Desktop application development begins with selecting the right platform approach: native (Windows/macOS/Linux), cross‑platform frameworks, and the distribution model. A clearly defined MVP and an early prototype help validate workflows, performance needs, and the overall UX on real devices.

As the product matures, stability, updates, and packaging become essential. Careful handling of file systems, permissions, offline mode, and integrations (device APIs, peripherals, enterprise auth) makes the app reliable in day‑to‑day use, while an update mechanism and crash reporting simplify long‑term support.
