What it is for
System Landscape (supplementary)
Why a specialized view helps
C4 views are zoom levels of one model; a dedicated tool keeps each level consistent with the next instead of redrawing boxes by hand.

What is visible: The courier landscape: Courier Tracking between its people and the three external systems, with the key along the bottom. The industrial plant's own landscape holds one system and draws the same picture as its context view, hence the other corpus. Nothing selected.
Why it matters: All systems of the organization appear in one view from the shared model, which shows where each system fits before zooming into any of them.
