You can use industry-standard structured analysis and design techniques and methodologies to model processes.

Various analysis and design methods developed over time to support the analysis of the events and processes of real-time systems.

For more information, see History of analysis and design methods for process modeling

System Architect supports several analysis and design techniques.

For more information, see Methods and techniques for process modeling

You can create and edit decomposition diagrams to supplement formalized structured analysis and design methodologies in a variety of ways.

For more information, see Modeling with decomposition diagrams

A variety of diagrams are available to model systems using the Structured System Analysis and Design Method (SSADM).
