The assignment discusses the make or buy decision, which involves selecting between manufacturing a product or purchasing it from an external supplier. The decision is influenced by factors such as quality, quantity, convenience, and marketing. For Playdough Company, making canisters in-house could provide better quality, but purchasing from a vendor might be more convenient if there's no high demand. The company should consider its current capacity, effective quality control, and proprietary technology when deciding whether to manufacture or purchase the product.
