This handbook began as an idea of sharing experiences as a professional practitioner logistician in the military, humanitarian and business operations fields over the years, and then subsequently as an academic teaching the disciplines. The handbook is intended as a practical knowledge and problem solving guide that can be used by practitioners, or integrated into academic or vocational learning and training programmes. The comparison of logistics and supply principles in business, military and humanitarian operations has not been addressed so far and this handbook is intended as the footprint from which further development in the field may take place.
