Multi-homing is the centerpiece of cross-functional collaboration in Asana. Your most important work happens with team members from other departments—who each have their own way of storing and organizing to-dos. With multi-homing, you can house the same task in multiple projects (rather than creating duplicates of the task, which can quickly get outdated). Then, if you change any task details in one project, those changes are instantly and automatically reflected across every other project in real time.
