Servicio de Proceso de Negocio

De acuerdo con IBM, "A business process represents a sequence of activities that accomplish a business goal. Such a process can be represented as a service. For example, the process for applying for a loan at a bank can be represented as a business process service. Some more examples of business process service are createStockOrder, reconcileAccount, renewPolicy. Business process services are likely to be composed from other services and can themselves be composed into more complex or more coarsely grained business processes".

En este caso se puede considerar un servicio a todo un proceso de negocio orquestado a partir de realizar una composición de servicios (pertenecientes a las tres otras categorías) en lo que se conoce como orquestación o coreografía (cuando se componen servicios del negocio con otros asociados, proveedores, etc.)
