You start by scanning dashboards for safety, quality, throughput, efficiency, and service metrics. A line call comes in—machines are down. You arrive with schematics in hand, isolate the fault, update prints, and restore operations. Before lunch, you re-route conduit for a new piece of equipment and connect power. Later, you tweak PLC ladder logic to stabilize a control loop. By shift end, you've closed work orders, logged root causes, and captured every change in the drawings.
