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 verify workflows, performance requirements, and the overall UX on real machines.

As the product advances, stability, updates, and packaging become crucial. Careful management of file systems, permissions, offline functionality, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains dependable in daily use, while an update mechanism and crash reporting simplify long-term support.
