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

As the product grows, stability, updates, and packaging take center stage. Careful handling of file systems, permissions, offline mode, and integrations (device APIs, peripherals, enterprise authentication) makes the app reliable in daily use, while an update mechanism and crash reporting simplify long-term support.
