DESCRIPTION
In this GOTO Book Club interview, Jacqui Read discusses with Barry O'Reilly his books "Residues: Time, Uncertainty, and Change in Software Architecture" and "The Architect's Paradox". He explains how uncertainty defines the architect's role and introduces residuality—a method where architects deliberately stress their conceptual models until they collapse, then optimize the resulting "residues" or leftovers to create more resilient systems.
Unlike traditional software engineering approaches, that try to eliminate uncertainty through rigid requirements, residuality embraces random stressors (even far-fetched scenarios like giant lizards) to uncover architectural fault lines.
O'Reilly argues that this playful yet mathematically sound approach produces more robust architectures than conventional methods, and his second book explores how inherited philosophical thinking often undermines software architecture's effectiveness in complex business contexts.
