Explain a Team-Owned System Architecture

# Explain a Team-Owned System Architecture Explain the business logic and technical architecture of a system your team owned, without exposing confidential employer information. ### Constraints & Assumptions - Use neutral domain labels where details are private. - Connect architecture choices to business rules and failure modes. - Make your own contribution clear without claiming ownership of the whole organization. ### Clarifying Questions to Ask - Who uses the system and what invariant matters most? - Where is the source of truth? - Which dependency or scale dimension shaped the design? ```hint Follow one transaction Trace a representative request or event from entry through state changes and observable outcome. ``` ### What a Strong Answer Covers - Business purpose, actors, and core invariants. - Major components, data ownership, interfaces, and flow. - Consistency, failure handling, security, observability, and scale. - Your contribution and one trade-off you would revisit. ### Follow-up Questions 1. How would the architecture handle ten times the volume? 2. Which component could be removed if requirements became simpler?
