Platform Engineering Maturity Model

November 1, 2021

Platform engineering has emerged as a discipline focused on building internal developer platforms. But maturity varies widely—from ad-hoc scripts to sophisticated self-service platforms. Understanding where you are helps chart a path forward.

Here’s a maturity model for platform engineering.

The Platform Engineering Spectrum

Why Maturity Matters

platform_maturity_impact:
  low_maturity:
    - Developers wait for ops
