A Project Planning board is used to plan project work. Each column on the board represents a project.You can make any changes to the board, move columns and cards around, and edit their content while the board is not published. When a board is published, it is mapped to a new Initiative that has the same name as the board. You can assign and track work for the new Initiative as with any other Initiative. When you publish a Board, the Board and the Items & Tasks are two views on the same data. Any changes made to the Items in the Initiative are automatically displayed in the corresponding board.
Note: This board type is designed to present projects as columns. Iteration information is not displayed in Project Planning board.
