Why you need prototypes and Powerpoints: this week Paul and Rich talk to Prashant Agarwal, the VP of Design at McKinsey Digital Labs. They talk about his career trajectory, from studying business to co-founding a startup to product management to design, and his current role at McKinsey, where he rethinks design challenges at scale. Paul and Rich also discuss content marketing, including this podcast and their fear of small talk at cocktail parties.
