What should be done immediately after a daily test failure?

After a daily test failure, the appropriate course of action is to report the failure and wait for instructions. This approach is crucial as it ensures that the situation is documented and communicated effectively to relevant personnel who can provide guidance on the next steps. Reporting allows for a thorough assessment of the failure, including understanding the nature and severity of the issue, and it helps in maintaining safety protocols by not allowing unqualified personnel to make hasty decisions that could exacerbate the situation.

By waiting for instructions, you allow qualified individuals to analyze the data, evaluate the root cause of the failure, and then decide on a safe approach for either resolving the issue or performing additional testing. In settings such as engineering or technical operations, following the established protocol is essential to maintain safety and operational efficiency.

In contrast, contacting the train engineer might delay the necessary reporting process, conducting another daily test could lead to repeated failures without understanding the underlying issue, and resetting the system might obscure valuable diagnostic information needed for an accurate assessment. Thus, the most prudent action is to report the failure as part of a structured response plan.
