Technology architecture - Concept
System landscape
The overall collection of systems an organisation uses and how they relate
What's it for?
Gives a whole-organisation view of the systems in use and how they relate to one another.
For example…
A system landscape diagram shows CRM, ERP, HR, data warehouse and integration platforms together so teams can see the whole technology estate
During a merger, architects map both companies' system landscapes to find duplicate applications and missing integrations
