EventStorming As Applied Residuality Theory

Toward a Systems-Oriented Practice of Resilient Software Delivery

In the modern delivery of software systems, resilience is increasingly recognized as not just a runtime concern but a systemic property that emerges from how we model, design, develop, and evolve our systems. Two complementary frameworks help illuminate this broader view: Residuality Theory, which focuses on what persists in systems over time, and EventStorming, a collaborative modeling practice grounded in the temporal dynamics of domain behavior. When integrated, these approaches provide a powerful, systems-level perspective for improving understanding, alignment, and adaptability across the entire delivery lifecycle.
