One of the reasons why Excel is often used as a work breakdown structure template is because it is very straightforward to use. Another advantage of Excel is that you can enter the data into the spreadsheet using a simple keyboard shortcut. If you are working on a project that requires you to input a lot of data then you will want to make sure that you use Excel.
It is important that you do not make the mistake of assuming that all examples are the same. You should only use Excel as an example when you are looking at examples that are going to be used. There are a few Excel examples on the internet but most of them are for example only and so will be very short and easy to navigate through.
