Analytics for decision making: Business Value
through Use Cases
What do you really want to achieve?
Increased customer loyalty? Better customer engagement?
A greater share of wallet via cross-sell? New customers?
Lower attrition?
In other words, what is the use case? What exactly are the types of
business problems big data analytics likely to solve?

Creating a balance between Descriptive,
Predictive and Prescriptive Analytics
Descriptive Analytics Describe, show or summarise data in a meaningful
way such that, for example, patterns might emerge from the data.
Does not allow to make conclusions regarding any hypotheses we might have made.
Measures of central tendency Mode, Median, and Mean
Measures of spread Range, Quartiles, Absolute Deviation, Variance and
Standard Deviation.
Normally presented using Graphical and tabulation techniques or even plain commentary.
Creating a balance between Descriptive,
Predictive and Prescriptive Analytics
Predictive Analytics ( a subset of inferential
analytics)
Inferential analytics ~ are techniques that allow
to make generalisations about the populations.
Estimation inferential techniques Forecasting (demand)
Predictive modelling of events e.g. Product take-up, fraud
Hypothèses testing e.g. Effect of interest rate increase on credit defult risk and profit
margins
Effect of personalised marketing on customer loyalty
Prescriptive Analytics Analytics dedicated to finding the best course of action for a
given descriptive and inferential analytics insights.
Explores all possible scenarios (outcomes)
Incorporates real life operational factors in decision making e.g. real time capability, available analytics deployment platforms.
May play a role of recommending the best strategy to follow given the available insights
E.g. Given the number of transactions processed daily, the accuracy of the fraud model and the complexity of the fraud model, we should have real time fraud declines
Creating a balance between Descriptive,
Predictive and Prescriptive Analytics
Descriptive Analytics Understand at an aggregate level what is going on.
Summarize and describe different business aspects.
Predictive Analytics Need to know something about the future
Fill in the information that you do not have.
Prescriptive Analytics Need to provide users with advice on what action to
take.
Creating a balance between Descriptive,
Predictive and Prescriptive Analytics
Analytics skills are scarce: how do you
manage them?

Skills
Make a business
connection

expectations
Feed their love of tools and technologies
Pay them Well

Science Understanding
Treat them as distinct

support
The role of a Chief Analytics Officer in the Data

“It's Time To Welcome The Chief Analytics Officer To The C-suite”, Frank Bien - CEO of Looker.
• Chief Analytics Officer (CAO) – Deriving business value using big data and analytics

– New C-Level position Driven by organisations desire to turn big data into a strategic asset
– Few Organisations have the role of CAO defined within their existing c-suite, but have the “Advanced analytics head” at a lower level
– Owns the resulting ROI/NPV on both top line and bottom line numbers
Trends Driving the Chief Analytics Officer Role

ability to innovate quickly using big data and
analytics
