In this lesson
identify the systems that many domains rely on and the coupling they create.
Planned topics
- Cross-domain systems: identity, billing, commerce core, data, integration.
- Their failures or changes affect many teams at once.
- Duplication appears when teams cannot wait for the shared system.
- Map dependencies with real call and data flows, not org charts.
Draft outline details
Demonstration
a dependency graph with five shared systems at the center and 20 teams around them, lines weighted by use.
