Building desktop software begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform tools, and the deployment method. A clearly scoped MVP and an early prototype 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, access rights, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures daily usability, while an update system and crash analytics ease ongoing maintenance.
