This panel focuses on the application of Human Performance Improvement (HPI) and other approaches to the management of cultural change during transition – transition of the managing contractor, transition of a mission, and/or transition of a workforce. Change of this nature is one of the only certainties in the DOE complex today; the panel will discuss their challenges and experiences – successful and otherwise – driving change with the objective of yielding a strong safety culture on the other side of a transition. Topics will include respect for a historical legacy of performance, reinforcement of changed requirements and expectations, and blending cultures.
