Starting with the platform strategy: native ecosystems (Windows/macOS/Linux), cross‑platform tools, and how you will distribute the product. A clear MVP and an early prototype help verify workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file storage, permissions, offline operation, and integrations (device APIs, peripherals, enterprise authentication) ensures the app stays dependable in everyday use, while an update system and crash reporting ease ongoing maintenance.
