Business models exist at the interface of strategy and operations management. This book identifies the role of business models within the context of how organizations seek to generate sustainable growth in earnings. Unlike other books on business models - which tend to focus on specific models or stem from the world of e-business and information management - this book enables readers to understand the importance of business models within the frameworks provided by competitive strategy. This reflects that strategic positioning has to be supported by an under-pinning business model that legitimises the strategy and facilitates its realization. For example, the 'cost leadership' strategy will need to be supported by a business model that enables this low cost positioning to be realised. In bringing a rounded understanding of business models from a strategic perspective, this book provides essential reading for advanced students of strategic management and operations management. For those newly developing courses on business models, the book will of course be a core textbook.About the Author: Colin Turner is Head of the Department of Business at the School of Management and Languages at Heriot-Watt University, UK Linda McGilvray is Deputy Director of the Masters in Strategic Project Management and Teaching Fellow at the School of Management and Languages at Heriot-Watt University, UK
