"This has happened to me numerous times. Normally when presented with a problem regarding my processes, I am able to find the root cause fairly quickly. However, sometimes there are problems that are very difficult to diagnose. When asked to solve a difficult problem, I will always engage the team members and maintenance team who work in the area to see if we can work together to establish the cause. If that is not successful, I will escalate to my management and other more experienced engineers in the organization. If we cannot come to a resolution with those steps, I will engage the equipment vendor or other outside experts for help. "

"My next step would be to consult various experts within the company. If no solutions arise internally, I would escalate the issue to a manufacturer or expert. If there are none available or a solution is still not established, I would request management hire an external professional."
