Explore a conference talk from Copenhagen Developers Festival that introduces residuality theory, a groundbreaking approach to software design for complex business systems. Learn how this revolutionary theory moves beyond traditional component and process modeling by incorporating applied complexity science to better handle uncertainty. Discover how software systems can be modeled as interconnected residues, providing a fresh perspective on managing and designing complex business environments. Through Barry O'Reilly's presentation, gain insights into this innovative framework that makes uncertainty management an integral part of the software design process rather than an afterthought.
