What Success Looks Like

• Platform stability at scale: The multi-tenant SaaS platform maintains its availability SLO across all tenant tiers as the infrastructure grows from its current state toward a globally distributed commercial release.
• Operational excellence embedded in engineering: Every team shipping to the platform follows a shared production readiness standard, reducing escaped defects and repeated incidents.
• Automated, scalable operations: Tenant onboarding, deployments, and incident remediation are pipeline-driven, eliminating manual toil and enabling the team to scale without growing headcount at the same rate.
• Commercial readiness: The platform meets enterprise securit
