It's possible that using high quality templates in your project to give it visual interest might make your project more "engaging" for your stakeholders, giving you a competitive advantage. Templates can raise the perceived professionalism of your project: The same way that a suit might make you appear more professional when going on a job interview, the use of project templates can make your project appear more professional.
There are so many templates. You can write a simple letter. Or make a proposal for your work. The graphics are great and so easy to insert. With options like text boxes and the ability to add photos, everyone can turn out professional looking documents using Microsoft Word templates.
