A telephone is assembled from a handset and a base. The handset in turn is assembled from a handle and a cord, and the base is assembled from a case, a circuit board, and a face plate. A BOM and a sketch of the phone, along with the numbers of parts on hand and lead times, are shown as follows.

a. Management would like to start assembling phones as soon as possible. How many phones can be made from the available parts, and when can they be delivered? Construct a materials plan to show your answer.
b. For the materials plan constructed in part a, develop an inventory projection of parts and finished goods on a week-by-week basis.
c. Suppose another 100 circuit boards can be obtained within one week. What effect will this have on your answer for part a?
