Requirements
The technique has four requirements.
First, each member is given sufficient time to think about the task before entering the core group.
Second, the new member must make a preliminary solution presentation before hearing the core group's ideas.
Third, sufficient time is allocated to discuss the problem as each person is added.
Fourth, the final decision occurs only after the entire group is formed. These steps make it difficult for a member to "hide" in the group.
