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

As the product matures, reliability, updates, and packaging become priorities. Careful handling of file systems, permissions, offline mode, and integrations (device APIs, peripherals, enterprise auth) makes the app dependable in daily use, while an update mechanism and crash reporting simplify long-term support.
