The various elements of Paccar’s strategy are not general purpose—they are designed to fit together to make a specialized whole. The design is clearest if you imagine a truck manufacturer assembled out of generic bits of various truck companies, a sort of Frankenstein’s monster truck company. With medium-priced truck designs aimed at fleet buyers, dealers aimed at picky owner-drivers, and design engineers trained to cut costs to the bone, it would not last long. Good strategy is design, and design is about fitting various pieces together so they work as a coherent whole.
