Note - S88 is very flexible, but many practitioners seem to follow an approach focused on the Equipment Modules, with phases running in them. 
There is another equally valid one where phases run in the Unit.
ControlDraw can handle either approach, in fact it can have both in the same model. 
You can download a ControlDraw Model demonstrating this from the Download page. This model contains a Process Cell and two Units, based on many examples on the web.

And one to make you think. OK, it's from a Web company but it rings bells
"Visual design first, programming second. The more traditional process is starting from the abstract (documentation, diagrams, charts, etc.), coding a skeleton app, and then homing in on the real by finishing it up with an interface. We think thats backwards."
Getting Real, Step 1: No Functional Spec
"Dont write a functional specifications document. Why? Well, theres nothing functional about a functional specifications document."
