it will be clear to everyone that 'Data Science' is dead….”

Data Science: Another Perspective
Data Science has evolved from Data Mining
“Data science innovation was driven initially by new types of data – this
opened up possibilities for new questions to be asked and new analyses
to be run
This innovation led to enterprise technologies that can process data and
build models at scale
The required skills to work in data science are different than those for
data mining
o Strong technical skills – statistics, coding, databases – are still required
o But, there is now the need to problem solve in a way that is more
meaningful to the business since data scientists are now involved in
business strategy
o This requires the ability for data scientists to communicate their findings in
a non-technical manner to business users”

Applies to these

as well

Example: The Traditional Customer Life Cycle
11
Copyright © BI Research, 2014
Customer Analytics: BI Perspective
Descriptive: How many of customers churned in the last month?
Descriptive: How many of these were profitable?
Diagnostic: Why did these profitable customers churn?
Predictive: How many profitable customers are likely to churn next
month?
Prescriptive: How can we reduce this profitable customer churn rate?
12

Customer Analytics: Data Science Perspective
Business and data understanding: What is the difference between a
highly profitable customer and an average customer?
Data preparation and modeling: What are the characteristics of a
highly profitable customer?
Deployed predictive model: Will this new customer be profitable?
How much revenue is this new customer likely to generate?

Tableau Story Points

Copyright © BI Research, 2014
Gaining Business Value from Advanced Analytics
Managers don’t have to be data scientists, but they need to:
• Understand the fundamental principles well
enough to appreciate the business
opportunities, communicate with technologists
and evaluate proposals for data science projects
• Be willing to invest in data and experimentation
and supply the required resources
• Keep the BI and data science team on track
Understand how to gain competitive advantage (or parity) from data
science in the context of the corporate strategy and that of
competitors
Maintain momentum over competitors
Collaborate with, and examine data science projects in other
organizations

Final Thoughts
Organizations need to build a high quality data
science team that is managed by a
knowledgeable person such as a chief analytics
officer
Keep humans in the decision making loop
Mining and analyzing personal data raises
important ethical and privacy issues that should
not be ignored
Applying BI analytics to a well-structured problem
versus exploratory data mining requires different
skills and tools, but these two approaches need
to be able to work together
