The valley crossing exercise.

• Safe - Both the legs of the person have full support
• Half Risky – One leg in the air and the other leg has support
• Full risky - Both the legs are in the air without any support
• Half risky – One leg is in the air and the other leg has support
• Safe - Both the legs have full support

What this implies-

1. Figuring out what to do :

Role A = Role B = Role C : All roles are equal and there is no differenciation between the responsibilities of any two persons.
For all the 3 members, the task is designed to be - Easy, Lighter, Clear and Systematic 
All three are equally responsible in their contributions for the overall task completion.
2. Figuring out who should do :

Roles of all three members are similar but not same; and equivalent in terms of total effort & risk.
All 3 member Roles have equal distribution of 
Risky situations (1); 
Half risky situations (2); 
No risk situations (2)
All roles are designed for equally strong persons and there is no weaker or stronger requirement in any specific role.
Communication and feedback across the 3 members was instantaneous.
Interdependence among the 3 members was maximised and made crucial.
The roles are interlocking, with highest levels of interaction among the members, with instantaneous feedback being exchange and without any scope for social loafing.

3. Figuring out how to do :

All the 3  members are systematically trained for all the steps and, while crossing, they communicate and coordinate with each other through a various kinds of sounds and other signals.

4. Team Excellence :

Team excellence comes through proper designing of team tasks, correctly assigning team roles, and preparation and execution of the tasks. Thus, excellence is designed by the managers.
