It is not easy to hold this kind of quality leadership for three big reasons. First, no one will believe you have the longest-lasting trucks until they have already lasted a long time on the road. Itâs a reputation that takes a while to earn and can be lost quickly. Second, designing a very high-quality piece of machinery is not a textbook problem. Designers learn from other designers over time, and the company accumulates these nuggets of wisdom by providing a good, stable place to work for talented engineers. Third, it is usually quite difficult to convince buyers to pay an up-front premium for future savings, even if the numbers are clear. People tend to be more myopic than economic theory would suggest.
