As a leader, your role is to ensure that the team building activity runs smoothly and effectively. You should prepare the materials, equipment, and instructions beforehand and send a brief or agenda to your team members. At the start of the activity, explain the rules, objectives, and expectations in detail. During the activity, monitor the progress and performance of your team members and provide guidance or feedback as needed. At the end of the activity, debrief with your team members and ask them to share their feelings, thoughts, and learnings. Highlight their strengths, weaknesses, and areas of improvement. Finally, link the activity to your team's goals, values, and culture.
