One core duty is to observe operation of equipment to ensure continuity of flow, safety, and efficient operation, and to detect malfunctions. On the six-type interest model it reads RCI, meaning hands-on work with tools, machines or the physical world comes first, followed by orderly work with data, records and clear procedures.

If you want hands-on work with tools, machines or the physical world, keep it on your list. If you need creative work with room for original expression, it may feel thin.
