Test an idea before building more
The Lean Startup
Choose this if you have an idea but little evidence that people want it. Ries’s approach centers on testing assumptions through experiments and learning from customer behavior.
A framework for learning, not proof that your particular idea has demand.
Put the idea to work
Plan a small test
In your notebook or notes app, name one customer and one action that would show interest. Add the smallest test you could run and the result that would make you continue or change direction.
Example
Before building an invoice-reminder app, help one freelancer send reminders manually. Check whether they ask to use it again.
You’ll have: a customer, an observable action and a small test.
