Workflows are modeled on a pretty fine level of granularity using the standard BPMN 2.0 version (and later versions). BPMN is both business ready and technically detailed enough to allow model processes to be executed in a process engine. Oracle fittingly expresses the mechanism as what you see is what you execute.

Those workflows typically orchestrate human interaction through human tasks and functionality through SOA services. The next chapter discusses BPMN in greater detail.

In the next sections of this chapter, we will move our head out of the cocoon of the silo, looking higher and higher along the hierarchy of the enterprise until we reach the world of workshops and polished PowerPoint slides in which the strategy of the organization is defined.
