What is Data Science (DS)?
There is not a consensus on what Data
Science is!
- Data Science as an art/alchemy, not a
Science.
- No magical formula: each dataset is
unique.
“Data Science” term was first introduced in 1794 by Peter Naur.
There is not a consensus on what a Data
Scientist is or do!
- But, we can think about DS as a professional
that holds a collection of practices, wisdoms,
know-hows of data mining, and analysis.
Figure out hidden patterns in the raw data, solve business problems,
and support data-driven decision making.

Big Data in 60 Seconds“too big to fit on a single server, too unstructured to fit into a row-and-column database”.

Data-Driven: From Silos to Collaboration
https://www.ibm.com/blogs/business-analytics/data-driven-analytics-vision/
Foster culture that values data-driven philosophy as the
core element of decision making: transforming insights-
to-action supported by data.
“74% of firms say they want to be “data-driven,”
only 29% say they are good at connecting
analytics to action.”
https://go.forrester.com/blogs/16-03-09-think_you_want_to_be_data_driven_insight_is_the_new_data/
Mission:
Top-down and/or Bottom-up
strategies to take “data-driven”
advocates from department to an
enterprise endeavors.
Remember: ”Garbage in, garbage out”
Communicate | Educate | Share the Vision
Data-Driven: Roadblocks
 Culture
 Data and Analytics not seen as an engine of
value creation
 Lack of understanding on how to monetize on
(big) data
 Data Literacy
Focus on cultural change as the main driver for
transitioning to a data-driven culture.

The SWOTA Analysis gave voice to the team and documented the need
for a system that we all knew. Few months later, we started to implement
the first POS System.

Cultural Change by Law

Change firm’s “Laws”:
- Code of Conduct
- Operational Policies (OP)
- Standard Operating Procedure (SOP)
“Culture is a product of law. And laws create norms for society. This is why anyone who wants to change the culture of a country must try to change the norms of the country.”

The first rule in decision making is that one does not

Poor Decisions: Gut Feelings | Emotional | Experience
“When so much is unknown
and unknowable, conventional wisdom says to go
with your gut… worst time to rely on your
intuition is when you’re making high-stakes decisions.
Every scientific test of intuition shows that it’s
profoundly affected by cognitive biases”.
Source: “In high-stakes decisions, sometimes you’ve just got to go with your gut.”, Harvard Business School Publishing Corporation.
"There's no evidence whatsoever that I know of that shows more senior managers make
better decisions," Snijders said. "Experience has really shown to be relatively worthless
when it comes to making more accurate decisions.“
Chris Snijders, professor at Eindhoven University of Technology (Netherlands)
Source: Trust an algorithm with your business? The New York Times
Top 5 Cognitive Biases in DM
1. Overconfidence
2. Confirmation Bias
3. Unrealistically Positive Views of Self
4. Illusion of Control
5. Self-serving Attributions
“No problem in judgment and decision making is more prevalent and more potentially catastrophic than overconfidence”
(Plous, 1993, p. 217)
Considered the “mother of all biases” in DM
Anything to support our beliefs and values
Lack of humility
Extreme superstitious mindset
Take a lot of credit when succeed,
and too little blame when fail

Decision is usually made based on emotion
(pain, fear) and not rationally (Expected
Value).

The Abilene Paradox: The Management of Agreement
“The first rule in decision making is that one does not make a
decision unless there is disagreement.”
Peter Drucker
“The inability to manage agreement, not the inability to
manage conflict, is the essential symptom that defines
organizations caught in the web of the Abilene Paradox.”
