Introduction to Wireframing
Wireframing is a useful part of the design process. Throughout a website or mobile app project, you will have a lot of ideas and the best way to sort through those ideas is to brainstorm. Wireframes are a visual artifact of brainstorming, and the goal is to make them with minimal effort, as to encourage ideation. Whether you're a designer or not, wireframing is an important skill to have in your toolkit. It's beneficial for product managers, marketers, or anyone else with ideas for a website or mobile app. Wireframes are a valuable tool for visualizing user experiences, iterating on ideas, and sharing ideas with others.
