This talk presents the design sprint, a 4-day process for structuring innovation while accounting for user, business and technology needs. Born in Google and based on design thinking, it relies on a tight coupling between an idea and the data that allow to verify or discard it, ensuring that a product does at the same time match the business needs of the company and the needs of the final user. The advantages of this approach include a quick validation of new ideas before committing to a strategic project, the alignment of different stakeholders on the objectives and challenges to be faced, a structuring of creative thinking through visual representation, and an iterative verification of actionable outcomes.
