Architecture documentation makes the reasoning behind a system’s decisions traceable, along with its building blocks and how they work together. arc42 provides a proven structure for this: twelve sections, from introduction and goals to quality requirements and architecture decisions, usable independently of technology or domain.
INNOQ also relies on arc42 in its own projects and uses it as the outline for its iSAQB® CPSA® Foundation Level training. Those who want to go further will find plenty of hands-on examples and concrete tips in the book arc42 by Example.
