The focus group technique is a form of qualitative research to help a team reach its goals and come to its decisions. In addition to asking what, where and when for making a group decision, it also seeks to establish the why and how of it. Within the focus group technique, the project manager heads a group decision. The individuals with the group then work towards solving problems and making decisions that will ultimately lead to the achievement of the goals of the group. In the case of project management, it would lead to a completed project.
During the focus group technique, the project manager will sometimes question all members of the working team what their opinions are on the matter at hand. It can be a sort of round-robin discussion after the opinions are drafted. From the opinions expressed, a common ground usually emerges. While it's impossible to get unanimous voting in most groups, members of the team often concede when strong points are made that are for the overall good of the group.
While the nominal group technique is more of a variation on a democratic process, the focus group technique involves more of an open-ended discussion to get to the final decision. Individuals participating in the focus group technique often feel heard and understood throughout the decision-making process.
