Teams take time to form but once they do their trust can be almost instinctive.
In alpine climbing if two people are walking a ridge tied together with thousands of feet to drop, it may happen that one of them missteps and falls off one side. When this happens it is his partner’s job to immediately jump off the other side. This allows the rope to pull tight, balances the weight and prevents both of them from falling off the mountain. If the partner delays his jump then both are likely doomed.
Teamwork at its highest level becomes almost automatic no matter how tough the challenge.
When you think about your teammates and your level of teamwork you might stick this image of the alpine climber in your head and assess accordingly.
