2707 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

41 questions in Platform Engineering.

  1. Inner Loop & Outer Loop intermediate Multiple choice

    Sixty engineers each wait for a build roughly 15 times a day. The build takes 4 minutes. Roughly what does that cost a year, and what does the number rule in or out?

  2. Inner Loop & Outer Loop intermediate

    What distinguishes the inner loop from the outer loop, and where should a platform invest?

  3. Internal Developer Platform intermediate

    Review this. A 12-engineer startup with 6 services has built an internal developer platform - a React portal, a YAML DSL that generates Terraform, a bespoke secrets service backed by cloud KMS, a service catalogue and a maturity scorecard with 23 checks. Two of the twelve engineers work on it full time. Deploys take 14 minutes and the DSL covers about 60% of what teams need, with the rest hand-written Terraform merged by those two engineers. What would you remove, what would you change, and what would you leave alone?

  4. Internal Developer Platform intermediate

    Your service catalogue says every service has an owner. Investigating an incident, you find the named owner left the company eight months ago. How do you prevent this class of problem?

  5. Paved Road & Golden Path intermediate

    A team says the golden path cannot support their workload and wants to build their own deployment tooling. How do you respond?

  6. Paved Road & Golden Path intermediate

    Review this golden path. A new service starts with a portal form of 34 required fields; an architecture reviewer approves it within two days; the generator then creates a repository with build and deploy wired in. It does not create the database, the DNS record or the on-call rota, which are three tickets taking four to nine days. In the last year 18 of 60 new services went through it. What would you remove, what would you change, and what would you leave alone?

  8. Platform Adoption intermediate

    A platform capability is objectively better than what teams are doing, and adoption is low. How should the gap be diagnosed?

  9. Platform Adoption intermediate

    A platform team reports 90% of services are on the platform, and delivery has not improved. What is being measured wrongly?

  10. Platform API Deprecation intermediate

    A platform must deprecate an API or capability that many teams depend on. How is this done without destroying trust or stalling indefinitely?
