Teamwork is essential for effectiveness and efficiency in the workplace. It starts with assembling a team with a range of skills focused on common goals aligned with organizational objectives. When a team collaborates well, the whole becomes greater than the sum of its parts due to diverse perspectives and cooperation. While teams can fail due to lack of cooperation or leadership, the pros generally outweigh the cons, including a more creative and strategic problem-solving approach. Real-life examples where teamwork thrives include brainstorming meetings, group presentations, mentoring, and event planning.
