Reading an architecture diagram with the C4 model
Reading an architecture diagram lets a PM check whether a proposal actually addresses the problem at hand. The lesson uses the C4 model to spot what a diagram shows, what it leaves out and where trust boundaries sit, then to turn each blind spot into a precise question before the sign-off meeting.
Lesson objective
By the end of this lesson, you will be able to read an architecture diagram at the context and container levels of the C4 model, spot users, external systems, containers, flows and trust boundaries, and turn its gray areas into questions for the team.
