Time taken/ time around time can be defined as the interval between the time of "job delivery to the system" and "job completion" for processing. Important PointsThe time to process an object is the actual time it is being worked on, whether the work is value- or non-value-added. The total of the processing time plus the time waiting and doing other non-processing activities will be the time it takes from start to end of any object that goes through the process. Processing time is the time it takes to complete a prescribed procedure; "they increased output by decreasing processing time"
