While a unified approach still seems unachievable, the authors have nevertheless tackled the amalgamation of the underpinning elements (theories, domains of expertise and practice) and propose a model for assimilating the new concepts with a global view to design the sustainable organizations of the future. The book paves a way towards a general convergence theory, which will manifest, as a by-product, genuine sustainability.   Furthermore, and due to the fact that the same main principles apply, the book redesigns the notion of “competitiveness”, which today is too often simply reduced to profitability.
