*Intended learning outcomes: Describe the order of the operations of a production order, operation time and operation load, the elements of interoperation time, administrative time, and transportation time*.

*Time management* is the observation, control, and manipulation of time elements. *Time elements* are the duration of operations, interoperation times, and administration times.

In typical job shop production, the focus is on interoperation times, since they make up more than 80% of the total lead time. However, in line production, observation of the duration of the operations themselves is also of particular interest.
