In her #SAG2023 keynote "Don't Hit the Iceberg", Diana Montalion reflects on the evolution from traditional software development to complex information systems involving interdependent services and data platforms. She introduces the Iceberg model from systems thinking, which highlights the importance of underlying mental models that influence our approaches to software architecture. Montalion argues that true digital transformation requires a shift from linear to systems thinking, stressing that merely scaling current methods is inadequate for addressing the challenges of modern systems architecture.
