Building desktop software begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform tools, and the distribution plan. A clear MVP and an early 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. Managing file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures day-to-day reliability, while an update system and crash analytics ease ongoing maintenance.
