Is there a name for a group of views that are related by state, and hierarchical?

Example: I have an SPA Angular app.

There is a sale process which includes views for:

1. Choose Customer
2. Add Items to Work Order
3. Cash Out Sale

These are related. You have to access them in order. I am confronting things like, state between routing, how to handle someone inputting URL to step 3, etc..

To research I would like to know if there is a name to this grouping?
