In software architecture, it is important to know why a team has selected a specific architectural style, pattern, or technology. Clear communication of such decisions is crucial, and one of the best means to capture, communicate, and understand these decisions is through Architecture Decision Records (ADRs). This session will emphasize ADRs as an instrument that enables unambiguous communication among architectural stakeholders. Using real-world examples, we’ll explain the fundamental principles of ADRs, highlighting how they encapsulate the rationale, context, and consequences of architectural decisions. We will also cover best practices for authoring, maintaining, and evolving ADRs throughout the project lifecycle, from initiation to implementation. Regardless of whether you're an architect or a developer new to the space, with this session, you shall be well equipped with the tools to articulate architecture decisions using ADRs. Get familiar with the architectural maze so you can manage it with confidence and clarity, and be prepared to respond to the all-important question of why — now, tomorrow, and in the future.
