Strategic orthodoxy is rightly about focus, alignment, and tough choices. Trying to achieve incompatible goals can lead to tensions, contradictions, and loss of advantage. Yet, the rules of competition are changing. There is a select group of companies around the world that have managed to transcend conventional categories and contradictions to develop strategies that deliver competitive advantage and outstanding performance. We call these "Janus strategies", after the Roman god Janus who surveys two or more directions simultaneously. Based on in-depth case research and decades of development and advisory work with strategists this book outlines how these companies accomplished Janus strategies, while others failed to do so. "Janus Strategy is a gem of a book It explores one of the eternal challenges in the field of strategy - how to manage dual and often contradictory challenges. This superb book is full of fresh ideas and practical advice. It deserves to be widely read and be on the shelf of every senior executive crafting their organisation's strategy."Costas Markides, Professor of Strategy & Entrepreneurship, LBS. "Janus Strategy is a highly accessible and enjoyable practitioner's guide to ambidexterity: the ability to both explore and exploit in an advantaged manner. Illustrated by colorful case studies it argues that by deploying 6 principles, companies can not only trade off opposing considerations but achieve synergy between them, just as the Roman god Janus, was able to see in different directions simultaneously." Martin Reeves, Senior Partner and Managing Director at BCG. "I have known and worked with Loizos Heracleous for many years and executive colleagues and corporate students have found his work to be both inspirational and of practical value. I trust readers will find this book equally stimulating." Richard Hill, Director of Learning and Development at Rolls Royce (retired). "If you ever wondered how to pursue promising, though contradicting objectives this is a book for you. It's both an eye-opener and practical guide helping you to build your own Janus strategy. The stories from companies having done this before, makes it a great read. No doubt you will enjoy it as much as I did." Christian Stadler, Professor of Strategy at WBS. "Loizos is one of those very few academics who combines a joyful enthusiasm for business with rigorous research and analysis. Being able to handle ambiguity, to be able to think and chew gum, to be able to look and act in two different directions at the same time is a key skill of people who aspire to run large organizations, and is the reason why being a CEO can be such fun." Rupert Soames OBE, CEO, Serco. "Bringing together a fascinating mix of cases, examples and thinking from refreshingly different areas, Heracleous has created a book that is as intriguing and inspiring as it is pragmatic and timely." Marcus Alexander, Adjunct Professor of Strategy & Entrepreneurship at LBS. "Heracleous has provided a much-needed perspective on strategy in his book Janus Strategy. Often managers shy away from trying to resolve paradoxes and conflicts in their business. This book shows us how to welcome and be comfortable with them, and more importantly, how to use them to build competitive advantage." Pinar Ozcan, Professor of Entrepreneurship & Innovation, SBS, University of Oxford. "Heracleous inspires with a wonderful and rich collage of ideas drawn from Greek philosophers, Roman mythology, Nobel Laureates, and contemporary business leaders under the rubric of Janus Strategy." Michael Barrett, Professor of Information Systems and Innovation Studies, JBS, University of Cambridge." "Janus Strategy is a masterful presentation of the latest thinking about organization strategy written by one of the leading analysts and authorities on the subject."
