“Good follow-up is just as important as the meeting itself. The great master of follow-up was Alfred Sloan, the most effective business executive I have ever known. Sloan, who headed General Motors from the 1920s until the 1950s, spent most of his six working days a week in meetings—three days a week in formal committee meetings with a set membership, the other three days in ad hoc meetings with individual GM executives or with a small group of executives. At the beginning of a formal meeting, Sloan announced the meeting’s purpose. He then listened. He never took notes and he rarely spoke except to clarify a confusing point. At the end he summed up, thanked the participants, and left. Then he immediately wrote a short memo addressed to one attendee of the meeting. In that note, he summarized the discussion and its conclusions and spelled out any work assignment decided upon in the meeting (including a decision to hold another meeting on the subject or to study an issue). He specified the deadline and the executive who was to be accountable for the assignment. He sent a copy of the memo to everyone who’d been present at the meeting. It was through these memos—each a small masterpiece—that Sloan made himself into an outstandingly effective executive.”
