Senge's principle of building a shared vision involves creating a vision for the future of an organization through interaction and compromise between individual visions, rather than a leader dictating a singular vision. A shared vision fosters genuine commitment over mere compliance. For a vision to be shared, members must enroll in it voluntarily, as vision cannot be sold by the leader. When an organization has a shared vision created this way, it provides a driving force for change and learning as members are motivated by their shared goals.
