A group is more than just a collection of individuals. It has several central, defining features:

• Common Purpose: Group members strive to achieve a shared goal.
• Interaction: Members communicate with one another. While this often happens face-to-face, it is not a mandatory characteristic, especially with the rise of virtual teams. The key is the interaction itself, not the medium.
• Mutual Influence: Members influence and are influenced by one another.
• Interdependence: Members rely on each other to achieve the common purpose.
• Formal vs. Informal Groups:
  • Formal groups (or task-oriented groups) are specifically formed to achieve a common purpose, such as solving a problem or completing a project.
  • Informal groups typically form for social and spontaneous reasons.

Within a group, individuals adopt various roles that contribute to its function. These roles can be divided into two main categories:

Task Roles:

These roles are focused on helping the group achieve its goals and complete its tasks. Examples include:

• Initiating: Proposing new ideas or procedures.
• Information/Opinion Seeking: Asking for facts or opinions to clarify issues.
• Consensus Seeking: Checking if the group is nearing a decision.
• Energizer: Stimulating the group to keep the discussion moving forward, especially when it becomes bogged down by frustration or gloom. The energizer keeps the group motivated.
• Factual Contributor: Providing relevant facts and data.
• Devil's Advocate: Challenging the group's assumptions to ensure ideas are well-tested.

Building/Maintenance Roles:

These roles are focused on maintaining positive relationships and a supportive group climate.

• Encouraging: Praising and supporting the contributions of others.
• Harmonizing: Mediating disagreements between members.
• Compromising: Offering to yield a point for the good of the group.

• Diversity among group members (in terms of background, experience, and perspective) is crucial to the success of groups.
• For a group to be truly successful, it must do more than just tolerate diversity; members should actively encourage and support diversity.
• A proactive and positive approach creates an inclusive environment where varied perspectives are valued, leading to better problem-solving and more innovative ideas.

• When to Use a Group: Groups are particularly effective for problem-solving when commitment to the final decision is important. The collaborative process helps ensure all members feel a sense of ownership over the solution and are more likely to support its implementation. Simple tasks or those requiring a quick decision are often better handled by individuals.
• Consensus: This is a method of reaching a final decision where all group members agree on the outcome through the process of discussion and debate. It is different from a majority vote or a compromise where some members may not be fully satisfied.
