With the ProductPlan Master Plan feature, teams can consolidate multiple roadmaps into a single comprehensive view. With the Master Plan feature you can create new views and share them with executives and others. A Master Plan is view-only, so each product manager retains control of their underlying roadmap.
You can create a New Master Plan from your roadmaps page. Select the roadmaps you want to include and then set the timeline and dates you want to display. You can either choose to retain the original bar color scheme for each roadmap or give each roadmap a unique color. You can share your Master Plan just like you would share any roadmap.
