# Validate the idea before expanding the build.

Start by identifying the uncertain assumption: who has the problem, whether the proposed workflow helps, or whether the solution is technically feasible. Choose a small experiment that can answer that question. Interviews, an interest test, a prototype or a focused MVP may each be useful at a different stage. A launch is a chance to gather evidence; it does not guarantee demand or paying customers.

Plan your first release

## Practical guides to building an MVP.

Work through your budget, timeline, features and platform choice. Then discuss the development requirements for your app or platform.

§ The problem

Building a wide feature set before understanding the customer can make the next decision more expensive. A long specification does not replace evidence that the target user needs the core outcome.

§ The outcome

A documented hypothesis, evidence from the chosen experiment and a next decision: refine, test again, build a focused MVP or stop.

§ Step by step

## How to do it

1. 01
  ### Define one question
  Name the target user, problem and assumption. Write what evidence would make you change direction.
2. 02
  ### Choose the smallest useful experiment
  Use interviews for the problem, a prototype for an uncertain interaction, a proof of concept for technical risk, or a working MVP for the complete user task.
3. 03
  ### Agree scope and evidence
  Define participants, success observations, exclusions, ownership and any spending before running the test. Avoid universal conversion benchmarks.
4. 04
  ### Observe actual behaviour
  Separate comments, sign-ups, task completion, return visits and payments. Record where people fail and what they need help with.
5. 05
  ### Decide the next release
  Compare the evidence with your original question. Keep the limitations visible and agree the next experiment or first-release scope.

§ FAQ

## Common questions

### Do I need a complete app to validate an idea?

Not always. Start with the uncertainty you need to resolve. A conversation, prototype or focused test may answer the question before you invest in a working product.

### What if I have several assumptions to test?

Prioritise the assumption most likely to change the decision to build. Record what each experiment tests so you can interpret the results.

### Do I have to buy advertising?

No. Recruiting participants, interviews or a pilot with a known customer may be more appropriate. If paid acquisition is part of the experiment, agree the budget, audience and measurement first.

### Does an MVP guarantee paying customers?

No. An MVP creates a way to test a working product with users. Demand and willingness to pay need evidence from the intended audience.
