Robert Products Inc. consists of three decentralized divisions: Bayside Division, Cole Division, and Diamond Division. The president of Robert Products has given the managers of the three divisions authority to decide whether to sell outside the company or among themselves at an internal price determined by the division managers. Market conditions are such that sales made internally or externally will not affect market or transfer prices. Intermediate markets will always be available for Bayside, Cole, and Diamond to purchase their manufacturing needs or sell their product.
