Project Team Alpha Delivers Service a for Solution 1

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) Services always require the use of transformation technologies in order to communicate. Therefore, major integration effort is unavoidable in this scenario.
B) 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.
C) 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.
D) Service A needs to be designed using a different vendor platform than Service B. This enables vendor diversity, thereby guaranteeing interoperability.
