1. Consider a value stream map for the order posting and fulfillment process in a restaurant shown inExhibit 7.7. The chef's time is valued at $30 per hour, oven operation at $10 per hour, precooking order waiting time at $5 per hour, and postcooking order waiting time at $60 per hour. The $60 estimate reflects the cost of poor quality for a dinner waiting too long that might be delivered to the customer late (and cold). Suppose that if the restaurant uses iPads to place orders and notify waiters when thecustomer's order is ready, the time on the order board (now an electronic order board) decreases from 5 minutes to 1 minute, and the prepared order wait time decreases from 5 to 4 minutes. Recompute the total value-added and non-value-added time and cost for this scenario. Round your answer for the total revised time to the nearest whole number and round your answer for the total revised cost to three decimal places.
2. An express checkout line at a grocery store takes an average of 3 minutes to ring up a customer's order. On average, nine customers are in the checkout line. What is the average number of customers per hour processed in the checkout line? Assume that there are multiple express check out lines in the store. Round your answer to the nearest whole number.
3. (a) An accounts receivable manager processes 150 checks per day, with an average processing time of 15 working days. What is the average number of accounts receivable checks being processed in her office? Round your answer to the nearest whole number.

(b) What is the average number of accounts receivable checks being processed if, through information technology, she reduces the processing time from 15 days to 10 days? To 5 days? Round your answers to the nearest whole number.

(c)What are the advantages and disadvantages of adopting this technology? The new information technology-Select- (Delays/Speeds up)the process and simultaneously Select- (increases/lowers)the average number of checks (WIP) in the office. This means-Select- (less/more)cash sooner in their accounts.

4 . A manufacturer's average work-in-process inventory for Part #2934 is 795 parts. The workstation produces parts at the rate of 210 parts per day. What is the average time a part spends in this workstation? Round your answer to two decimal places.
