This chapter describes how to specify in detail the procedures and flows that will allow users to navigate through the system. Procedure interaction is what allows procedures to communicate with one another. This includes client-to-client and client-to-server procedure communication.
The GUI, procedure interaction, and procedure logic are best designed in parallel. Procedure interaction and layouts may then be refined, often by prototyping. When the initial design is stable, detailed procedure logic can be completed, and the flows and layouts can be finalized.
Together, the procedure interaction, layout design, and logic will yield a completed navigation diagram, fully detailed displays, and action diagrams that are the basis for generating a complete system.
