System analysis with Unistep

Unistep for system analysis with drill down

A system has a structure, some components. Each of the components may have components too. A process involving a system may be show how it goes inside a component for more details. There may be more levels of detail. You decide what is the depth level you want to show.

Here you find an example of  this kind of diagrams. You can show dynamically how control goes from the main processes to the sub processes (drill down), as system decomposition. You can show a high level view, or "drill down" in the details of contained structures.

System analysis  -  systems presentation
Main system. Arrow indicates the component (X2) that has a structure.		Drill down to level 1 (component X2).Arrow indicates the component (X22)		Drill down to level 2, component X22 structure

System analysis - processes in main system and its components
Main process		Process in component X2		Process in component X22
System analysis- follow main process in drill down inside component / follow drill up
In main system, step before drill down to component X2		In component X2, after drill down from main system (X)		In component X2, before drill down to component X22
In component X22, after drill down from component X2		In component X22, prepare return (drill up) to component X2		In component X2, after drill up from component X22
System X2, return to main stream		Main stream - return from X2		Main process continues
