Building desktop software begins by selecting an appropriate platform strategy: native targets for Windows/macOS/Linux, cross-platform frameworks, and the distribution model. A clear MVP and an initial prototype help confirm 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 functionality, and integrations (device APIs, peripherals, enterprise authentication) ensures daily reliability, while an update system and crash reporting streamline long-term maintenance.
