“Big data is like teenage sex:
everyone talks about it,
nobody really knows how to do it,
everbody thinks everyone else is
doing it,
so everyone claims they do it…”
—Dan Ariely

Big Data:
a large volume of information
coming from different sources,
normally in real time,
in a structured or unstructured way
A more professional definition…

How much
data do
WE
generate?

5. @danielutges
Why are Big Data
analytics useful?

6. @danielutges
What are Big Data analytics used for?
• From qualitative guesses to quantitative
i.e. I think most of my customers may need X and Y
Big Data: 65% of my customers are purchasing X and Y in the same order
• From reactive to proactive
i.e. The pump broke. We have to stop production to fix it ASAP!
Big Data: The pump will collapse in 65 days +/- 5%
We should make the preventive changes next week.

results as quickly
as possible
