Project planning application for Windows NT/2000/XP/Vista/Win7. A separate version is also available for a range of PDAs. Create a project plan by entering tasks and resources, add holiday information and create dependencies between tasks. Plan will calculate the entire project schedule taking into consideration dependencies and holiday information. Includes display of Gantt chart and critical path calculation. The program also can be used as an inexpensive Microsoft Project file viewer, since it can read MPP, MPD, MPX and XML files. Note, however, that Plan isn't simply a Microsoft Project viewer, since it also can update and recalculate projects and if necessary write them back in Microsoft format. Use Plan for Windows stand-alone or use it in conjunction with Pocket Plan on a Pocket/Handheld PC/Nokia Communicator. This option allows you to create project plans on your PC and then transfer the data to your PDA where you can continue to work on your plan.
