Domain-Driven Design Europe 2022 http://dddeurope.com - https://twitter.com/ddd_eu - https://newsletter.dddeurope.com/ https://linkedin.com/company/domain-driven-design-europe Organised by Aardling (https://aardling.eu/) Residuality theory is a revolutionary new theory of software design that aims to make it easier to design software systems for complex business environments. Residuality theory models software systems as interconnected residues - an alternative to component and process modelling that uses applied complexity science to make managing uncertainty a fundamental part of the design process.
