Designing top-level system architecture requires breaking down core modules, documenting key technical decisions, and mapping integration points. This process defines module responsibilities and records the rationale behind critical architectural choices.

Creating a module breakdown requires existing documentation for your technology stack and Product Requirements Document (PRD). These inputs allow the architecture design process to identify core modules like User Authentication or Order Processing and outline their responsibilities.

System architecture design handles integration points by explicitly mapping out how different internal modules and external services connect. This ensures all data flows and service interactions are clearly defined within the high-level technical architecture.

No, this module design approach requires a finalized technology stack and existing PRD documentation. It is specifically built to define top-level system architecture and module breakdown only after the foundational technology decisions have been made.

The best way to document critical technical decisions during system design is to record the architectural choices made, the alternatives considered, and their underlying rationale. This ensures all module definitions and integration points have clear justification.
