The Delphine Hanna lecture is a memorial to the contributions and vision of a great leader. It is a tribute time-out, a moment in time when we stop what we are doing to look back thankfully and to commemorate her life. It is also an opportune moment to consider what we have made of her legacy today and to look forward to the world that awaits future generations of professionals in our fi eld. Never before has there been such a need for clear 20/20 vision. As we look ahead to the year 2020, future scenarios for our fi eld are as diverse as our disciplinary bases. To sharpen our focus, we can draw upon scenario-planning methodologies used with some success in the business sector, where survival is premised upon accuracy.
