new
technologies magically reveal
statistical trends

computing power
!
BIG DATA

the ROOT cause of a SLOW network
It takes IMMENSE SKILL to set up
a VALID STATISTICAL ANALYSIS

expectations
seem a little unrealistic
Answers are there...
they just need to be
harvested
from this vast pool of data!

Expectation #1
That expectation
assumes:
Data Quality
Data Security
Time Synchronization
Data Set Understanding
Domain Expertise
Functional Understanding
Algorithmic Programming Skill
Deep Statistical Expertise
REALITY #1
New Technologies,
Advanced Software &
Computing Power do
All the
heavy lifting
for people

Expectation #4
Big Data
IS
real
Big Data
IS
changing our lives
Big Data
IS
something we have to
be knowledgeable about
Big Data
IS
misunderstood
We are NOT a representative sample of our company
We generally have more STEM training
We generally have more daily analytical experiences
How many people have taken a stats class?
How many people use the scientific method?
How many people wish their staff would?
Who has recently performed a Chi-squared test?
Who has recently performed at t-test?
Who has done a correlation analysis?
Who has done a regression analysis?
Big Data success requires a tremendous amount of
human

time, skill, knowledge & interpretation!
REALITY #3
Answers are NOT data & data is NOT information

value
comes from the
consumption
of information NOT the
production
of information.
Real vs. Perceived Value
If we just
provide
the Information…
Do we care if the message is
received
?
Do we care if the message is
understood
?
Do we care if the proper
action
is taken?
Do we know how people
process
information?
Are we JUST providing information or are we helping the business to
achieve a result
?

Let's Provide REAL VALUE
REAL VALUE
What Could Possibly
Get in the Way?
Statistics
Assumptions
Attention
Perception
Information Overload
Motivation
Speed
But dude... I can multitask!
An individual has been described by a neighbor as follows: “Steve is very shy and withdrawn, invariably helpful but with very little interest in people or in the world of reality. A meek and tidy soul, he has a need for order and structure, and a passion for detail.” Is Steve more likely to be a
librarian
or a
farmer
?
So what can I do to leverage Big Data effectively?
