I would like to strongly suggest you considering some sort of workflow capability available. My application provides solutions where tasks (Individual and concurrent) are spawned and we have to track the requests, users, and integration with underlying applications. This is all done manually or custom coded. 

If there was a way to have out of the box workflow capability, that would make the life so much easier. Having drag and drop features to create workflow diagram, use the rad screens to create forms, and integrate with underlying applications.

Please let me know if a workflow engine is in the roadmap ?
