Most products are often unusable for the first three months after launch due to unforeseen customer interactions, making it crucial to improve product usability early on.

Adopting a mindset of questioning every detail in your product can help identify issues and improve user experience, especially before launching.

Rapid prototyping and user testing are essential; focus on getting a functional prototype out quickly, using tools to create clickable mock-ups or writing throwaway code to test ideas with users, as building a fully functional product before testing can be an expensive mistake.

Usability testing with wireframes can reveal how users interact with your design before any code is written, saving time and resources.

It's important to gather user feedback early, even with a prototype, to ensure you're addressing real problems and providing value to your customers.

Iterative feedback cycles with a diverse range of users help reveal insights that improve product execution and user experience.

Write high-level integration tests instead of low-level unit tests. Simulate user interactions to ensure features work end-to-end before moving on to the next feature.

The convergence step involves testing prototypes with users to refine ideas and identify the winning components that resonate with current user needs.

It's beneficial to observe users interacting with the app to identify areas for improvement and enhance usability.
