A manager wants to determine the number of containers to use for incoming parts for a kanban

system to be installed next month. The process will have a usage rate of 80 pieces per hour. Because

the process is new, the manager has assigned an inefficiency factor of .35. Each container holds

45 pieces, and it takes an average of 75 minutes to complete a cycle. How many containers should

be used? As the system improves, will more or fewer containers be required? Why?
