Roadmap — yes, you need a roadmap of the features. Do all the features fit in a program increment (PI)? Sometimes, features for a product span across two or more PIs … depending on the prioritization, sequencing of the features (sequenced to hit a hard date/milestone, for example) and how large the Epic or Capability or Product that is going to be built.
Usually, a PI is a quarter of a year long… 3 months long… 6 to 7 iterations (sprints)… 12 to 14 weeks long.
Lay out the features over the roadmap (over a PI or series of PIs).
Once you have this ‘big picture’ with features laid out on the roadmap to success, you can now go to the next step.
