Divide Software Problem
A step in project assessment process is to break down your software problem into smaller parts. You can represent each part as a separate application or component.
Facilitate separation of concerns.
Are easier to work with.
Enable parallel development.
When assessing a component for reuse, consider whether the component is:
Reusable as is.
Reusable with slight variations.
Expected to be volatile.
If you have access to System Composer™, you can use that software to graphically represent software components as you decompose the software problem and design a software architecture. For more information, see Author Architecture Models (System Composer).
As part of the decomposition process, identify data and execution dependencies, such as ports, function-call interfaces, and parameters that require tuning and signal data that must be measured during program execution.
