First of all, cooperation is a conviction to think that:
1. We don't have all the answers to every question but even that:
2. Another person may have a better idea than me.
Such belief is the beginning of everything. If we think that no one can achieve as much as a team can achieve together - actual cooperation begins.
Such a belief must be supported by the actual belief that we want to jointly find a solution but also that we are in a state and ready, jointly take responsibility for failure if we fail to find it (or we cannot find it within the required time).
Actual, real cooperation begins with active listening together. Active listening is openness to other people's ideas as well as building own ideas based on his ideas and accepting the fact that another team member can creatively use my ideas. This requires refraining from selfish belief that "I know best" but even more that "my knowledge is at the team's disposal".
