Workflow: the Human Aspect
Increasingly we need to be able to coordinate the interactions between real human actors in software—humans are, of course,
a key participant in almost every software system. In this article we will discuss why we want to implement human workflow.
We'll look at some of mon challenges faced when involving humans in structured workflow systems. Finally, we'll look
at a sample application that models a leave (or vacation) approval workflow showing some techniques municating with
human workflow actors using mechanisms familiar to them.
What Is Human Workflow?
