A business process is defined as a unit of internal behaviour or collection of causally-related units of internal behaviour intended to produce a defined set of products and services.
A business process describes the internal behaviour performed by a business role that is required to produce a set of products and services. For a consumer the required behaviour is not of interest so a process is designated "internal".
The name of a business process should preferably be or contain a verb in the simple present tense.
