This study examined how decision-making procedures can facilitate the positive attitudes necessary for cooperative relations in decision-making teams. We hypothesized that consideration of member input and members' influence on a decision affect their perceptions of procedural fairness and consequently, their commitment to the decision, attachment to the group, and trust in its leader. An experiment involving intact management teams supported these hypotheses and indicated that perceived fairness partially mediated the impact of procedures on commitment, attachment, and trust.
