answer the following questions with the data provided. Show calculations by illustrating using the funnel model. Sales = 90 units/month (In flow) Production = 90 units/month (outflow) Backlog = 225 units Production time = 2 weeks a. What is the throughput time (total wait time) given data above (show calculations) (5 pts) b. For the next 3 months, sales are expected to increase to 150 units/month, after which it will return to 90 units/month. Production will remain the same at 90 unit/month during this time. At the end of 3 months what will be the backlog and total wait time? Show calculation for credit (5 pts)
