1. Mental, or psychological, state of your team is important: you can put so much pressure on people before they crack. Brazil players didn’t become unqualified professionals overnight. They failed because they were overwhelmed by their country’s expectations, distorted sense of history, and the right to win considered divine. They were too emotionally charged, not in the proper state of mind to compete. So better keep calm, relaxed atmosphere in your team even before launch, or important deadline.
2. Manage customer expectations. Brazil were ramping them up unreasonably. Aggressive messages like the 6th[title] is coming, statements by their coach about two more steps to heaven massively backfired by creating an unhealthy emotional frenzy in the society, which in return influenced the players (see 1.)
3. Logic, organization is the key to successful execution. Germany are not a great team. But they are very well organized. They had a detailed game-plan where every team member knew his task and several different scenarios where prepared. They were able to adjust when the situation on the field changed to squeeze maximum advantage. Sounds simple? That’s because it is.
