Final answer:
Successful bridging requires fundamentally reformulating the problem followed by parties sharing information to understand their needs and inventing options that satisfy all.
Step-by-step explanation:
For successful bridging, what is required is a fundamental reformulation of the problem to shift focus from positions to interests and needs. This includes disclosing sufficient information to allow for an understanding of these interests and needs, which then facilitates the inventive process of creating options that satisfy all parties involved. In this way, the emphasis moves from confrontation to cooperative problem-solving, aligning efforts to realize a win-win situation. Examples of this can be seen in various social movements where unconnected organizations with similar goals band together to form a stronger coalition.
