John Gattorna and Deborah Ellis are long-term collaborators on the design and management of enterprise supply chains. Dr John Gattorna has been one of the most influential voices in the development of the modern supply chain. His long-held vision of the supply chain as the central nervous system of an organisation and as a major source of competitive advantage if done well has inspired both supply chain professionals and CEOs. To support this vision, he has led the development of frameworks and tools to guide design using customers as the sole frame-of-reference, thus ensuring precise alignment between enterprise supply chains and the markets/customers they serve.In 2018 John was awarded the Council of Supply Chain Management (CSCMP) Distinguished Service Award for his contribution to the profession, and in the same year was inducted into the CSCMP Hall of Fame. Deborah Ellis has consulted with leading companies for over 20 years on logistics and supply chain strategy. Like John Gattorna, the emphasis of her work has been on developing tailored supply chains that generate market advantage. She has worked with him, and partnered with clients, to apply, refine and extend the frameworks and methodologies that simplify the supply chain task, while generating value for the customer and the business. Since 2017 they have together presented the Global Supply Chain Thought Leadership Retreat Series for senior supply chain executives in the Asia Pacific, South Africa and Europe. These by-invitation-only events have been very well received, and this book has evolved from the research and discussions associated with those events.
