Desktop application development begins by selecting the appropriate platform approach: native for Windows/macOS/Linux, cross-platform tools, and the distribution model. A clearly defined MVP and an early prototype help verify workflows, performance requirements, and the overall user experience on real devices.

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