Definition
Problem decomposition is breaking down a complex problem into smaller, more manageable subproblems. This continues until each subproblem can be addressed independently.
Key Point
| Decomposition benefit | Practical effect |
|---|---|
| Reduced complexity | Smaller subproblems are easier to reason about |
| Parallel development | Different team members can build different modules |
| Reuse | Shared sub-solutions reused across system |
| Easier testing/debugging | Faults isolated within smaller units |
| Team collaboration | Clear component ownership |
| Project scalability | Large systems become manageable |
