The 2004 USA men’s olympic basketball team lost the dream … to be gold medalist in the 2004 olympic games.
For a lot of reasons.
Contrast that to the 2008 USA men’s olympic team. This team won the gold!

Coach K knew that ‘Teamwork makes the dream work’.
The 2008 team were put together long enough to allow time for the teammates to gel together as brothers. Three years before the games, they started the gelling process.
In contrast, the 2004 team were put together in a hurry … no gel time … on the court, five players played individually.
2004 and 2008 teams faced teams where players were like brothers … knew each other’s moves … on the court, five players played as one!
The whole is greater than the sum of its parts. Meaning, when parts are put together as a functioning one unit, the unit exhibits a unique quality far superior than its parts put together but nit a one whole functioning unit. This is Gestalt Thinking.
Anyway, teamwork made the dream work for the 2008 team. Out of five, one. And they had a collective ownership of the process and the outcome.
In SAFe, this teamwork makes the dream work is also true. Team members working together as one cohesive team … as brothers and sisters… with collective ownership of the process and outcome… the dream… a goal… a dream with a deadline.
