We present this brief reflection on key aspects of the 2030 Agenda for Sustainable Development and the implications of the worldwide focus on achieving the sustainable development goals as external observers of the evaluation endeavor around the world. We have conducted and participated in evaluations, but it is not our primary field of work and we are not engaged in the global community of evaluation specialists. However, we believe that the urgency of the challenges confronting the world today should inspire those influencing and shaping evaluation internationally to focus much more fiercely on the value of evaluation and its implications for leadership at all levels and in all fields of work. We propose that evaluation as practice should support and help inspire, value, and evaluate the type of leadership that the world needs now--dynamic and purposeful "living systems" leaders working toward large-scale, drastic change.
