Careful organization can generally achieve a good balance between density tree depth. Small screens, in particular as found on phone devices, suffer because click resolution is limited by the size of a finger tip. Another enemy of usability is frequent reorganization of commonly used pages. If one must always look for commonly used links because they move around, efficiency suffers. In my observation, attempting to achieve high density results in more frequent adjustments. Backward navigation is critical. If you make the wrong choice, perhaps because your finger didn't touch the correct place on the screen, going back must be easy. This can be achieved by taking care to insure that the browser back button will always work, OR always having a reverse navigation element on every page.
