How to treat Prototypes as Decision-Making ToolsDear Reader, You've probably heard the statement "With the friction of building nearing zero, it's even more important to have conviction about what to build and why" before. Truth is, this reduction in friction does not just apply to software in production. It also applies to the methods you use before that. The comparison I see to "pre-AI" ways of working is that teams, which were good at or limited to qualitative interviews, tried to reduce the uncertainty around each Discovery question with, you guessed it, interviews. I call these dogmatic defaults. A recent article by Ravi Mehta prompted (pun intended) me to revisit this idea - only this time with prototypes. "Prototyping is fun — and it’s easy to get pulled into crafting the perfect thing. It’s critical to remember that prototypes aren’t the deliverable; they’re a tool for making better and faster decisions." With everyone on your team (and in the boardroom) getting excited about prototyping with Lovable, V0 & Co., it's tempting to prototype every uncertainty you're trying to reduce. But that's dogmatic defaults all over again - just in a different color. We have to remember what prototypes can help you learn:
They're also fantastic alignment tools since a visual idea can replace lengthy written and spoken discussions. What prototypes can't tell you They won't get you to informed conviction about scaled adoption or willingness-to-pay. Not because the tools aren't good enough yet, but because those questions require a different category of evidence. Prototype reactions are attitudinal. Adoption and willingness-to-pay are behavioral. Someone saying "yeah, I'd use this" while clicking through your Lovable prototype in a 30-minute interview tells you almost nothing about whether they'll actually trade their time, attention, or money for it when the moment of truth arrives. Humans are notoriously bad at predicting their own future behavior. No prototype, no matter how fast you produced it or how polished it is, changes that. The underlying principle Every discovery question deserves a method that matches it. The temptation with any new tool is to let the hammer pick the nail. The question isn't "Should we prototype this?" The question is "What are we trying to decide, and what's the lightest, most honest way to get evidence for it?" Sometimes that's a prototype. Sometimes it's a fake door. Sometimes it's a pricing page with a pre-order button. Sometimes it's still a good old interview. The AI era doesn't make prototypes the answer to everything. It just makes them cheap enough to be the answer to more things than before. Which is why choosing when not to prototype is now a skill worth sharpening.

Product Practice #407 Your Goal Depends on Another Team — Now What? PUBLISHED May 7, 2026 READ ON HERBIG.CO Dear Reader, Your Key Result says to "Improve Conversion Rate by 7%," but you only control on-site search. You want to drive customer retention, but the marketing team is focused on new acquisition. Most teams respond in one of two ways: they water down the goal until it fits their scope (and lose the ambition), or they keep the big goal and quietly accept they can't move it. Both lead...
Product Practice #406 Why your Company's POV on OKRs matters more than Processes PUBLISHED Apr 30, 2026 READ ON HERBIG.CO Dear Reader, Before I talk with companies about OKR cadences, templates, or tools, I ask them: "What do you expect to change by using OKRs?" The answers take a bit of time. Not because they don't exist, but because OKRs have been treated as a solution without a problem to solve. OKRs haven't been treated as a product, but as a process without purpose. They've chosen a...
Product Practice #404 Linked Better Practices over Stacked Best Practices PUBLISHED Apr 16, 2026 READ ON HERBIG.CO Dear Reader, During a recent webinar, someone asked a question I had to think about a bit longer: "What do you do when your strategy is still early, and you're not sure if it's right?" The answer that popped into my head was based on an incredible piece of advice (or admission) I received from a former boss 10+ years ago: No one knows if their strategy is right in the beginning,...
