“Prejudice against algorithms is
magnified when the decisions
are consequential.”
What would you do when
every decision counts?
4%Worldwide average profit
margin in retail: 4%
4‰German average profit margin
in retail: 4‰
Your Customer gives you this
All you got to keep is that
— –Libby Rittenberg
“Economic profits in a system of
perfectly competitive markets
will, in the long run, be driven
to zero in all industries.”
Who is using Big Data Today?
Where Big Data is Used

Digital Marketing: More Data
Financial Services: Faster Data

• Drill-down analysis … misunderstood or
distorted
• Metrics dashboards … contradictory and
confusing
• Monthly reports … ignored after two
iterations
• In-house analyst teams … overworked
and powerless

— Everyone at Blue Yonder, all the time
99.9% of all business decisions
can be automated
How Decisions are Being Made
90% No Decision is made
— Robin Sharma
“Making no decision is a
decision. To do nothing. And
nothing always brings you
nowhere..”
Business Rules for Beginners
Not doing anything is the simplest business
rule in the world – and also the most popular
90% No Decision is made
9% Decision Follows Rule
Business Rules in Action
Advanced Business Rules
Computers are machines following rules. This
means business rules are programs.
• Business rules are like programs – written by
non-programmers
• Business rules can be contradictory,
incomplete, and complex beyond
comprehension
• Business rules have no built-in feedback
mechanism:“It is the rule, because it is the rule”
Business rules are Programs,
just not very good ones.
— Mark Twain
“It ain’t what we don’t know
that causes trouble, it’s what we
know for sure that just ain’t so”
1% Human Decision making
Human Decision Making has
two systems – and only one is
rational.
Not quite Almost there That’s it.
— Daniel Kahneman
“All of us would be better
investors if we just made fewer
decisions.”

Substitution
Availability heuristic
Texas Sharpshooter Fallacy
Rhyme as reason effect
Over-justification effect
Zero-risk bias
Framing effect
Illusory correlation
Sunk cost fallacy

Inattentional Blindness
Benjamin Franklin effect

Anecdotal evidence
Negativity bias
Loss aversion
Backfire effect

• Abraham Lincoln and John F. Kennedy were both
presidents of the United States, elected 100 years
apart. 
• Both were shot and killed by assassins who were
known by three names with 15 letters, John Wilkes
Booth and Lee Harvey Oswald, and neither killer
would make it to trial.
• Lincoln had a secretary named Kennedy, and
Kennedy had a secretary named Lincoln.
• They were both killed on a Friday while sitting
next to their wives, Lincoln in the Ford Theater,
Kennedy in a Lincoln made by Ford.

Computers making decisions
(cold, fast, cheap, rational)
• A machine learning algorithm is a system that
derives a set of rules based on a set of data
• It is based on systematic observation, double-
checking and cross-validation
• There is no magic, just data – and without data
there is no magic either

“Correlation doesn’t imply
causation, but it does waggle its
eyebrows suggestively and
gesture furtively while
mouthing‘look over there’”
— Warren Buffett
“I checked the actuarial tables,
and the lowest death rate is
among six-year-olds, so I
decided to eat like a six-year-
old.”
More than half of the apps on
a typical iPhone home screen
are predictive applications.

Categorizing Analytics
Descriptive
• Focused on gathering and
collecting data
• Key challenges: data volume
and data variety
• Key outcome: hindsight
• Examples: reports, dashboards
• Answers “What happened?”
Predictive
• Focused on understanding
and explaining data
• Key challenges: data velocity
and complexity
• Key outcome: insight
• Examples: prediction models
• Answers: “Why did it happen
and what will happen next?”
Prescriptive
• Focused on anticipating and
recommending action
• Key challenges: execution
• Key outcome: foresight
• Examples: decision support,
predictive apps
• Answers: “What should we do?”

Categorizing Analytics
Explicit
• Analytics are a key visible
feature of the program
• Programs are used by trained
analysts and data scientists
• Regular interaction during
business hours
Integrated
• Analytics are included in
another program
• Analytics are consumed in-
context by business users
• Frequent, but irregular
consumption during business
hours
Embedded
• Analytics are invisibly part of a
complex process
• Decisions are made and
executed in the process
• Constant and ongoing
optimization 24/7
