In Visio 2k Ent, you can create DFD's as models. There is a nice
decomposition option for the processes and some degree of flow balancing.
Considering my $3k license for Popkin doesn't have that feature working.....
Anyway, things get sloppy when in a Context Diagram (the top level) I have
one flow with two arrow heads representing ALL flows between the system and
an external entity.
This makes for a neat clean diagram.
Then when it's time to decompose and add more details as I now have major
sub processes of the System, I get into trouble.
1. What do I do with the flow brought down?
2. What do I do with the detailed flows created down that are showing errors
as they don't go up?
I don't seem to recall having this issue in Visio 4.5.
