Architecture Communication
Explain the same architecture to a CEO, an engineering manager and an engineer.
20 topics in this area.
Each topic is the unit content is filed against. Topics with nothing in them yet are shown too — they are the honest edge of the curriculum rather than a gap being hidden.
Architecture Communication
General material on communicating architecture.

Decision first, cost, risk, and what happens if we do nothing.
Presenting to Engineers
Mechanism, alternatives rejected, and what you are unsure about.
