Andrew Harmel-Law's talk at GOTO Copenhagen explores how lightweight Architecture Decision Records (ADRs) and an architecture advice process can decentralize architectural decision-making. ADRs serve as an immutable changelog and learning resource, while a weekly architecture advice forum builds trust and transparency by making decisions visible to all. Key failure modes include lack of trust, fear of accountability, and top-down mental models that prevent power-sharing. Harmel-Law argues that deciding small and fast, then gathering feedback quickly, is essential to good architecture in modern, fast-moving systems.
