It's one of the six components of Shared Progress. It means partnerships based on trust and shared commitment to enable openness that determine the next steps based on connecting diverse insights.
Strong relationships build understanding, goodwill, and the possibility for shared horizons, even during discrepancies or broken promises. In a collaborative relationship, you feel willing and able to help someone spontaneously when asked because you understand their needs and priorities and know what will benefit them or promote their success without judgment.
