Building a desktop application begins by selecting an appropriate platform approach: native options (Windows/macOS/Linux), cross-platform frameworks, and the distribution strategy. A clearly defined MVP and an initial prototype aid in validating workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, reliability, update management, and packaging take center stage. Proper handling of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily use, while an update system and crash reporting streamline ongoing maintenance.
