Question 13 1 pts If you need to refresh your memory, go back and watch the video from Week 3: Process Flow. This video is intended to help you understand how queues can occur even if utilization is (on average) less than 100%. This queueing occurs due to variability in arrivals and/or processes and is known as the CURSE OF VARIABILITY. The more variability there is the longer the average wait time. What would happen in that video if the WIP limit were set at one job? (Meaning that if a job arrives and there is already a job in the system, then the arriving job is rejected.) There would never be a queue. The waiting time could be up to one minute, The queue could be no larger than one job. There would always be a queue.

This queueing occurs due to variability in arrivals and/or processes and is known as the CURSE OF VARIABILITY. The more variability there is the longer the average wait time. Thus one objective of Lean Operations is to remove this variability (to the extent possible) to thereby reduce the waiting time. What type of variability does lean op's work to reduce? Variability in process times only. Variability in interarrival times and process times. Variability in neither interarrival times nor process times. Variability in interarrival times only
