>> One type of question I remember back from the day was how many tennis balls get sold
in the US or in the world each year.
And the idea was that it's not about the actual number but it's about how you come
up with the answer and what kind of logic, excuse me, what kind of logic do you use,
you know, what's your thinking process so that tells a lot about, you know,
how you think about things and how you understand, you know,
business or in the supply chain, how forecasting,
marketing and all that kind of works.
So just, it's a critical thinking tool that makes you stop
and make sure you're doing it correctly.
