Desktop application development begins with selecting the right platform approach: native (Windows/macOS/Linux), cross-platform frameworks, and the distribution method. A clearly defined MVP and an early prototype help validate workflows, performance requirements, and the overall UX on real hardware.

As the product matures, stability, updates, and packaging become essential. Careful management of file systems, permissions, offline mode, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains reliable in daily use, while an update mechanism and crash reporting simplify long-term support.
