Question

Alex Jr. is getting frustrated as pizza delivery boy because his tips are so low. He does his best to get the pizza delivered in exactly 5 minutes; but it takes so long to take the order, prepare the pizza, cook the pizza, brick the pizza (for a nice gourmet crisp crust), and box the pizza that he can't get it delivered in under an hour. His boss asks Alex Jr. why it's taking him so long to get the pizzas from the order phase to the customer's door. What should Alex Jr. say is the cause of the long time?

Group of answer choices:

Only statistical fluctuations

Only dependent events

Both statistical fluctuations and dependent events

Alex Jr.'s boss accepted his answer about why it was taking so long to go from order-to-door. Now the boss has set up some customer service metrics. He wants to make sure that the time from order to door is less than 1 hour at least 90% of the time. Alex Jr. told his boss that he can get deliveries completed in 7 minutes or less 90% of the time. Alex Jr. is considering:

Both statistical fluctuations and dependent events

Alex Jr.'s implements the policy of getting pizzas delivered to customers within 1 hour of an order being placed 90% of the time. He makes some changes and gets the average time it takes to go from order to Alex's hands down to 53 minutes. Alex's boss thought that since Alex said he could get pizzas delivered in 7 minutes or less 90% of the time that the changes implemented would accomplish the goal of order to door in an hour or less 90% of the time. However, Alex's boss is upset to find that instead of 90%, they're just barely getting over 50%. Alex's boss comes to him ready to fire him for not keeping true to his promise. What does Alex Jr. use as the cause of the poor service quality?

Answer 1

Scenario 1. Alex Jr. is getting frustrated as pizza delivery boy because his tips are so low. He does his best to get the pizza delivered in exactly 5 minutes; but it takes so long to take the order, prepare the pizza, cook the pizza, brick the pizza (for a nice gourmet crisp crust), and box the pizza that he can't get it delivered in under an hour. His boss asks Alex Jr. why it's taking him so long to get the pizzas from the order phase to the customer's door.

Facts to be Considered:

1. The emotional state of Alex Jr.: FRUSTRATED
   Reason for Frustrated emotional state: LOW TIPS
   Reason for Low Tips: LATE DELIVERY
2. Delivery time: <= 5 Minutes
3. Order-to-door: >= 1 Hour

Implied Facts:

Order time+prepration+packaginging time: >= 55 Minutes

Solution: Only dependent events, because if the processing and packaging time could be under 55 minutes the delivery could be attempted within 1 hour.

Scenario 2. Alex Jr.'s boss accepted his answer about why it was taking so long to go from order-to-door. Now the boss has set up some customer service metrics. He wants to make sure that the time from order to door is less than 1 hour at least 90% of the time. Alex Jr. told his boss that he can get deliveries completed in 7 minutes or less 90% of the time.

Solution: Both statistical fluctuations and dependent events, because since his delivery is dependent on the time of order received to him, which might not be consistent, along with buffer for 2 minutes considering statistical fluctuation in the process.

Scenario 3. Alex Jr.'s implements the policy of getting pizzas delivered to customers within 1 hour of an order being placed 90% of the time. He makes some changes and gets the average time it takes to go from order to Alex's hands down to 53 minutes. Alex's boss thought that since Alex said he could get pizzas delivered in 7 minutes or less 90% of the time that the changes implemented would accomplish the goal of order to door in an hour or less 90% of the time. However, Alex's boss is upset to find that instead of 90%, they're just barely getting over 50%. Alex's boss comes to him ready to fire him for not keeping true to his promise.

Facts to be Considered:

1. New Policy for delivery under 1 hour with a forecasted success rate of 90%
2. The average time taken to receive the pizza for delivery: 53 Minutes
3. Perception of Alex's boss towards time to delivery: <= 7 Minutes
4. Achievement (Delivery under 1 hour) rate: ~<50%

Solution: Only statistical fluctuations, because since the preparation time to Alex's receiving time indicated is on average 53 minutes (with no defined upper limit) which implies half of the time (50%) time, but since time to deliver is around 7 minutes, giving less time for delivery by Alex; therefore the pizza delivery is delayed, 50% of the time.
