Desktop application development begins with selecting an appropriate platform approach: native (Windows/macOS/Linux), cross-platform frameworks, and the distribution method. A solid MVP and an early prototype help verify workflows, performance needs, and the overall UX on real devices.

As the product evolves, reliability, updates, and packaging become essential. Careful management of file systems, permissions, offline support, and integrations (device APIs, peripherals, enterprise auth) ensures the app remains dependable in daily use, while an update mechanism and crash reporting facilitate long-term maintenance.
