The C4 model is an easy to learn, developer friendly approach to software architecture diagramming. Good software architecture diagrams assist with communication inside/outside of software development/product teams, efficient onboarding of new staff, architecture reviews/evaluations, risk identification (e.g. risk-storming), threat modeling (e.g. STRIDE/LINDDUN), etc. The C4 model was created as a way to help software development teams describe and communicate software architecture, both during up-front design sessions and when retrospectively documenting an existing codebase.
