Beginning with a suitable platform strategy is essential for desktop software: native options (Windows/macOS/Linux), cross‑platform tooling, and the distribution approach. A clearly defined MVP and an early mock‑up help validate workflows, performance requirements, and the overall UX on real machines.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful handling of file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) makes the app dependable in daily use, while an update mechanism and crash analytics streamline long‑term support.
