When working on professional services bids, we're always looking for ways to demonstrate to the client what the future might be like if they were to decide to work with us. Sometimes it's about using words to tell a compelling story, but sometimes an image or even a mocked-up 'product' can do the job even better.
Picture it: this is a phrase that so many creative thinkers use when they're introducing their new project. The best ideas begin with a compelling image. In a single image lies a larger story, a whole series of suggestions, memories from the past, and gestures toward the future. Visual aids are indispensible tools for any innovator that help generate and motivate breakthrough change.
