Information systems, especially more complex systems,
are what analysts refer to a asynchronous. By this
they mean that many things can potentially happen at
the same time (and that often there are many
branchings of flow).

Note: Written text by comparison is a synchronous
tool: It is meant, in the main, to document tasks
(processes, functions, whatever) happening serially
(i.e, one-thing-after-another).

There is really only one graphic (visual) tool that
specifically addresses the very common problem of
trying to rigorously document an asynchronous system.
Business Analysts use this tool all the time. For a
very clear and easy to read discussion of your issue
and how to address it, I highly recommend the first
few chapters of Structured Analysis and Systems
Specification by Tom DeMarco. It is an older book,
but, I have found nothing like this that so clearly
discusses this issue and how to address it.

I use this tool to capture AND verify (i.e., walk
through)the asynchronous behavior of a system (and
also to properly modularize (i.e., structure or
organize) my understanding of the system). This
provides me with a excellent way to organize my text
documentation. And I often include such graphics in
conjunction with my text - a real powerful way to

Does anyone know of a way to visually indicate that
some steps in a process can be performed at the same
time. I've shown this in a Visio diagram using
the double vertical lines, but I want this to also
be clear in the text of the process document.
