Wire-frames are a critical tool in conveying your idea for an app, system or platform. It really allows you to get the nuance of your ideas across to those who will transform it into reality.
When your team only has text to follow it’s still open to interpretation how it will look, if the design and scoping is done prior to UI’s being created then they need to be re-scoped to address the changes that are introduced to their interpretation. With wireframes, you have the ability to visualise how things will look and work and provide a much clearer picture.
You can start with pencil and paper or a pen if you’re feeling more confident. If you’re comfortable with software to open up any number of available tools and start getting your ideas visualised and brought to life.
