I've met Tom Baeyens and Joram Barrez in the last edition of Devoxx. Their talks were a "must attend" section in all recent Devoxx editions, and they will probably present their brand new product at this year's edition too. The framework is still in alpha but I think it will evolve a lot until there. By the way, the current version is more about playing and understanding the idea than effectively performing processes. What I've seen so far deserves some comments.
My first impression was nice. Activiti is very simple to install and the team made a very good work on the design of the user interfaces. Of course, I cannot be so critical right now because it is just beginning, but I will follow the project from now on to give constructive feedbacks to the team.
- the performance of the user when executing his/her activities; and
- the quality of the data inserted.
