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 confirm workflows, performance requirements, and the overall UX on real devices.

As the product evolves, stability, updates, and packaging become essential. Thoughtful management of file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures daily reliability, while an update system and crash reporting ease long-term maintenance.
