What matters in practice
- 01
Start with requirements and failure cost, not a preferred implementation.
- 02
Account for licensing, integration work, migration, and long-term maintenance.
- 03
Extend existing plugins when their architecture and license make that sustainable.
- 04
Build custom only with an owner, test strategy, documentation, and update plan.
