Instead of guarding prototypes, build a library of high-fidelity, interactive demos and give sales and customer success teams free reign to show them to customers. This democratizes the feedback process, accelerates validation, and eliminates the engineering burden of creating one-off sales demos.

Users won't permanently reject a rough product if you respond to their feedback and ship improvements almost immediately. This rapid iteration turns initial frustration into loyalty. Slowness, not product roughness, is the real danger that causes users to lose interest.

The team no longer relies solely on PRDs and design docs. Product managers are now required to build a functional prototype as a core part of the development cycle, ensuring ideas are validated with a working model early on.

Shift the definition of "done" from "code checked in" to "logged in as the user and verified the feature works as intended." This simple directive forces engineers to engage with the product from a user's perspective, fostering ownership and higher quality work.

Voice of the customer research is often insufficient. Adopt iterative innovation by quickly creating and demoing cheap prototypes—even computer simulations or animated concepts—to get constant, early feedback. This validates ideas in real-time.

Traditional multi-page strategy documents often stagnate under the weight of comments and revisions. A product leader can accelerate team alignment and decision-making by creating a simple prototype that visually conveys core principles and a North Star direction, even if it's not production-ready.

For core product changes, Granola eschews quantitative A/B testing in favor of qualitative gut feel from intensive internal use. By building prototypes and having the entire team use them in their own chaotic workdays, decisions are made based on collective intuition about what *feels* better.

The V0 team dogfoods their own AI prototyping tool to define and communicate new features internally. Instead of writing specification documents, PMs build and share working prototypes. This provides immediate clarity and sparks more effective, tangible feedback from the entire team.

Anthropic has flipped the traditional development process. Instead of debating quality at the mock or discussion stage, they push teams to build a working version first. Quality decisions are then made based on hands-on usage of the live product, which provides much richer and more accurate feedback.
