The NextDesign Leadership Institute was founded in 2002 in New York by GK VanPatter and Elizabeth Pastor as an experiment in community innovation acceleration. Launched in parallel, the NextD Journal / ReRethinking Design leads strategic design journalism. You can have look at articles they’ve written, or check out their twitter page for updates.
This document by NextD (sorry I can’t embed it) explains the changing role of design really clearly by using consistent visualisations. I’m looking to them as a model for when I visualise different strategic design frameworks.
