Residues: Time, Change and Uncertainty in Software Architecture

by Barry O’Reilly

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 modeling that uses applied complexity science to make managing uncertainty a fundamental part of the design process.
