Chapter 4 Building an Analysis Business Process Model
A fork is the splitting of an input flow into several output flows executed in parallel. It creates several concurrent branches below its symbol. The processes associated with each of these paths continue in parallel.
A fork should have only one input flow and have more than one output flow.
It is a complex flow within which one source process is replaced with two or more destination processes, each of which representing an independent flow.
It is equivalent to several flows outgoing from a process with guard conditions on each flow.
