Backlog planning
If the project uses Releases, it is convenient to plan the release backlog with the "Release planning" module. In the filter settings you can select releases, including the "None" option, to show cards from the backlog:
Using the priority and effort estimates already set, you can distribute stories from the backlog across future releases. The release column shows its planned start and finish dates, and the amount of requirements that can be completed at the given team velocity. Team velocity is set for each release separately and is determined from previous team velocity figures.
Iteration planning, that is, the order in which stories are done inside one release, is done in the "Iteration planning" module. The module works like "Release planning", except that the columns show the selected iterations.
In the "Product discovery" (Scrum) and "Product development" (Scrumban) processes, sprint planning also breaks stories down into work items (tasks).
