The benefits of planning with normative and heuristic approaches

The effectiveness of planning groups that used normative planning approaches and heuristics were investigated. The quality and innovation in plans developed using each planning approach were compared. Two studies were carried out in three organizations. In the first study, a ‘behavioral’ planning approach and a heuristic were used in a single organization. In the second study, a ‘systems’ planning approach and the heuristic were applied in two organizations. The field experiments demonstrated that the normative planning methods produced plans with superior quality and higher information levels. No differences in plan innovation were observed. Some guides for practice were derived from these findings.
