Human-centered design works best with cross-disciplinary teams. You could put three business designers to work on a new social enterprise, but if you throw a graphic designer, a journalist, or an industrial designer into the mix, you’re going to bring new modes of thinking to your team. It’s smart to have a hunch about what kind of talent your team will need—if you are designing a social enterprise, a business designer is probably a good bet—but you won’t get unexpected solutions with an expected team.
