One principle states that finding a solution requires understanding the problem. Implementing this principle requires identifying all groups and individuals involved in the problem, their relationships to each other, and the substance of the dispute. A second principle states that planning a strategy can facilitate reaching a solution; this involves developing a logical sequence of steps toward resolving the problem. A third principle, that human relationships are as important as technical data, can be implemented by applying ground rules for behavior and encouraging social interaction. A fourth principle -- providing necessary information -- requires establishing regular and predictable communication. The fifth principle advises that parties must agree on basic data. Finding mistakes in data and jointly agreeing on data corrections can facilitate cooperation in analyzing the general problem. Involving the parties in designing the mediation process and developing the solution is advocated in the sixth principle. The final principle states that lasting solutions are based on interests rather than positions. This involves guiding the parties to converse about their interests and their requirements for a satisfactory solution to the conflict.
