Desktop application development begins by selecting an appropriate platform strategy: native (Windows/macOS/Linux), cross-platform frameworks, and the deployment model. A clearly defined MVP and an initial prototype help validate workflows, performance requirements, and the overall UX on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline operation, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily use, while an update system and crash reporting streamline long-term maintenance.
