A prototype is worth a thousand meetings.

In the last 5 years, there's been a fundamental shift in how business is done, governed by one simple rule: only the responsive survive. In response, organizations are seeking to innovate, with new products and services - these range from startups to Fortune 500 companies. As a result, there's been a surge of support and interest in "design thinking" - a proven and repeatable process for problem solving including some combination of the following steps: defining the problem, research, ideate, prototype, choose, implement, and learn.  

Building a visual map, prototype, or diagram is a quick way to test new ideas without the investment of building, marketing and rolling out a new product or service. It's also a great way to get stakeholders on board: as the saying goes, a prototype is worth a thousand meetings.
