Templates are a major time_saver: The most obvious benefit of using a template is that it's a major time_saver. You don't have to create everything from scratch because a lot of the complex work is done fore you. A template allows you to drop in the look you want and then customise according to your needs. This is significantly faster than starting from a blank canvas. Templates can give you a competitive advantage: When you manage projects and delivery it successfully, it's essentially competing with other project managers, departments or against another company.
Templates save you money: If you use a royalty_free template, it likely costs less than hiring someone to create a custom graphics package for you. You could easily spend hundreds (or possibly thousands) of pounds on a custom motion graphics opening, for example, whereas you can frequently purchase a royalty_free template for under £200. Of course, the royalty_free template isn't as unique as a totally custom template, but it definitely costs less, and you could always customize the royalty_free template to make it more unique for you.
