Architecture Diagramming Standards

C4 model mastery, sequence diagram design, system context mapping, and deployment view architecture. Move beyond boxes-and-arrows into diagrams that communicate the architecture independently — no presenter required.

Module 1: C4 Model Mastery

The C4 model was introduced in the 201 course. This module takes you from understanding to fluency — creating diagrams that are genuinely self-explanatory across all four zoom levels.

Module 2: Behavioral Diagrams

Structural diagrams show what exists. Behavioral diagrams show what happens. Sequence diagrams, data flow diagrams, and state diagrams capture the dynamic behavior that structural diagrams cannot.

Module 3: Deployment & Operational Views

Architecture diagrams that do not show how the system is deployed are architecture diagrams that stop being useful on launch day. Deployment views, network diagrams, and operational runbook diagrams bridge the gap between design and operations.
