To succeed in the face of disruptive competition, companies will need to harness the power of a wide range of partners who can bring different skills, experience, capacity, and their own networks to the task. With the advent of new technologies, rapidly changing customer needs, and emerging competitors, companies across more and more industries are seeing their time-honored ways of making money under threat. In this book, Arnoud De Meyer and Peter J. Williamson explain how business can meet these challenges by building a large and dynamic ecosystem of partners that reinforce, strengthen, and encourage innovation in the face of ongoing disruption. While traditional companies know how to assemble and manage supply chains, leading the development of a vibrant ecosystem requires a different set of capabilities. Ecosystem Edge illustrates how executives need to leave notions of command and control behind in favor of strategies that will attract partners, stimulate learning, and promote the overall health of the network. To understand the practical steps executives can take to achieve this, the authors focus on eight core examples that cross industries and continents: Alibaba Group, Amazon.com, ARM, athenahealth, Dassault Systèmes S.E., The Guardian, Rolls-Royce, and Thomson Reuters. By following the principles outlined in this book, leaders can learn how to unlock rapid innovation, tap into new and original sources of value, and practice organizational flexibility. As a result, companies can gain the ecosystem edge, a key advantage in responding to the challenges of disruption that business sees all around it today.

Un nouveau paradigme architectural ?!

Nos modes de constructions actuels dits « fixes », devenus pour le moins obsolescents, cherchent des réponses émanant de l’économie circulaire. Cette myopie actuelle de la notion de déchet semble alors détrôner tout le principe de démontabilité. Durabilité, flexibilité, désassemblage, adaptabilité, déconstruction, réversibilité… sont tant de termes qui doivent s’imposer à notre nouvelle culture de la conception et construction dite « cradle to cradle ». Traversant les échelles, du plus fixe (structure, site) au plus flexible (spatialité, enveloppe), le bâtiment se résume alors par une superposition de strates indépendantes les unes des autres. En bout de chaîne, le cycle de vie du bâtiment se referme ; les matériaux devenus alors source directe de réemploi : ablation de la démolition en résulte.

L’objectif de ce travail est de sensibiliser et d’informer les architectes et autres acteurs de la construction des opportunités qu’offrent de telles pratiques. Une approche systémique qui semble soutenir de grands concepts architecturaux dépassant la théorie vers une pratique, encore qualifiée de science jeune mais illustrant pour autant des résultats prometteurs. Additionnels au cycle de vie fermé, comment quantifier cette approche circulaire, sur quels critères s’appuyer ? A new architectural paradigm ?!

Our current so-called "fixed" modes of construction, which have become obsolete to say the least, are looking for answers emanating from the circular economy. This current short-sightedness of the notion of waste seems to dethrone the whole principle of demountability. Durability, flexibility, disassembly, adaptability, deconstruction, reversibility... are so many terms that must be imposed on our new culture of design and construction known as "cradle to cradle". Crossing the scales, from the most fixed (structure, site) to the most flexible (spatiality, envelope), the building is then summed up by a superimposition of layers independent of each other. At the end of the chain, the life cycle of the building closes; the materials then become a direct source of reuse: resulting in the removal of the demolition. 

The aim of this work is to raise awareness and inform architects and other construction actors of the opportunities offered by such practices. A systemic approach that seems to support great architectural concepts that go beyond theory towards a practice, still qualified as a young science but nevertheless illustrating promising results. In addition to the closed life cycle, how can this circular approach be quantified, which criteria should be used ?
