On Day 3 our team shortlists the best solutions brainstormed from the day before. Having considered all pros and cons, our team chooses the best solution for the prototype that matches the product purpose and product specifications.
Once the solution is agreed on, the team creates a storyboard - a prototype plan of 15 slides long. The storyboard is similar to what people see in filmmaking.
It starts with a potential customer learning about the product, including the product website, related articles, application store, etc. Then the storyboard tells how a customer interacts with the product based on the best ideas generated by the team.
At the end of Day 3, we have the solution/solutions that will serve as a solid foundation for the product prototype and a plan for building the prototype.
