We'd use this as a tool for our configurable product. Example:
If a customer chooses Option 1 in Field A, they can no longer choose Option 6 in field B
Field A: Option 1, Option 2, Option 3
Field B: Option 4, Option 5,
A more concrete example for a company that sells different vehicles
Type of vehicle: Car, Motorcycle, Boat
Number of seats: 1, 2,
3, 4, 5, 6, 7, 8
This functionality could be a great asset for us in meetings with customers. It is always a challenge to describe what limits there are to the configuration possibilities of our product (it's a bit more intricate than the example). If we could show them how options become unavailable based on their previous choices that would be awesome! We're currently doing this by going through an excel-sheet with conditions in it together with the customer, but we'd prefer to move it into Aha as well.
(I'm sure there are many other possible dependencies you could describe with the different kinds of fields, but this is how we'd use it. Happy to help with some brainstorming if needed.)
