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

As the product evolves, reliability, updates, and packaging take center stage. Diligent management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures daily reliability, while an update system and crash reporting ease ongoing maintenance.
