CTO Playbook — Steady State

Steady state is the equilibrium where engineering teams ship predictably, incidents stay rare, and calendar space remains for architecture work. This playbook spells out eight principles a modern CTO has to operationalize in 2026 — architecture decisions, CI/CD maturity, DORA metrics, tech-debt management, EU-AI-Act-compliant governance, and agentic-layer integration. Plus two deep dives: CI/CD and testing as one coupled discipline, and how the CTO role shifts with company size (solo-founder → Series C). For VPs of Engineering, CTOs in growth or consolidation phases, and engineering leads aiming for that next step. Concrete, applicable, hype-free.
