Designing Event-Driven Systems with EventStorming and ADRs

Building modern software requires clear alignment between business goals and technical architecture. Without a structured way to model domains and document decisions, development teams quickly lose cohesion.\n\nThis text-based course guides you through the foundational concepts of event-driven design, Domain-Driven Design (DDD), and collaborative modeling. You will learn how to map domain events and maintain a clear history of your system's evolution using Architectural Decision Records (ADRs).\n\nWhat you'll learn:\n- Understand the core principles of Domain-Driven Design (DDD) and event-driven architecture\n- Learn the mechanics of EventStorming to discover domain events, commands, and aggregates\n- Apply Behavior-Driven Development (BDD) concepts to bridge the gap between business rules and code\n- Write clear, version-controlled Architectural Decision Records (ADRs) using lightweight markdown formats\n- Structure collaborative planning sessions that bring technical and non-technical stakeholders together\n- Practice modeling complex business processes through structured written exercises\n\nThe course starts with essential terminology and the philosophy behind collaborative design. You will then progress through the step-by-step process of mapping domains, defining system boundaries, and establishing a sustainable documentation workflow that keeps your architecture transparent and maintainable.\n\nThis course is designed for aspiring software architects, developers, and product managers who are new to event-driven design and want to improve their planning workflows. No prior experience with DDD or system architecture is required.\n\nStart reading today to build a solid foundation in collaborative system design and architectural documentation.
