It doesn't matter much anyway...
all they're trying to do is to come up with an object database of the optimal process for every possible business. Unfortunately, anywhere there are humans involved, the optimal process is degraded by mistakes and lack of 100% productivity. After all, the optimal process would be wholly automatable - no humans required.
I agree with the others, BPM is a waste of time...unless they can do a stopwatch run on the new process that's faster than the previous process and doesn't detract from productivity - but that's an engineering process (tiny revisions to the model) rather than re-doing the entire process and hoping it works not only 100%, but better.
And don't forget that all the while, the poor users are trapped in the middle trying to hang on to their jobs. Change things, and productivity automatically drops.
This is not good business. Good business is not changing the production floor until the new process model is proven to be more effective than the previous model.
Business rules to live by:
1. If it ain't broke, don't fix it.
2. Don't break anything (you idiot).
3. If you break it, you buy it (and you're fired).
Live by these rules and you already have the optimal process, which has been in place for time immemorial. BPM is making management people forget rule #3 (especially when they change the production floor with unproven ideas).
