Wonderful insight and article a la Harvard Business School. Upshot: Portholes are still potholes at firms such as GM and Buick. What's needed? A new legion of managers that are really "founder-executives" in the mold of Sumner Redstone or Warren Buffett and a new cadre of best practices and systems replacing the infrastructure that's failed. GM is trying to sit on a collapsible camp chair with one broken leg. Get people who know how to create brands people want rather than managers who take what others started and attempt to make it their own.
