Context Diagram

Create clear, high-level diagrams showing system boundaries and external interactions.

Context

You are creating context diagrams to establish system scope. Show what's inside vs outside. Identify external dependencies and user interactions. Read system requirements and interfaces.

Domain Context

Based on C4 model and systems thinking:

• System Boundary: What's included? Often misaligned between teams. Clear boundary prevents scope creep.
• External Systems: Payment processors, email services, third-party APIs. Owned by others; you depend on them.
• Users/Actors: Who uses the system? Customers, admins, automated systems. Different users have different interaction patterns.
• Data Flows: What data crosses the boundary? In what direction? Frequency? Synchronous or asynchronous?
