I built Service Composition A, which is comprised of 4 services. It was very successful in that it fulfilled all of its expected business requirements. I was then assigned a new project that required me to deliver a new service composition called Service Composition B. After studying the new business requirements, I realized that one of the services in Service Composition A could be reused "as is" in Service Composition B. However, when I tried to make it part of Service Composition B, I ran into a number of problems. In the end, it turned out that even though the service was reusable, it was simply not designed to participate in more than one service composition. Which service-orientation principle would have addressed this issue if I would have applied it to the service prior to completing Service Composition A? Select the correct answer.
