A few real-world style situations from depot/fleet ops, see how you'd handle them. Drop your answers below and I'll comment back on a few with my take.
1. The Cold Morning
Freezing temperatures overnight have caused a handful of units to develop faults. You've got a full diagram to get out and limited engineering resource. What's your first move?
2. The Conflicting Priority
You're mid-task when Control asks for something urgent that clashes with a safe system of work already in place. How do you handle it?
3. The Small Thing Nobody's Flagged
You spot something during a routine check that isn't a problem yet, but could be in a few weeks if left. Do you raise it, and to who?
4. The Unexpected Situation
Something happens on site that's outside the normal routine, not an emergency, but not standard either. What's your first priority?
Comment your answers below, even a rough one-liner. I'll jump in and reply to a few with how I'd approach it.
