User Story maps should be able to show Master Features and Features from multiple products.
We have complex products that have to work together in order to deliver usable solutions. Any step that the user does (install, configure, receive certain data, etc) requires work on multiple products (hardware devices, firmware on those devices, software user interface, data collection system) to make the solution work.
Our Master Features always contain Features spread across multiple products.
The User Story Map seems to be a great way to visualize how the Features within a Master Feature are delivered over multiple releases, but if we can’t actually see all of the Features under that Master Feature, it loses the value. We would love to have a better way to visualize the relationship between Master Features and Features.
