One of the great advantages to working in Windows with Office 97 is having the ability to create documents that use material from different applications. For example, a proposal to a client might contain material from Word, Excel, and Project. The proposal might begin with a letter of introduction, followed by answers to the bid request, and include documents containing project specifications, worksheets containing budget and resource items, charts showing costs and resource loading, as well as Gantt or Pert charts showing project management.
