Just imagine that any dialog and conversation inside an organization do through a Workflow engine inside organization portal. Actually this is a full structured dialog that can hire BPM for incremental improvement too. This means any request an communication must be defined (may be BPA is here) before using and you have to sit back of your computer, close your Gmail and just answer to tasks in your dashboard.
Is it means you don not need to send email, write on paper, answer phone or speak with your college!!!. What is wrong ? Is it possible?
