You may notice that Word is easier to work with than Excel. The reason for this is that there are often several sheets of information that you have to edit with Excel. When you are trying to work with a Word document then you do not have to worry about doing a lot of work and you can focus on getting the structure set up correctly.
Using the example of a work breakdown structure template is a good way to get your data into the format that you need. Of course, if you want you can always look at Microsoft Word or Excel, but that will take a lot longer to download and you will be making mistakes in the process.
