How would you implement a software Andon Cord equivalent?

This tests translating Lean manufacturing stop-the-line principle into software delivery and culture. A strong answer defines the trigger as any automated quality gate failure, such as compilation errors, failed unit or integration tests, or analysis violations. Immediate effect: a hard stop of the CI/CD pipeline, blocking new commits until resolution. Team response: a swarm with collective ownership to fix the root cause immediately, never scheduling a workaround. Red flag: blaming the individual or treating broken builds as noise.
