Double update/review process

[jeffw]

Im wondering how (or if) I could model the following scenario:

I have a scenario where when a process is started, it goes through a review/update step. For example, a customer and salesman can both review and update an order; If either changes its details, then the other needs to review it again.

How could I do this?

Here's my suggestion. The general idea is to have a review task for each actor in the process and require a certain number of confirmations. If the number is not reached, the review process is started all over again.

I modeled this with the GPD. If you want a copy of the process project, drop me an email and I'll send it to you.

I might as well paste the contents of gpd.xml here.
