The fifth metric you should use is how much growth your team members have experienced as a result of their volunteering. To measure this, you can ask your team members to reflect on their own learning and development and receive feedback from each other. Additionally, you can acknowledge and reward them for their achievements, efforts, and improvement. This will foster a culture of learning and appreciation among your team and encourage them to pursue their goals and aspirations. With these five metrics, you can measure the success of a team when volunteering and enhance performance, satisfaction, impact, and growth. You can also use these metrics to set goals, plan actions, monitor progress, and evaluate results in order to make your volunteering experience more meaningful, enjoyable, and rewarding for yourself and your team.
