A3 system overview

Concise documenting of key system characteristics

Most high-tech systems are specified using a large number of documents that vary widely in content and form. It’s an approach that involves many risks: documentation becomes out-of-date, incomplete, inconsistent and increasingly difficult to access. As a result, product developers may operate and make design decisions on inadequate or outdated system representations.

In the A3 approach, architectural overviews are presented in A3-format as graphical and textual representations. The complete system is documented in terms of a limited set of system concepts. Furthermore, each concept is represented by multiple connected system views that demonstrate the interdependencies between the different views.
