Zone of Pain Consider a component in the area of (0, 0). This is a highly stable and concrete component. Such a component is not desirable because it is rigid. It cannot be extended because it is not abstract, and it is very difficult to change because of its stability. Thus we do not normally expect to see well-designed components sitting near (0, 0). The area around (0, 0) is a zone of exclusion called the Zone of Pain.
