Microsoft barks up the (wrong) workflow tree
I see Microsoft has gone all gooey over workflow. Global centralised workflow is on a hiding to nothing for all but a very small subset of applications where people sit closely together and work on very concretely defined processes.
Most business processes are messy, lossy, and exception based. They thrive on loosely connected peer-2-peer type communcations mechanisms like Instant Messaging, email, SMS and telephone. When workflow starts to take account of these conditions it will take off, until then expect much flag waving and little progress.
