The purpose of this paper is to examine the effect about the team building which is based on the adventure program. This program operates on the individual directly, but it just still started in our country. In the first part of this paper I introduce the practiced program. Second, the effect of the program is verified. Though this program is one of the experiential leaning methods, the most characteristic point is verification of Full Value Commitment (engagement of consideration each other) and Challenge By Choice (Assurance that participant can decide method of participation) at start. These are useful to secure the safety of mind when the program is carried out. The setting of the aim is to make groups in which members can demonstrate 100% performance. The measurement of the effect is evaluated by the degree of achievement to their aim. Each team member answered the questionnaire, which was composed of particular abut setting of the goal at 3 occasions: pre intervention (pre), post intervention (post1), and two week before the target competition (post2). The results of an analysis of variance yield significant effects showing that this score of the members increased at postl and post2. In addition, the participant reported that improvement that is they can declare their opinions. This means the growth of the group was promoted. The process of team development was discussed for the future direction of facilitation strategy
