Final answer:
The Lean UX process begins with a benefit hypothesis.
Step-by-step explanation:
The benefit hypothesis is a statement that describes the expected outcome or benefit of a design change or feature. It helps set the direction for the design process and guides the team in making decisions about the design.
For example, if a company wants to improve user engagement on their website, the benefit hypothesis could be: 'By adding a personalized recommendation feature, we expect to increase user engagement by 20%.'
