Desktop software development begins with selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform frameworks, and the distribution method. A clearly defined MVP and an initial prototype help validate workflows, performance requirements, and the overall UX 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 a robust update system and crash reporting facilitate ongoing maintenance.
