What is Product Validation?
Product validation is the process of testing whether a product idea holds up against real evidence before significant resources are committed — evidence of demand, willingness to pay, technical feasibility and business viability. It replaces 'we believe' with 'we tested', turning assumptions into confirmed or discarded hypotheses.

In more depth
Validation starts by listing the assumptions an idea depends on and ranking them by risk: which one, if wrong, kills the idea? Each high-risk assumption then gets the cheapest test that could genuinely disprove it — customer interviews, a landing-page demand test, a concierge pilot, a pricing experiment, a technical spike. The sequencing matters: demand risk is usually tested before feasibility risk, because engineers can build almost anything, but nobody can make customers want it. Honest validation defines the pass threshold before the test runs, so results are judged against a pre-agreed bar rather than rationalised afterwards.
Why it matters
The gap between what people say in a meeting and what they do with their time and money is where products die. Validation closes that gap while the cost of being wrong is still a test, not a build. It also changes the quality of decisions downstream: a business case or requirements document written on validated evidence carries a different weight from one written on optimism — and stakeholders can see which they are being asked to approve.
A product example
Before building a premium tier, a team tests willingness to pay directly: they add an upgrade page describing the tier at its intended price and measure how many active users click through and start the flow. Against a pre-agreed threshold, the observed intent is a third of what the revenue model assumed — so the tier is repriced and rescoped before a line of it is built.
