team can run the system without us.

Why it matters: systems outlive any vendor. Operable handoff prevents vendor lock-in, makes hiring easier, and ensures production behavior doesn’t depend on tribal knowledge.

ENGINEERING SIGNALS

  • Runbooks exist for incidents, releases, and routine maintenance.
  • Decision logs capture the tradeoffs and why constraints exist.
  • Local dev + CI workflows are documented so onboarding isn’t guesswork.

PRODUCTION ARTIFACTS

  • Runbook set (deploy, incident response, recovery verification)
  • Decision log + architecture notes for sustained ownership
  • Operational checklist for release readiness and handoff
