Leveraging the Black Box Decomposition • How do we go from the top down? • Is decomposition unique? • Must preserve all observables during decomposition and aggregation • Inputs and outputs • Input/output sequences • Number and conditions for exits • Performance

Aggregation • Often start with too much detail • Enhance understanding / see the “big picture” • Encapsulate complex logic into

larger building blocks (information hiding)

Partitioning the Integrated Behavior The integrated behavior reflects the three externals plus our system. We need to partition this and decompose the behavioral system context. 1. Close all open windows other than the project explorer

2. Select Function in the explorer panel 3. Select “Geospatial Library Context Function – Level 2” and open an activity diagram from the Views ribbon 4. In the explorer, select “_Perform System Context Functions” and open an activity diagram 5. Dock the system context to the left side of the screen and level 2 to the right
