In science and engineering, root cause analysis (RCA) is a method of problem solving used for identifying the root causes of faults or problems. [1] It is widely used in IT operations, manufacturing, telecommunications, industrial process control, accident analysis (e.g., in aviation, [2] rail transport, or nuclear plants), medical diagnosis, the healthcare industry (e.g., for epidemiology ...

[1] Traditionally, human errors are considered as a special aspect of human factors. Accordingly, they are attributed to the human operator, or user. When taking this approach, we assume that the system design ...

The person capable of identifying and solving the problem is seldom the usual operator. Because the timing of the malfunction is unpredictable, and both device or system downtime and engineers' time incur cost , the fault is often simply tolerated if not too frequent unless it causes unacceptable problems or dangers.
Operator "mis-adjustments" made the Free Fall ride unsafe prior to 14-year-old Tyre Sampson's death on March 24 at Orlando, Florida's ICON Park, officials say.
It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms. Determining the most likely cause is a process of elimination—eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that ...
