質問 9：
Project Team Alpha delivers Service A for Solution 1. Project Team Beta delivers Service B for Solution 2. Some time later, Project Team Omega wants to reuse Service A and Service B for its new Solution 3. How would Services A and B need to have been designed in order for Project Team Omega to successfully reuse these services without having to resort to a major integration project?
A. Service A needs to be designed using a different vendor platform than ServiceB. This enables vendor diversity, thereby guaranteeing interoperability.
B. Services A and B need to be standardized and designed with an emphasis on intrinsic interoperability so that they are compatible regardless of when or by which project team they are delivered.
C. Services A and B need to reside on the same physical server or workstation, thereby allowing them to be reused without the need for major integration effort.
D. Services always require the use of transformation technologies in order to communicate. Therefore, major integration effort is unavoidable in this scenario.
正解：B
