In this Medium article, Nikola Schou proposes improvements to the C4-model, a popular standard for software architecture diagrams. Schou suggests changing the four key abstractions from context, container, component, and code to system, component, sub-component, and deployment. The article also emphasizes the importance of cleaner and less cluttered diagrams with consistent notation for instant comprehension. While the C4-model is praised for its simplicity and logical structure, Schou notes the need for improvement, particularly in regard to using static views to understand system behavior. The proposed refinements can ultimately help the industry reach consensus and standardization in software architecture diagramming.
