DISCUSSION QUESTIONS
1. Some responses from each functional area could include:
❑ Marketing: The available-to-promise quantities because they determine when
orders can be promised to customers and the history of orders accepted for each
product by time period because this information can be useful in projecting future
demand patterns.
2. A master flight schedule specifies the arrival and departure times for all the flights an
airline must produce to meet customer demands. Here, the lead time is the time
aircraft.
3. The purpose of this exercise is to get the students to think about the usefulness of
ERP for each of their major areas of interest. Because groups consist of different
functional area representatives, the discussion is intended to emphasize the cross–
functional needs that are satisfied with an information system such as ERP. Some
responses to this exercise include:
❑ Marketing—information about the availability of finished products that can be
promised for delivery; finished goods inventory performance (service levels,
stockouts).

The first order for 500 (in week 4) should be accepted. Through week 4, on hand
(400) plus three MPS quantities of 500 each = 1900. Of those, (300 + 350 + 250 +
250) = 1150 have been sold, leaving 750 available (250 after this commitment).
b. The second order for 400 (in week 5) should be accepted. Through week 5, the
250 remaining after the first order plus one more MPS quantity of 500 = 750. Of
those, 200 have been sold in the 5th week and 150 in the 6th week. Therefore,
(250 + 500 – 200 – 150) = 400 are still available. There will be zero units
remaining for sale even after accepting this order.

Decisions on the arriving orders:
❑ Order 1 for 15 units in week 2 should be accepted because there are 25 units ATP
from week 1. After this order is accepted 10 units remain in ATP from Week 1.
❑ Order 4 for 75 units in week 7 should be accepted because there will be 65 units
in ATP from week 6, which, along with the 10 units that continue to remain in
ATP from week 1, will be adequate to fill the order completely.
