You might occasionally find it necessary to share information between project plans, especially when you're working with multiple projects or adapting information from an old, finished project to a new project you're beginning to plan. There are a variety of situations in which you might need to share information, as follows :
A task in one project might depend on the start or finish of a task in another project.
Task or resource information or specific fields might need to be copied or moved from one project to another.
Customized project elements, such as views, reports , or calendars, might need to be copied from one project to another.
With Microsoft Office Project 2003, you can easily exchange different types of information between project plans, enabling you not only to model your project appropriately, but also to increase your efficiency by decreasing duplicated entries or development.
