A) The Service Reusability principle is applied and the service capability candidate is split into two service capability candidates. This increases the reusability of the service capability candidate because each provides a distinct and generic function that can be individually reused. and B) The Service Autonomy principle is applied to help determine whether the shared e-mail server and database may raise autonomy-related problems that may impact how the service capability candidate should be modeled. and C) The Service Discoverability principle is applied to more clearly define the purpose of the service capability candidate so that information is collected for future discoverability purposes.

D) The Service Statelessness principle is applied so that the service capability candidate is designed and developed to defer its state data to e-mail messages and a corresponding database table as part of the overall physical service architecture.
