1. A project management system having a user interface, the user interface comprising: a first output view subsystem, operatively coupled to a database containing information related to a project, the first output view subsystem adapted to provide a perspective view of a three-dimensional depiction of a pie comprising a plurality of slices, a plurality of layers, and a plurality of cells, wherein each slice represents a stage of the project and each cell is formed by an intersection of a slice of the plurality of slices and a layer of the plurality of layers; the perspective view further comprising a first layer view representative of a first subset of the information related to the project and comprising a first set of cells associated with the first subset of information, the first subset of information corresponding to a first tab of the user interface; a second output view subsystem, operatively coupled to the database, the second output view subsystem adapted to provide a second layer view representative of a second subset of the information related to the project and comprising a second set of cells associated with the second subset of information, the second subset of information corresponding to a second tab of the user interface; and a third output view subsystem, operatively coupled to the database, the third output view subsystem adapted to provide a third layer view representative of a third subset of the information related to the project and comprising a third set of cells associated with the third subset of information, the third subset of information corresponding to a third tab of the user interface.
