The Variety Calculus has profound implications for leaders, decision makers in any sector struggling to achieve clarity and agency in the challenging and complex world we face now and in the future. The Variety Calculus provides the means to tailor organisations, capabilities, or technologies to the nature of their operating circumstances, whether simple or complex. It puts into practice a different way of thinking and envisaging systems that will help understand situations, design solutions, and take decisions with confidence. Derived from cybernetics – the universal mechanisms through which all systems, social or technological, adapt and maintain viability in dynamic conditions - it provides a theoretical framework and practical tools and methods to generate effective agency even in the most challenging tasks. Cybernetic ideas have been uniquely developed into an accessible and comprehensive methodology that is applicable to all aspects of purposeful system design and allows professionals to navigate the complexity of the modern ‘Information Age’ world.
