"Challenging the prevailing myth of leadership as an individual activity, Ronnie Lessem makes a compelling and timely case for the "integrator" whose work emerges out of, and transforms the larger ecosystems of organization and society. Deeply resonant with the global challenges of the 21st century, the author has produced nothing short of a tour de force, and this work will rank alongside some of the greatest books on management wisdom."

"The Integrators is a fascinating book for managers and leaders within and outside organizations. The spectral management theory, developed by Ronnie Lessem and his colleagues, has a strong potential to help individuals uncover their strengths and qualities, making them better leaders and performers. It offers a new perspective to our understanding of the different ways and different stages of progress individuals follow on their road to leadership and beyond and the impact they make on organizations through learned use of their personal qualities. It is based on inspirational ideas, backed by rigorous academic research that has validated it and manifested its contribution to the scholarship of organizational management and leadership."

"As a facilitator of transformational change, in one of the world's largest technology companies, and as a recent graduate of a PhD program in Integral Development from a university co-founded in South Africa by a so called transformational leader par excellence, Nelson Mandela, I am well aware of the need to both incorporate and also transcend leadership, as we now know it, in a transnational and transcultural light. In this book Ronnie Lessem, like myself as an Iranian-German of dual Afro-European heritage, illustrates how the fusion of entrepreneurship, management and leadership leads to a fundamental transformation of each and all of such, a cultural and developmental integration so to speak. In particular due to the exponential spread of digitization in line with disruptive innovation there is a need not only to create new customer value, it requires new values in business, society and leadership to avoid a predator-capitalist downturn. As Vice President of Group Transformational Change at Deutsche Telekom Group I can see that Lessem’s work has significant bearing on our own activities, and can recommend it to those pursuing similar organizational transformations across different parts of the world."

"The Centre for Human Communication, first founded in Torquay in 1972, was a thrilling and magical place to be. Kevin Kingsland adapted the inspiration he received from Christopher Hills and many others in Centre House in London and combined it with an authentic yoga tradition. With a polymath mind he sought to test his understanding through the creation of a centre that would practise what it preached, not just study it. The Spectral Model that we all investigated with him, was used as a map that not only guided our investigations, created our organizations and helped us understand ourselves and our communication with each other, but also began to emerge as an archetypal "model of models". Ronnie Lessem, in this book, shares the result of his investigations of these same functions as they operate within the level of business organizations across the world and how the personalities of their creators and managers create truly successful communities, not just companies. Kingsland’s unique contribution was to inspire a flame of desire for the understanding of something that can be a real guiding hope for the future of humanity. It continues to burn brightly in Ronnie, myself and many others."
