This document discusses the rise of predictive analytics and its value in enterprise decision making. It begins by explaining how predictive analytics has expanded from niche uses to a widely adopted competitive technique, fueled by big data, improved analytics tools, and demonstrated successes. A classic example given is credit scoring, which uses predictive models to assess credit risk. The document then provides examples of other areas where predictive models generate value, such as marketing, customer retention, pricing, and fraud prevention. It discusses how effective predictive models are built by using statistical techniques on data that describes predictive factors and outcomes. The document argues that predictive models provide the most value when applied to processes involving large volumes of similar decisions that have significant financial or other impacts, and where relevant electronic

About this paper
Predictive analytics is on the rise
as the number of successful
applications continues to
increase. Predictive models can
be used to generate better
decisions, greater consistency,
and lower costs.
Top areas in which predictive
models are generating significant
value for organizations include
marketing, customer retention,
pricing optimization and fraud
prevention—and the list
continues to grow.
This paper discusses how
predictive models are built, ideal
situations for applying them,
calculating their return on
investment, key predictive
modeling trends and more. With
predictive analytics, organizations
in both government and industry
can get more value from their
data, improve their decision
making and gain a stronger
competitive advantage.
Banks were early adopters, but now the range of applications and organizations
using predictive analytics successfully have multiplied:
Direct marketing and sales. Leads coming in from a company’s website can be scored
to determine the probability of a sale and to set the proper follow-up priority. Campaigns
can be targeted to the candidates most likely to respond.
Customer relationships. Customer characteristics and behavior are strongly predictive
of attrition (e.g., mobile phone contracts and credit cards). Attrition or “churn” models
help companies set strategies to reduce churn rates via communications and special
offers.
Pricing optimization. With sufficient data, the relationship between demand and price
can be modeled for any product and then used to determine the best pricing strategy.
Analytical pricing and revenue management are used extensively in the air travel,
hospitality, consumer packaged goods and retail banking sectors and are starting to
enter new domains such as toll roads and retail e-commerce.
Health outcomes. Models connecting symptoms and treatments to outcomes are
seeing wider use by providers. For example, a model can predict the likelihood that a
patient presenting a certain set of symptoms is actually suffering a heart attack, helping
ER staff determine treatment and urgency.
Insurance fraud. Many types of fraud have predictable patterns and can be identified
using statistical models for the purpose of prevention or for after-the-fact investigation
and recovery.
Improper public benefits payments and fraud. Health, welfare, unemployment,
housing and other benefits are sometimes paid when they should not be, wasting
taxpayers’ money and making benefits less available to those who deserve them.
Models similar to those used in insurance fraud help prevent and recover these losses.
Tax collections. Likely cases of additional tax owed (due to non-filers,
underreporting and inflated refunds) can be identified. The IRS and many state
governments use revenue collection models and are continually improving
them.
Predicting and preventing street crime, domestic abuse and terrorism. In
addition to link analysis techniques for investigating crimes, predictive models
help determine high-risk situations and hotspots for preventive action.
3. 3
Credit scoring for banks and
lenders is just one of many
areas where predictive
analytics is driving value.
Using a model to predict a
crucial business outcome, an
organization can turn an
“unknown unknown” into a
“known unknown” or, in other
words, a calculated risk.
Most business processes in
most organizations have the
potential to benefit from
predictive modeling.
BUILDING EFFECTIVE PREDICTIVE MODELS
Predictive models require data. Building, testing and refining these models require data that
describes 1) what’s known at the time a prediction needs to be made, and 2) the eventual
outcome. For example, to develop a model for heart attack risk presented by patients coming
into the ER, we’d need to have data describing patient symptoms when they arrived, and
then the subsequent outcome (were they suffering a heart attack or not). The ability to
generate data with these characteristics is a critical factor in the success of a predictive
modeling application.
Statistical techniques, such as linear regression and neural networks, are then applied to
identify predictors and calculate the actual models. Software from the SAS Institute, IBM’s
SPSS, and the open-source statistical toolset “R” are often used for this modeling analysis
step.
After assembling the data, the analysts may find 20 predictive factors that are known for each
patient (in our ER example) and assign weights to them using statistical software (e.g., +50
points for abnormally low blood pressure). The statistical software uses algorithms to
optimize the model weighting factors, so that the combination produces the most accurate
predictions possible with the available data.
The resulting “score,” combining all the factors and their weights, will be an effective risk
index that can be used as a decision criterion along with other rules for patient treatment. The
score will be not only correlated with cardiac risk, but can be calibrated to have a specific
mathematical relationship. This is a crucial advantage; it takes this risk from being an
“unknown unknown” to a “known unknown” or, in other words, a calculated risk.
HIGH-VALUE APPLICATIONS FOR PREDICTIVE MODELING
Most business processes in most organizations have the potential to benefit from predictive
modeling. That said, there are certain situations where predictive models can be especially
beneficial in delivering a great deal of value:
Processes that require a large number of similar decisions
Where the outcomes have a significant impact, i.e., where there’s a lot at stake in terms
of money or lives
Where there’s abundant information in electronic data form available on which to base
decisions and measure outcomes
Where it’s possible to insert a model calculation into the actual business process, either
to automate decisions or to support human decision makers
Credit scoring meets the criteria for high-value application:
There is a steady stream of loan requests accompanied by information about the
borrowers
The result of each decision has a big financial impact and is captured in loan accounting
systems
The models fit into the loan decision processes in a logical way to support human
decisions
So does assessing cardiac risk:
Patient symptoms are now captured in electronic health records, as are diagnoses and
subsequent outcomes
Decisions about treatment have life-or-death implications
It’s possible to use a model to guide immediate treatment decisions once the patient’s
information is entered when they come in to the ER.
4. 4
CGI’s viewpoint is that
predictive models provide an
extremely effective way to get
more value from data, and
they have a wide range of
applications that have not
come even close to being
fully exploited yet.
CALCULATING THE ROI OF PREDICTIVE ANALYTICS
In many cases, it’s possible to measure the potential benefits and even estimate the return
on investment of a predictive model using a simple method—the swap set. As shown in the
table below, the swap set is the set of improved decisions made possible by a predictive
model.
An example application are sales leads coming into a company’s website. Once received, the
leads are either assigned to one of the inside sales representatives for immediate follow up,
or they receive an automated email response.
The company wants to increase sales with the same staffing level, so it develops a predictive
model to measure the probability of a lead converting to a sale. The assignment rules are
changed to incorporate the model by assigning high-probability leads to the sales reps. The
swap set compares the results of the former assignment logic, which was based on intuitive
logic, with the new model-driven logic. The result is an increase of $200,000 per month.
Existing processes
(predictive-model
supported process)
Assigned to rep Email only Total leads
Assigned to rep 1,000 leads 1,000 leads 2,000 leads
$1,000,000 sales
Email only 1,000 leads 7,000 leads 8,000 leads
$500,000 sales
Total leads 2,000 leads
$700,000 sales
8,000 leads
$600,000 sales
10,000 leads
$1,500,000 sales (model)
$1,300,000 sales (former)
+$200,000 from scoring
Swap set illustration for sales lead scoring example. Use of a lead assignment model results in different treatment
decisions compared to what would have been decided previously, and generates improved results with equal sales cost.
PREDICTIVE MODELING TRENDS
The biggest set of changes and advances in predictive modeling are coming about as a
result of the explosion in unstructured data—text documents, video, voice and images—
accompanied by rapidly improving analytical techniques. In a nutshell, predictive modeling
requires structured information—the kind found in relational databases. To make
unstructured data sets useful for this kind of analysis, structured information must be
extracted from them first.
One example is sentiment analysis from Web posts. Information can be found in customer
posts on forums, blogs and other sources that predict customer satisfaction and sales trends
for new products. It would be nearly impossible, however, to try to build a predictive model
directly from the text in the posts themselves. An extraction step is needed to get usable
information in the form of keywords, phrases and meaning from the text in the posts, as
shown in the graphic below. Then, it’s possible to look for the correlation between instances
of the phrase “problems with the product”, for example, and spikes in customer service calls.

Illustration of information flow and process for a sentiment analysis application
Every form of unstructured data (e.g., text, images, video and sound) is accompanied by a
set of extraction techniques that enable usable information to be pulled out of the raw data
and used for analysis, including predictive modeling. With that step taken, the principles for
finding high-value applications of predictive modeling are the same for unstructured as for
structured information: high-value decisions, data in computerized form on both outcomes
and potential predictors, and a way to insert a model into the actual decision process.
CONCLUSION
CGI’s viewpoint is that predictive models provide an extremely effective way to get more
value from data, and they have a wide range of applications that have not come even close
to being fully exploited yet. The Big Data phenomenon will only increase the number of high-
value uses for predictive modeling in government and industry.
At the same time, predictive analytics are not appropriate or even feasible for all applications.
As with any powerful technology, care must be taken to implement predictive models
pragmatically in ways that produce real value.
An important challenge to greater adoption is that the talent needed to analyze data, create
models and implement them successfully is in short supply. Organizations looking to get
more value from the their data assets through predictive analytics will be wise to invest in
analytical training and mentoring programs, along with the expertise of partner firms.
