Desktop application development begins with selecting an appropriate platform strategy: native (Windows/macOS/Linux), cross‑platform frameworks, and the distribution approach. A clearly defined MVP and an early mockup help validate workflows, performance requirements, and the overall UX on real devices.

As the product evolves, stability, updates, and packaging take center stage. Careful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) makes the application dependable in everyday usage, while an update system and crash reporting ease long-term maintenance.
