Claude Code config scenarios — CCA-F Exam Prep

Three teams. Three Claude Code setups. Two of them broke.

A startup, a mid-size team, and an enterprise pipeline all deployed Claude Code the same week. By Friday, only one was still running smoothly.

The startup's solo dev accidentally wiped a production database. The enterprise CI/CD pipeline approved a PR that deleted all authentication middleware. The mid-size team? Zero incidents.

Same tool. Different configurations. Wildly different outcomes.
