It is no exaggeration to say that the Olympic games, with 28 sports, 300+ events, dozens of venues, 10,500 athletes, over 7 million attending fans, 4.5 billion TV viewers, and over $5 billion in total revenue, add up to the most complex mega-sports event on earth. Everything about the Olympics is big. But the complexity is not a result of sheer size; it arises because success depends on myriad autonomous actors making good decisions, and on many different stakeholders seeing their (sometimes competing) expectations satisfied.
