If you want to save time on development.
Wireframing is a quick and effective way to identify usability issues early on in your design process. In simple words, wireframes are 2D skeletons of your product. We all know what wireframes are and how to use them. So, let's highlight the benefits of this ninja skill.
Wireframes allow you to map out the functionality of the product, catch problems early, and save time on revisions later. In other words, mapping out the functionality early will reduce the amount of back and forth that often comes with the development phase. Definitely, it is easier to rewrite the function in a wireframe, compared to the actual development phase.
Also, wireframing allows you the opportunity to?get to know your client better. You will start seeing patterns in behaviors and motivations the more time you spend with your client.
Wireframes push usability to the forefront and using them is a strong way to illustrate the layout and the functionality. And the most important thing is you don't need an artist for wireframes.
