Speaker Kits, Inc., packages high-fidelity components for mail order. Components for the top-of-theline speaker kit, “Awesome” (A), include 2 Bs and 3 Cs.

Each B consists of 2 Ds and 2 Es. Each of the Cs has 2 Fs and 2 Es. Each F includes 2 Ds and 1 G.

It is an awesome sound system. (Most purchasers require hearing aids within 3 years, and at least one court case is pending because of structural damage to a men’s dormitory.) As we can see, the demand for B, C, D, E, F, and G is completely dependent on the master production schedule for A—the Awesome speaker kits.

APPROACH c Given the preceding information, we construct a product structure and “explode” the requirements.
