THE HARDEST PARTS

ASK THE RIGHT QUESTION: INTERESTING

“We run the company by questions, not by answers. So in the strategy process we've so far formulated 30 questions that we have to answer […] You ask it as a question, rather than a pithy answer, and that stimulates conversation. Out of the conversation comes innovation. Innovation is not something that I just wake up one day and say 'I want to innovate.' I think you get a better innovative culture if you ask it as a question.”

Eric Schmidt (Executive Chairman of Alphabet Inc. / Former CEO Google)

ASK THE RIGHT QUESTION: SOLVABLE

What data do you have?

What other data can you get? How? Where? Privacy?

Resources available?

Development burden vs. added value?

PITFALLS

Overfitting

Leakage

Class Imbalance

Missing Data / Outliers
