Building a desktop application begins by selecting an appropriate platform strategy: native for Windows/macOS/Linux, cross-platform tools, and the chosen distribution approach. Defining a solid MVP and an early prototype helps validate workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures daily reliability, while an update system and crash reporting streamline long-term maintenance.
