Amundsen's announces the most remarkable change in plans when they are beyond recall.
Six months before Amundsen and his team were to leave for the North Pole, the explorers Cook and Peary both returned from Greenland claiming the North Pole. At that moment Amundsen's plans were in ruins. Funds had dried up and he would have been left with ruinous debts that would have ended his life as an explorer. Telling no one but his brother Leon and the Captain of their ship the Fram, Amundsen changes the expedition's destination and lets no one else know till they are beyond recall. If his plans had became known he might have been jailed. Witness this most remarkable of change initiatives as the explorer extraordinaire announces a "minor detour" to his team. This is a moment with many parallels in Organizational Learning and Development.
