The flow rate through a process is 0.5 flow units per minute. The number waiting for the process is 1 . The time to do the activity in the process is 1 minute. This is a stable system. The average amount of time a flow unit spends waiting for the activity is Enter one integer (which can be 0 ) and ONE decimal, so the answer looks like X.X. Any of the Xs can be a 0 . No. Remember that Little's Law is I=RT, so T=I/R= flow units waiting divided by the rate at which flow units go through the system. The flow rate through a process is 0.5 flow units per minute. The number waiting for the process is 1 . The time to do the activity in the process is 1 minute. This is a stable system. The average amount of time a flow unit spends waiting for the activity and doing the activity = Enter one integer (which can be 0) and ONE decimal, so the answer looks like X.X. Any of the Xs can be a 0 . NO. Calculate the time spent waiting for the activity and add in the time spent doing the activity. It is the total of these two activities that is the
