Episode notes
Visualize Systems As Graphs
- Graphs map components and connections so you can reason about complex systems visually.
- Diagrams let you convey architecture faster and to broader audiences than text alone.
Begin With Business Use Cases
- Start assessments from business cases and use cases, not implementation details.
- Decompose downward only after you understand inputs, outputs, users, and value.
Interview The Right People First
- Identify and interview subject-matter experts across roles to extract sparse documentation.
- Collect contacts from product owners down to operators to fill knowledge gaps.
