As with most thing there is a problem of scale.

Representing a simple recipe as a process may work, but try modeling an increasingly complex system (say your simple local football players tracking system, to something more extreme like a payroll system or an aircraft traffic control system) in such a way.

It has been tried before with limited success during the decade of structured analysis and dataflow diagrams.

Isn’t such an approach suited to simple transformational problems only?
