Use interviews when you need to understand a problem and recent behavior. Use a landing page when a specific audience and offer are ready for a bounded commitment test. Use a manual pilot when the largest uncertainty is whether you can create useful value. Choose the test by the decision it can change.
These tests aren’t interchangeable forms of “validation.” Existing market evidence and direct customer research answer different questions, as the U.S. Small Business Administration explains. Your test is useful only when its evidence limit is written before you run it.
What should you know before choosing a test?
- Interviews reveal problem language, recent behavior, alternatives, and decision context.
- A landing page tests response to a message or offer under a specific traffic condition.
- A manual pilot tests delivery, workflow, and stronger commitment before automation.
- No one test proves demand, delivery, repeat use, margin, and scale at the same time.
When is an interview the right test?
Choose interviews when the main uncertainty is what people actually do, what they tried, what they avoid, or how a decision gets made. Ask about a recent event rather than inviting a prediction about an idea you want them to like.
Record the context, the current workaround, the cost of the problem, and the next action the person already takes. Enthusiasm is a signal about the conversation. It isn't proof of payment or repeat behavior.
When does a landing page fit better?
A landing page fits when the audience, problem, promise, and next action are specific enough to expose to a known traffic source. Define what counts as a meaningful response and what the page can’t tell you.
A signup can show that a message earned attention under those conditions. It can't establish that the person will use the product, pay, return, or receive value. Don't inflate a low-commitment signal into a business conclusion.
When should you run a manual pilot?
Run a manual pilot when delivery is the key uncertainty and you can define the participant, service boundary, time, data, and stop rule. Manual work can teach you where value is created and where the workflow breaks before you automate the wrong thing.
A successful pilot supports a bounded delivery conclusion. It doesn't prove acquisition, repeat purchase, margin, or scale unless the design observed those things.
How do you choose with a decision stack?
| Step | Question |
|---|---|
| Uncertainty | What do you not know that could change the plan? |
| Observable behavior | What can someone do or show instead of merely say? |
| Commitment | What level of time, data, or money is proportionate? |
| Delivery | What part of creating value must be observed? |
| Stop rule | What result would make you narrow, revise, or stop? |
Suppose you don't know whether independent consultants need a structured proposal review or simply better examples. Start with interviews about recent proposal decisions. If the problem becomes specific, test a bounded review invitation. Run a manual pilot only when the delivery question is the one that still matters.
How should you interpret a mixed result?
Write the observation before the explanation. A weak response may reflect the audience, message, channel, timing, or test design. A positive response may reflect curiosity rather than durable value. Preserve the ambiguity and choose which uncertainty deserves the next test.
What to do next
- Write the decision that the test could change.
- Name the smallest observable behavior connected to that decision.
- Set the commitment, evidence limit, and stop rule before launch.
- Record what happened and choose continue, narrow, revise, pause, or stop.
