The document discusses the interest-based approach (IBA) to problem solving and decision-making. IBA focuses on interests rather than positions, seeking to expand opportunities and satisfy multiple parties' interests with creative solutions. Key aspects of IBA include separating people from problems, unpacking interests, generating options, using objective criteria, and reaching consensus through behaviors that support collaborative decision-making. The document provides examples and an exercise to illustrate how IBA differs from and can be more effective than positional bargaining.
