This document discusses how planning and responding to change were balanced on an Antarctic cruise. While extensive planning is needed for safety and regulations, crews must also be flexible due to the remote, unpredictable environment. Lessons included continuing to plan but having adaptable plans, setting clear expectations, keeping goals while adjusting approaches, and changing goals if needed. Empathy is also key when plans change, as it is difficult but important that all understand changes. The takeaway is that both planning and responding to change are important to address unpredictable circumstances.
