Desktop app development begins by selecting an appropriate platform strategy: native (Windows/macOS/Linux), cross-platform frameworks, and the distribution approach. A clearly defined MVP and an early prototype help verify workflows, performance requirements, and the overall user experience on real hardware.

As the product evolves, stability, updates, and packaging take center stage. Careful management of file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains dependable in daily use, while a robust update system and crash reporting streamline long-term support.
