Episode notes
Balancing Precision and Practicality
- Software design, like construction, balances precision with practicality.
- Over-engineering everything increases costs and slows development without significantly improving core functionality.
Managing Coupling
- Coupling in software design is inevitable and connects different modules.
- Manage coupling effectively, instead of trying to eliminate it, to control system behavior and future changes.
Knowledge Exchange in Coupling
- Knowledge exchange between coupled modules, whether implicit or explicit, is a key aspect of coupling.
- Minimizing shared knowledge reduces cascading changes, while maximizing it increases them.
