This question I ask myself again and again, when I work with one or the other BPM system. Is why so many systems no reasonable "Outbox" for all of my edited processes implemented?

I think it's from the user point of view extremely interesting to know where my processes are straight. Especially in processes that I have myself initiated, eg the classic "vacation request". I want to know just if my supervisor has approved my proposal, or whether he was still unfinished when he is in the inbox and if I should just call times. Of course I get a notification from the process automatically as soon as my application has been processed. But what about the period up to the editing?

Even if I want to investigate is a very interesting Outbox. For example, if a customer calls and inquired about the status of his order. Then we could have such content and the outgoing current status of the process and give the customer simply retrieve the desired information.

A highlight was, of course, if I could use processes from the Outbox as a template. So I might as my travel expenses from last month, simply "copy", possibly adapt some information, and would save me a lot of work.

There would be enough in small dashboard for the normal user. On this dashboard, the status of the last processes to be displayed and if necessary the user can view further details (drill down). This would save some calls to the helpdesk, which ask the user for where their processes are stopped and all significantly increase the transparency of a BPMS.
