Market Segmentation
• Market segmentation is the
subdividing of a market into distinct
subsets of customers.
Segments
• Members are different between
segments but similar within.

Segmentation Marketing
Definition
Differentiating your product and
marketing efforts to meet the needs
of different segments, that is,
applying the marketing concept to
market segmentation.

Primary Characteristics
of Segments
• Bases—characteristics that tell us why segments
differ (e.g. needs, preferences, decision
processes).
• Descriptors—characteristics that help us find and
reach segments.
• (Business markets) (Consumer markets)

A Two-Stage Approach
in Business Markets
Macro-Segments:
• First stage/rough cut
– Industry/application
– Firm size
Micro-Segments:
• Second-stage/fine cut
– Different customer needs, wants, values within macro-segment

Segmentation in Action
We segment our customers by letter volume, by postage
volume, by the type of equipment they use. Then we
segment on whether they buy or lease equipment.
Based on this knowledge, we target our marketing
messages, fine tune our sales tactics, learn which benefits
appeal to which customers and zero in on key decision
makers at a company.
—Kathleen Synnot, VP, Worldwide Marketing
Mailing Systems Division, Pitney Bowes, Inc.
[quoted in Marketing Masters (Walden and Lawler)]

Segmentation
If you’re not thinking segments, you’re not
thinking. To think segments means you have to
think about what drives customers, customer
groups, and the choices that are or might be
available to them.
—Levitt, Marketing Imagination

A Note on Positioning
Positioning involves designing an offering so that the
target segment members perceive it in a distinct and
valued way relative to competitors.
Three ways to position an offering:
1. Unique (“Only product/service with XXX”)
2. Difference (“More than twice the [feature] vs.
[competitor]”)
3. Similarities (“Same functionality as [competitor];
lower price”)
What are you telling your targeted segments?

Behavior-Based Segmentation
• Traditional segmentation
(eg, demographic,
psychographic)
• Needs-based segmentation
• Behavior-based segmentation
(choice models)

Steps in a Segmentation Study
• Articulate a strategic rationale for segmentation (ie, why are we
segmenting this market?).
• Select a set of needs-based segmentation variables most useful
for achieving the strategic goals.
• Select a cluster analysis procedure for aggregating (or
disaggregating customers) into segments.
• Group customers into a defined number of different segments.
• Choose the segments that will best serve the firm’s strategy,
given its capabilities and the likely reactions of competitors.

Segmentation: Methods
Overview
• Factor analysis (to reduce data before
cluster analysis).
• Cluster analysis to form segments.
• Discriminant analysis to describe
segments.

Cluster Analysis for
Segmenting Markets
• Define a measure to assess the similarity of customers on the
basis of their needs.
• Group customers with similar needs. Recommend: the “Ward’s
minimum variance criterion” and, as an option, the K-Means
algorithm for doing this.
• Select the number of segments using numeric and strategic
criteria, and your judgment.
• Profile the needs of the selected segments (e.g., using cluster
means).

Cluster Analysis Issues
• Defining a measure of similarity (or distance) between segments.
• Identifying “outliers.”
• Selecting a clustering procedure
– Hierarchical clustering (e.g., Single linkage, average linkage, and minimum
variance methods)
– Partitioning methods (e.g., K-Means)
• Cluster profiling
– Univariate analysis
– Multiple discriminant analysis

Discriminant Analysis for
Describing Market Segments
• Identify a set of “observable” variables
that helps you to understand how to reach
and serve the needs of selected clusters.
• Use discriminant analysis to identify
underlying dimensions (axes) that
maximally differentiate between the
selected clusters.

Interpreting Discriminant
Analysis Results
• What proportion of the total variance in the descriptor data
is explained by the statistically significant discriminant
axes?
• Does the model have good predictability (“hit rate”) in each
cluster?
• Can you identify good descriptors to find differences
between clusters? (Examine correlations between
discriminant axes and each descriptor variable).

Output
• The following clusters are quite close
together and can be combined with a
small loss in consumer
• grouping information:
• i) clusters 7 and 5 at 0.27,
• ii) clusters 1 and 6 at 0.28, ii)
• fused cluster 7-5 and cluster 2 (0.34).
• However, when going from a four-cluster
solution to a three-cluster solution, the
distance to be bridged is much larger
(1.11);
• thus, the four-cluster solution is indicated
by the ESS.
• In addition, four seems a reasonable
number of segments to handle based on
managerial judgment.

PDA profiles
• Cluster 1. Phone users who use Personal
Information Management software, to whom
Email and Web access, as well as Multimedia
capabilities are important.
• Cluster 2. People who use messaging services and
cell phones, need remote access to information,
appreciate better monitors, but not for multi-media
usage.

PDA profiles..
Cluster 3. Pager users who have a high need for fast
information sharing (receiving as well as sending)
and also remote access. They use neither email
extensively, nor the Web, nor Multi-media, but do
require a handy, non-bulky device.
Cluster 4. Innovators who use cell phones a lot,
have a high need for Email, Web, and Multi-media
use. They also require a sleek device.

Profile based on Demos/behaviour

Name the segments
Cluster 1 - Sales Pros:
Cluster 1 consists mainly of sales professionals: 54% of the cluster members
indicated Sales as their occupation. They use the cell phone heavily, and many
(45%) own a PDA already; practically all have access to a PC. Their work often
takes them away from the office. They mostly read two of the selected
magazines: 30% read BW. From the needs data, we see that they are quite price
sensitive.
Cluster 2 – Service Pros:
Cluster 2 is made up primarily of service personnel (39%) and secondarily of
sales personnel (23%). They use cell phones heavily, but only about one fifth
currently use a PDA. They spend much time on the road and in remote locations.
They read PC Magazine, 29%. From the needs data, we see that they are quite
price sensitive.

Name the segments…
Cluster 3 – Hard Hats:
Cluster 3 is made up predominantly of construction (31%) and emergency
(19%)
workers. They use cell phones, but usually do not own a PDA.
By the nature of their work, they have high information relay needs and
generally work in remote locations.
They exchange information with colleagues in the field (e.g. construction
workers on the site). Many read Field & Stream (31%) and also PC
Magazine. Note also from the needs data, that they are the least price
sensitive (willing to pay highest price plus monthly fee) and also have the
lowest income.
This apparent anomaly occurs because these folks are less likely to have to
pay for the device themselves, raising the question of whose preferences—
their own or their employers’—will drive the adoption decision

Name the segments…
Cluster 4 – Innovators:
Cluster 4 represents early adopters (see needs data),
predominantly professionals (lawyers, consultants,
etc.).
Every cluster member has access to a PC, 89
percent already own PDAs.
They read many magazines, especially BW 49%,
PCMag 32%. Most are highly paid and highly
educated.

Interpreting Cluster Analysis
Results
• Select the appropriate number of clusters:
– Are the bases variables highly correlated? (Should we reduce the data through factor
analysis before clustering?)
– Are the clusters separated well from each other?
– Should we combine or separate the clusters?
– Can you come up with descriptive names for each cluster (eg, professionals, techno-
savvy, etc.)?
• Segment the market independently of your ability to reach the
segments (i.e., separately evaluate segmentation and discriminant
analysis results).

demographics/behaviour
proc discrim data=temp outstat=outdisc method=normal pool=yes list
crossvalidate;
class cluster; priors prop;
vars age education etc… ;
run;
** all relevant vars. not used to create segment solutions;

This allows us a way to
target and profile future
customers:

•The first discriminant function above explains 51% the variation.
According to its coefficients, i.e., the four groups are particularly
different with respect to the amount away from the office.
•In addition, the function shares high correlation with the level of
education, possession of a PDA, and income.
•The second function explains 32% of the variance and primarily
distinguishes the occupation types construction/emergency from
sales/service, and the third function separates Sales and Service
types.

Correspondence Analysis
• Provides a graphical summary of the interactions in a table
• Also known as a perceptual map
– But so are many other charts
• Can be very useful
– E.g. to provide overview of cluster results
• However the correct interpretation is less than intuitive,
and this leads many researchers astray

Interpretation
• Correspondence analysis plots should be interpreted by
looking at points relative to the origin
– Points that are in similar directions are positively associated
– Points that are on opposite sides of the origin are negatively
associated
– Points that are far from the origin exhibit the strongest associations
• Also the results reflect relative associations, not just which
rows are highest or lowest overall

Software for
Correspondence Analysis
• Earlier chart was created using a specialised package called
BRANDMAP
• Can also do correspondence analysis in most major statistical
packages
• For example, using PROC CORRESP in SAS:
*---Perform Simple Correspondence Analysis—Example 1 in SAS OnlineDoc;
proc corresp all data=Cars outc=Coor;
tables Marital, Origin;
run;
*---Plot the Simple Correspondence Analysis Results---;
%plotit(data=Coor, datatype=corresp)

Tandem Segmentation
• One general method is to conduct a factor
analysis, followed by a cluster analysis
• This approach has been criticised for losing
information and not yielding as much
discrimination as cluster analysis alone
• However it can make it easier to design the
distance function, and to interpret the results

Tandem k-means Example
proc factor data=datafile n=6 rotate=varimax round reorder flag=.54 scree out=scores;
var reasons1-reasons15 usage1-usage10;
run;
proc fastclus data=scores maxc=4 seed=109162319 maxiter=50;
var factor1-factor6;
run;
• Have used the default unweighted Euclidean distance
function, which is not sensible in every context
• Also note that k-means results depend on the initial cluster
centroids (determined here by the seed)
• Typically k-means is very prone to local maxima
– Run at least 20 times to ensure reasonable maximum

Cluster Analysis Options
• There are several choices of how to form clusters in
hierarchical cluster analysis
– Single linkage
– Average linkage
– Density linkage
– Ward’s method
– Many others
• Ward’s method (like k-means) tends to form equal sized,
roundish clusters
• Average linkage generally forms roundish clusters with
equal variance
• Density linkage can identify clusters of different shapes

Cluster Analysis Issues
• Distance definition
– Weighted Euclidean distance often works well, if weights are chosen
intelligently
• Cluster shape
– Shape of clusters found is determined by method, so choose method
appropriately
• Hierarchical methods usually take more computation time than k-
means
• However multiple runs are more important for k-means, since it can be
badly affected by local minima
• Adjusting for response styles can also be worthwhile
– Some people give more positive responses overall than others
– Clusters may simply reflect these response styles unless this is adjusted
for, e.g. by standardising responses across attributes for each respondent

MVA - FASTCLUS
• PROC FASTCLUS in SAS tries to minimise the root mean
square difference between the data points and their
corresponding cluster means
– Iterates until convergence is reached on this criterion
– However it often reaches a local minimum
– Can be useful to run many times with different seeds and choose
the best set of clusters based on this RMS criterion
• See http://en.wikipedia.org/wiki/K-means_clustering for
more k-means issues

Howard-Harris Approach
• Provides automatic approach to choosing seeds for k-
means clustering
• Chooses initial seeds by fixed procedure
– Takes variable with highest variance, splits the data at the mean,
and calculates centroids of the resulting two groups
– Applies k-means with these centroids as initial seeds
– This yields a 2 cluster solution
– Choose the cluster with the higher within-cluster variance
– Choose the variable with the highest variance within that cluster,
split the cluster as above, and repeat to give a 3 cluster solution
– Repeat until have reached a set number of clusters
• I believe this approach is used by the ESPRI software
package (after variables are standardised by their range)

Another “Clustering” Method
• One alternative approach to identifying clusters is to fit a
finite mixture model
– Assume the overall distribution is a mixture of several normal
distributions
– Typically this model is fit using some variant of the EM algorithm
• E.g. weka.clusterers.EM method in WEKA data mining package
• See WEKA tutorial for an example using Fisher’s iris data
• Advantages of this method include:
– Probability model allows for statistical tests
– Handles missing data within model fitting process
– Can extend this approach to define clusters based on model
parameters, e.g. regression coefficients
• Also known as latent class modeling

Segmentations via Choice Modelling

Choice Models
1. Observe choice:
(Buy/not buy => direct marketers
Brand bought 
 packaged goods, ABB)
2. Capture related data:
– demographics
– attitudes/perceptions
– market conditions (price, promotion, etc.)
3. Link
1 to 2 via “choice model”  model reveals
importance weights of characteristics

Behavior-Based Segmentation
Model
Stage 1: Screen products using key attributes to identify the “consideration
set of suppliers” for each type of customer.
Stage 2: Assume that customers (of each type) will choose suppliers to
maximize their utility via a random utility model.
Uij = Vij + ij
where:
Uij =Utility that customer i has for supplier j’s product.
Vij =Deterministic component of utility that is a function of product and supplier attributes.
ij =An error term that reflects the non-deterministic component of utility.

Specification of the
Deterministic Component of
Utility
Vij =  Wk bijk
k
where: i =an index to represent customers, j is an index to represent
suppliers, and k is an index to represent attributes.
bijk=i’s perception of attribute k for supplier j.
wk=estimated coefficient to represent the impact of bijk on the utility
realized for attribute k of supplier j for customer i.

A Key Result from this Specification:
The Multinomial Logit (MNL) Model
If customer’s past choices are assumed to reflect the principle
of utility maximization and the error (ij) has a specific form
called double exponential, then:
eVij
pij =––––––
k eVik
where:
pij =probability that customer i chooses supplier j.
Vij=estimated value of utility (ie, based on estimates of bijk)
obtained from maximum likelihood estimation.

Managerial Uses of
Segmentation Analysis
• Select attractive segments for focused effort (Can use models
such as Analytic Hierarchy Process or GE Planning Matrix).
• Develop a marketing plan (4P’s and positioning) to target
selected segments.
– In consumer markets, we typically rely on advertising and channel members
to selectively reach targeted segments.
– In business markets, we use sales force and direct marketing. You can use
the results from the discriminant analysis to assign new customers to one of
the segments.

Checklist for Segmentation
Studies
• Is it values, needs, or choice-based? Whose values and needs?
• Is it a projectable sample?
• Is the study valid? (Does it use multiple methods and multiple measures)
• Are the segments stable?
• Does the study answer important marketing questions (product design,
positioning, channel selection, sales force strategy, sales forecasting)
• Are segmentation results linked to databases?
• Is this a one-time study or is it a part of a long-term program?

Concluding Remarks
In summary,
• Use needs variables to segment markets.
• Select segments taking into account both the attractiveness of segments
and the strengths of the firm.
• Use descriptor variables to develop a marketing plan to reach and serve
chosen segments.
• Develop mechanisms to implement the segmentation strategy on a
routine basis (one way to do this is through information technology).
