The numbers next to each activity are processing times in minutes. Table 5.16 shows the assignment of workers to activities. a. Calculate the capacity of the process in jobs per hour. b. Management is considering adding one worker to the process, but this would increase the operational cost by $23/h. Management knows that increasing the process capac- ity by 1 job/h adds $30/h to the bottom line. Based on this information, would you recommend adding a worker, and if so, with whom should the new person work?
