This is how we worked in 1906:
The difference? The tools are better, some I even like a lot! But where is the flow? An e-mail notification? A reminder alarm?
To attain a flow you need a riverbed for the flow of information - information representing real life objects: Parts welded together, products moving, invoices created, health records updated, x-rays taken, pills dispersed...
The riverbed needs to deliver workorders, pertinent information and the tools at the same time in the same interface and to the right person - then when finished it has to deliver all needed to the next person... and so forth.
A bit like this:
One single flow - but now beyond the pure production line; with user induced dynamics, loops and branches befitting a more human and creative environment.
That's why we tinker with the thingamy :)
