Studying Work as a Process When practitioners conduct a time study, it is essential that they know what they want to study Work is not strictly a set of disconnected tasks, it is a process These processes have names, such as maintenance or transfers, and begin with inputs, move on to processes in which inputs are modified, and conclude with.
With respect to changing a grinding wheel on a surface grinder, OSHA says the wheel change takes place outside of the normal production process: ie, the machine is turned off, grinding operations stop, a guard is removed, and the wheel retainer nut is loosened and removed.
