What ordering requirements cannot be met by preconditions? Alternatively, what tangled knots will you weave as hard-coded sequences get into exception paths? I remember the evolution of Critical Path and PERT networks from I-J explicit links to predecessor links. Predecessors were much simpler and more flexible. And they could express any network that could be expressed with direct I-J links. And they didn't require the dummy nodes that I-J networks needed. While it's not exactly the same problem, I think it's the same conclusion with preconditions vs hard-coded sequences. Or to put it another way, Web business processes are conversations, not work flows. -Bob Haugen
