Most of us have been taught that analysis and reductionism is the way to deal with complexity, breaking the problem up into small manageable parts and treat them in isolation. Systems thinking puts a totally different spin on this, claiming that instead holism and synthesis is needed to fully understand a system, especially in order to get a grasp of the emergent behaviour that are not explainable based on the parts alone. In this talk I will take a brief look at these two paradigms and investigate how holism can provide important insights and knowledge to handle the complexity in domains that DDD is often argued to be the tool of choice for. We will take a look at why reductionism is dominating in the natural sciences, while social sciences is mostly explained using holism and see what these professions can teach us about how to approach software as part of a socio-technical system.

Trond is an IT architect and aspiring sociotechnical systems designer from the consulting firm Scienta.no and has many years experience with large, complex, and business critical systems, primarily as a developer and architect on middleware and backend applications. His main interests are service-orientation, domain-driven design, event driven architectures, and sociotechnical systems, working in industries like telecom, media, TV, and public sector. Mantra: Great products emerge from collaborative design.
