An important aspect of understanding your business ecosystem is knowing your position within it (positioning), whether you hold a higher or lower (subordinate) role, and whether your offerings are substitutes or complements. Netflix started as a DVD rental service. With the rise of online streaming, Netflix saw it as a replacement for DVD rentals. Kimbap and Ramen are complementary goods, but Ramen and Udon are substitutes. This is why, even when setting up a snack bar, paying attention to the menu is crucial. Complementary goods increase sales, while substitutes are more likely to lead to no change or even a decline in sales. - Joseph’s “just my thoughts”
A big supermarket can do business in the suburbs because of wheels. If someone asked me what is one of the greatest inventions in human history that civilization has ever developed, I would say "wheels." The automobile is also a wheel. Shopping carts are also wheels. Without wheels, how many people would go far and carry heavy loads? Mass distribution is possible because of wheels. To do bulk sales, you have to have a lot of inventory. That means you need a lot of storage space. It also means you need cheap real estate. The trivial circle, the wheel, is the key to solving all these constraints in one shot. - Joseph’s “just my thoughts”
