Prototyping is crucial; instead of spending months on a project before showing it to anyone, build prototypes and share them throughout the design process to gather feedback early.

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.

Prototyping is an incredibly valuable tool, even if I personally haven't utilized it much. I tend to rush to build and ship my code, but I recognize that taking the time to prototype can lead to better outcomes.

If you're not prototyping and building to see what you want to build, I think you're doing it wrong. Prototyping is essential for effective product development.

Doing things that don't scale allows startups to experiment, fail fast, and quickly test assumptions before investing significant time in product development.

Testing low-fidelity prototypes with core super fans provides valuable feedback and can significantly reduce development time.

Common mistakes in prototyping include overbuilding and not engaging with users early enough to gather feedback.

It's crucial to engage with customers early on, as they can provide valuable feedback that helps you build a better product than if you just focus on perfecting the prototype first.

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.
