Planet RoadmapBuilding the wrong thing is the most expensive mistake a product team can make. Weeks or months of engineering effort vanish when a feature launches to silence. The good news is that most ideas can be validated—or invalidated—before a single line of code is written. Validation is not about predicting the future; it is about reducing uncertainty to a manageable level.
Start with the Problem, Not the Solution
Before you validate an idea, make sure you are validating the right thing. Write down the problem you believe exists, who experiences it, and how they cope with it today. If you cannot clearly articulate the problem, the idea is not ready for validation—it needs more discovery.
Talk to at least five potential users and ask them about the problem without mentioning your proposed solution. If they do not recognize the problem or consider it minor, you have your answer early and cheaply.
Lightweight Validation Techniques
You do not need a fully functional prototype to test demand. Several low-effort methods can give you signal quickly.
- Fake door tests: Add a button or menu item for the feature and measure how many users click it.
- Landing page tests: Create a simple page describing the feature and track sign-up interest.
- Concierge MVP: Manually deliver the value the feature would provide and see if customers find it useful.
- Survey and interview: Ask existing users to rank the proposed feature against other options.
Using Feature Requests as Validation Data
If you already collect feature requests—through a tool like Planet Roadmap or a shared spreadsheet—you are sitting on a goldmine of validation data. Look at how many unique customers have requested something similar, how recently requests came in, and whether they come from your most valuable segments.
Quantifying demand from real users is far more reliable than hypothetical survey responses. When dozens of customers independently describe the same pain point, you can move forward with much higher confidence.
When to Move Forward
No validation method gives you certainty. The goal is to gather enough evidence that the risk of building is justified by the potential reward. A good rule of thumb: if you can find at least ten users who say they would change their behavior because of this feature, it is worth prototyping.
Document your validation findings alongside your roadmap so the team understands why each initiative earned its spot. This transparency builds trust with engineering and design partners who want to know their effort will matter.
