I want to know how to draw a cross-functional chart (CFC) for a new mobile app development, which involves more than one actor who play different roles, an example would be an app for food ordering from nearby restaurants.

The actors - the app owner, restaurant owners, restaurant staff, delivery boy and general user.

I am stuck in the very initial stage. They issues I am facing are:

1.     Can CFC be built to represent such a scenario? Is it feasible?

2.     If no, what are my other options?

3.     If yes, what level of role detail we can show in the chart.

4.     Next, when I started to build the chart I was trying to put the first step of User registering from the app. Here, all the actors require registering, so how do I show his? Do I make a separate box for it under each actor’s swim lane, or I can only draw one box in total.

5.     If I draw only one box, then in which swim lane that box will be and how would I connect them.

6.     Other roles of the actors could be this

Can you can help me to get started here.
