The Built Environment industry is moving through the largest transition of leadership in history - senior leaders are passing the baton to emerging leaders from GenX and Millennial ranks. These generations are the ones to engage in industry reinvention. With this transition comes new perspectives, new values, and a new vision for the future. Traditional definitions of leadership are being challenged and new definitions are being articulated. At the Leadership Summit on the Business of Design - Redefining Leadership for the Future, we wrestled with new mindsets, new themes and new language around this critical topic.
