What format do you use for formulating a hypothesis?

The hypothesis format is often used in the form: "If [action/change], then [expected result], because [justification]". For example:

If we add a "Buy in one click" button, then the conversion rate will increase by 10%, because users will be able to make purchases faster without unnecessary steps.

This format helps clearly articulate the assumption, expected effect, and logic, which facilitates hypothesis testing.
