We use Openflow: http://www.openflow.it to manage enormous workflows with many dozens of states/activities and hundreds of process instances going through. Works well when you find your way to use it. Some points to consider if you are considering using it for something serious: - it is not very actively developed/maintained at present - the documentation is not detailed/usable enough, you'll have to "read the source" to find out how things work sometimes - one needs to think more than twice about how to store workitem data and how to bind it to the workflow instance - otherwise it'll bite badly when you have hundreds of process instances ant thousands of workitems in your system - openflow heavily relies on Catalog. When upgrading Zope or installing new indices etc test thoroughly what you have in your workflow for integrity - do not trust the visual design tool (the OpenFlow Editor), check your activities/transitions yourself.

All,

Are there any workflow products available for Zope 2.x that do not require either Plone or CMF? It looks like there aren't but I thought I'd ask first.

Thanks, Tom
