Difficulty: Intermediate

Evidence strength

Relevant metrics: Acquisition, Activation, Customer feedback, Email Sign ups

Validates: Feasibility, Viability, Desirability

How: Build a product that only solves one specific problem that your customers are having Ð typically a tool with one single feature.

Why: Building just a single feature is a powerful way to start, as you are focused on solving one very specific problem for a very specific niche group better than anyone else. Chances are your early adopters will give you valuable insight into how your product should eventually evolve into a platform.

This experiment is part of the Validation Patterns printed card deck

A collection of 60 product experiments that will validate your idea in a matter of days, not months. They are regularly used by product builders at companies like Google, Facebook, Dropbox, and Amazon.

Before the experiment

The first thing to do when planning any kind of test or experiment, is to figure out what you want to test. To make critical assumptions explicit, fill out an experiment sheet as you prepare your test. We created a sample sheet for you to get started. Download the Experiment Sheet.

Narrowing the focus

By narrowing down the product experience you are interested in testing and isolating it in its own single feature product, your test results will provide clearer evidence than if the feature had been integrated with other features. The fewer variables than can influence results, the better data reliability you will get.

Control damages to your brand

When you launch a product as a single-feature product, customer expectations are aligned to only expect a single feature. Especially for larger and more well-established brands that risk damaging their brand if experiments run wild, packacking the experiment as a single-feature product without ties to the brand’s core offering, can be beneficial.

After the experiment

To make sure you move forward, it is a good idea to systematically record your the insights you learned and what actions or decisions follow. We created a sample Learning Sheet, that will help you capture insights in the process of turning your product ideas successful. Download the Learning Sheet.


Before releasing as part of their core offering, UsabilityHub launched - a single feature product that was later incorporated into their core offering.
