Smart Share was a collaborative project with a co-worker who was under the gun with his research project. He had customer data and he had a vision, but marketing leadership couldn't understand his vision. So, off and on (over the course of a day and a half), I worked with him to create a clickable, Balsamiq prototype that allowed him to demonstrate what the customers were asking for and his initial vision for the product offering. 

It was an exercise in iterative brainstorming which allowed me to question his intentions (on behalf of his customers) and allowed him to better hone the user workflow and overall user experience.
