Commonly Used Methodologies by Software Architects

Domain-Driven Design (DDD) is a software development methodology that addresses complexity by modeling the core business domain and building software systems around that model. It emphasizes continuous collaboration between domain experts and development teams, using a Ubiquitous Language as the foundation for communication. Through strategic design and tactical design, DDD manages complexity and ensures software can adapt flexibly to business changes.

Event Modeling is a structured approach for designing and building complex software systems by identifying and documenting key events and their relationships within a business domain. It helps teams understand business processes, define system boundaries, and guide technical implementation, emphasizing a business-centric, event-driven perspective to describe system behavior. It is suitable for distributed systems, microservice architectures, or domain-driven design projects requiring clear alignment between business logic and data flow.

Event Storming is a collaborative modeling method that visualizes domain events in business processes to help teams quickly understand complex systems, identify key issues, and design solutions. It emphasizes cross-functional participation, using tools like sticky notes on large walls to build event flows, fostering communication and consensus.
