What do DORA metrics measure in the context of platform engineering?
DORA (DevOps Research and Assessment) metrics are the industry-standard way to measure software delivery performance. Platform teams use them to demonstrate the impact of their work: a well-designed golden path typically improves Deployment Frequency and Lead Time for Changes while reducing Change Failure Rate. Teams are classified as Elite, High, Medium, or Low performers based on these metrics.

A platform team says they are 'at level 2 of the platform maturity model.' What does this indicate?
Platform maturity models (such as those from Gartner or the CNCF Platforms whitepaper) typically describe a progression from reactive/ad-hoc tooling to a product-managed internal platform with clear SLOs, a roadmap, and measurable DevEx impact. Level 2 usually means the platform exists as a defined capability with some self-service features, but is not yet treated as a first-class product with a developer-facing roadmap and formal adoption metrics.

What does 'time to first deployment' (TTFD) measure as a DevEx metric?
Time to First Deployment is a key developer experience metric for platform teams. It measures the onboarding journey: from a developer's first day (or a team starting a new service) to their first successful production deployment. A short TTFD indicates that the platform's golden path, documentation, and self-service templates are working well. Long TTFDs signal friction in the onboarding process.

The platform roadmap includes 'reducing toil for application teams.' What does 'toil' mean in this context?
'Toil' is a term popularised by Google's SRE book. It refers to work that is manual, repetitive, automatable, devoid of lasting value, and scales linearly with traffic or service count. Platform engineering's core value proposition is reducing application team toil — replacing manual environment provisioning, secret rotation, certificate management, and dependency updates with automated platform capabilities.

A platform team says they are 'treating the platform as a product.' What does this mean?
'Platform as a product' is a core principle in modern platform engineering. It shifts the team's mindset from 'we build tools when asked' to 'we run a product with internal customers (development teams)'. This means: understanding developer needs through research, measuring satisfaction (e.g., via developer NPS), maintaining a public roadmap, providing documentation and onboarding guides, and defining SLOs so teams can rely on the platform.
