Beginning with selecting an appropriate platform approach is crucial for desktop software: native options (Windows/macOS/Linux), cross-platform frameworks, and how the app will be distributed. A clearly defined MVP and an early prototype help confirm workflows, performance needs, and the overall user experience on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline behavior, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily use, while an update mechanism and crash reporting ease long-term maintenance.
