Starting with choosing the right platform strategy for desktop software: native options (Windows/macOS/Linux), cross-platform frameworks, and the distribution model. A clearly defined MVP and an early prototype help confirm workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, stability, updates, and packaging become essential. Careful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains dependable in daily use, while an update mechanism and crash analytics streamline long-term maintenance.
