Hi!

Is there any problem of using CMFOpenFlow as the default workflow engine
into ERP5?

Hi!
Is there any problem of using CMFOpenFlow as the default workflow engine
into ERP5?

Yes, there is a problem from a business point of view:
- a high cost (time, money) due to the requirement of rewriting many
pieces of code
- no benefits in practice for (paying) users and customers

The reason why there is no benefit for users and customer is that any
business process can be implemented with DCWorfklow. This is due to the
fact that nearly all business processes are based on documents which
circulate in the company. What is great with DCWorfklow approach is that it
allows to implement consulting approaches with customers in a quite natural
way for non engineers : simply look at documents, look at stamps,
signatures, history of decision... and voila... the workflow is made. After
implementing more than 50 workflows in about any business area, I can tell
that DCWorfklow is far enough for running a business.

Also, one should note that there is no difference between activity workflows
and document workflows from a theoretical point of view because there is an
isomorphism between the two.

So, it is not an option for me now to spend time migrating to CMFOpenflow. I
prefer spending time writing documentation or improving the LiveCD business
templates, which is what customers request.

What would be interesting is having a good Webdav interface to DCWorfklow so
that it is possible to modify a DC Worfklow online with any XMI compatible
tool.

In the future, there might be an interest in using CMFOpenflow, if there is
a migration path (for example through XMI) and if CMFOpenflow provides
features which customers request (and are ready to pay for).

JPS.

JPS.

I asked this question because many people model process (workflows) using
activities, instead of states. Also, some patterns are based both on
activities and states.

But it is ok, it is not so painfull to convert from activities to states
(the activities become the transitions).

Bye for now,
