ECO.3:1 - Problem frame

Use this pattern when a need, available resource or possible combination is visible, but the parties’ current plans do not yet connect through a workable exchange. Start with the concrete contributions each party can provide and the result each seeks. The result is a proposed exchange that each can use, a conditional proposal with its remaining condition, or a specific incompatibility worth redirecting.

Use an existing satisfactory exchange directly. This method is useful when the missing contribution is discovering the terms or combination, rather than placing an ordinary order.
