問題文
A manufacturer has four developers and two administrators. Deployments happen whenever a developer is free, sandbox refreshes are requested ad hoc, and nobody owns the promotion path. Which option correctly identifies the missing roles together with the right statement about them?
選択肢
- A release manager and an environment manager; both are accountabilities that can be assigned to existing staff before any tooling is bought.
- A dedicated build engineer and a dedicated database administrator, because the promotion path cannot be owned by anyone who also writes code, and because the platform requires a database administrator to manage storage growth across the sandbox estate.
- A project manager and a scrum master, one to run the plan and one to run the ceremonies.
- No roles are missing; the team simply needs a written deployment checklist that any developer can follow, which is cheaper than adding accountabilities and avoids creating a bottleneck around one person.
