2. Rephrase the case: “So basically what you’re saying is that…is that
right?”
3. Ask clarifying question: “Can I ask some background questions before
I get started?...what do you mean by...”. Don’t assume anything. Different

revenue in order to validate or invalidate my initial hypothesis”
3. Ask questions to Gather data: don’t forget to think out loud and explain
why you are asking a question”
4. Identify key insights: if there is a key insight that invalidate your initial

cost problem. Let’s gather data on the company’s cost
