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 prototype help validate workflows, performance requirements, and the overall UX on real devices.

As the product progresses, reliability, updates, and packaging become key. Thoughtful 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 mechanism and crash reporting streamline long-term support.
