It’s tough to find examples of successfully challenging the boss, even tougher to find stories of leaders who specifically ask to be challenged. The most common is a tale of Alfred P. Sloan at General Motors. During a meeting in which GM’s top management team was considering a weighty decision, Sloan closed the meeting by asking.” “Gentlemen, I take it we are all in complete agreement on the decision here?” Sloan then waited as each member of the assembled committee nodded in agreement. Sloan continued, “Then, I propose we postpone further discussion of this matter until our next meeting to give ourselves time to develop disagreement and perhaps gain some understanding of what this decision is about.”
