Some plants have planners, schedulers and supervisors, while others have stop planners and daily planners separated. A few keep electricity and instruments from mechanical planners, while some plants are more bare bones. It makes a big difference if the planner can 100% dedicate his or her time to planning, instead of having to take care of purchasing orders, train workers in the CMMS, attend improvement meetings, and so on. It’s the same thing with the supervisor role. Can he or she focus on their team or he/she expected to run a few improvement projects and renovations? The more we tack on to these roles, the less time will be left for leading their workers.
