What is IDP maturity and what characterises a high-maturity platform?
IDP maturity: the CNCF Platform Engineering maturity model defines levels from "provisional" (reactive, manual) to "optimising" (developer feedback loops, platform metrics, continuous improvement). Higher maturity means developers can provision environments, deploy services, and onboard new tools through self-service without filing tickets to the platform team.

What is a golden path in advanced platform engineering, distinguished from a "paved road"?
Golden path vs paved road: a paved road is infrastructure that's easier to use but still requires decisions. A golden path is opinionated — it answers all choices upfront. Following it delivers production readiness (TLS, auth, metrics, alerts, RBAC) without developer effort. Teams can deviate, but golden path adoption is the success metric for a platform team.

What is a self-service catalog in an IDP and what kinds of resources does it expose?
Self-service catalog: a developer opens the portal, finds the "Postgres database" template, fills in retention and size parameters, clicks "provision," and the IDP triggers a Terraform workflow, wires credentials into Vault, and registers the database in the service catalog — all without a JIRA ticket. This is the core value proposition of an IDP.

What are platform APIs in the context of platform engineering?
Platform APIs: a mature IDP exposes APIs so that CI/CD pipelines, developer CLIs, and IDE plugins can create environments, trigger deployments, and fetch service dependencies programmatically. This moves the platform from a human-operated service to a programmable infrastructure layer that integrates into every developer workflow.

How does a platform team measure the success of an IDP beyond adoption numbers?
IDP success metrics: adoption rates are a leading indicator, not a success metric. A team can adopt a broken platform. Measure: how long does it take a new engineer to deploy their first service? Has DORA Lead Time for Changes improved for golden-path users? Are developer satisfaction survey scores for tooling trending up? The IDP is a product — it needs a product metrics framework.
