Based on the authors’ own volunteering and professional experiences, as well as interviews and informal discussion with more than 100 volunteers, this book is a hands-on guide to personal and professional growth in the field of project management. It is structured in three parts. Part I describes four ways volunteering can develop project leadership abilities. Part II focuses on leadership and adaptative skills, networking, and new skills gained by experimenting. Part III consolidates the learning and explains how to apply it at work. Each chapter ends with practical case studies, detailed interviews, key takeaways, and questions to reflect on.
