MARKET SEGMENTATION THAT PRODUCES RESULTS
By Leland D. ("Lee") Shaeffer, Managing Director, PLM Associates

Market segmentation is a powerful tool that enables the focus of resources, builds barriers to competition and produces a higher return on investment. While nearly everyone practices some form of segmentation out of necessity, additional care and thought can yield substantial improvement.

Why Segmentation is Important
If someone believes that his/her company can't be all things to all people, he already is segmenting the market and understands one of the key reasons for doing so - focus. Focus sales and marketing resources on the appropriate prospects. Focus product development resources on designing the optimum solution. Focus operational resources on ensuring the best possible interaction with customers

A well-defined market segment encompasses customers having similar needs, which is invaluable for specifying the product/solution. The segment will be sufficiently focused such that the solution will meet most if not all of the customers' criteria with a minimum of extra baggage - features and attributes that add cost but not value to that customer. Since the segment is well defined, customers and prospects can readily be identified and contacted for "Voice of the Customer" research.

Conversely, a segment defined too broadly will contain several sub-segments, each with certain needs that are different across the sub-segments. A solution that addresses those divergent needs will include extra features and compromises. At best, this adds minimal cost and complexity. At worst, it forces compromises in the design that renders the solution suboptimal for any particular sub-segment - and leaves the vendor vulnerable to competitors that are more discriminating.

Receiving "Disproportionate Returns" from Marketing Expenditures
Proper segmentation produces disproportionate returns on marketing expenditures. Consider that the return on marketing spend is a non-linear function. Starting near zero, there is a threshold below which the company is in the noise level. Most prospects receive too few impressions to become conscious of the message and take action. As spending increases, the prospect receives more impressions, and eventually the message reaches consciousness and leads to action. Additional outlay in this region of the curve produces "disproportionate" returns - doubling the amount of spend will more that double the return. Of course, further increases eventually produce diminishing returns. The resulting "return versus marketing spend" curve is therefore S-shaped.

For example, $10,000 spent on direct mail will produce a certain response. $10,000 spent instead on advertising will produce a response. Spending on both will generate the response from the direct mail and from the advertising, plus it will get additional response because people who saw the ad are more inclined to pay attention to the direct mail, and people who saw the direct mail will be more responsive to the advertising. Add an additional $10,000 for a trade show booth, and the resulting impressions from the booth, ads and direct mail will all reinforce each other - assuming all three reach the same prospects.

The spend should push well into the zone of disproportionate returns. Expenditures can be increased, of course, but a limited budget necessitates focusing existing resources. This can be accomplished with tighter market segmentation - narrowing the definition of the segment such that each prospect within that segment will receive more impressions per dollar spent.


The segmentation used for product definition purposes should be the same as that used for marketing purposes. Therefore, during the initial planning process, the expected marketing budget should be an important consideration since that will dictate the size of the target segment, which in turn will impact the solution design. The conventional approach is to decouple the product design and marketing budget decisions - easy to do since they are separated in time - but the results are likely to be suboptimal.

Market vs. Segment vs. Sub-segment vs. Niche
For purposes of this discussion, the distinctions between market, segment and sub-segment are relative. A market segment is a subset of a broader market, a sub-segment is a subset of the segment that may or may not qualify as a segment in its own right. It is useful to drive a stake in the ground and define the segment as the targeted group of customers and prospects. A sub-segment would be considered too small to be economically viable as the sole target; hence several are grouped together to achieve critical mass. A small segment may be considered a niche.

The terms are best considered relative since a market segment for one company may be an entire market to another, and a niche to yet another. Absolute definitions are therefore not practical.

An Approach to Market Segmentation
A key to segmentation is identifying inherent boundaries between prospective segments. These are defined by existing barriers that are difficult and/or expensive to cross. Analogous physical boundaries include oceans, rivers, canyons caused by erosion and mountain ranges. If the market segment is a "territory" that should be served as cost effectively as possible and defended against competition, it makes sense to define that territory using inherent boundaries that serve as barriers to competition. A territory ideally should not be bisected by inherent boundaries, since this increases the cost and difficulty of movement within the territory.

Inherent boundaries that separate market segments are caused by language, culture, geography, buying behavior, company size, regulations and self-referencing communities. The latter is particularly powerful and worth elaboration.

Self-Referencing Communities
A self-referencing community is comprised of people who know or know of each other, talk among themselves and use each other as "trusted sources". They may identify with certain labels and are "self referencing" since they, not a vendor, determine the community of which they feel a part. They generally belong to the same trade association, read the same set of periodicals, attend the same conferences and have their own vocabulary that is reflected in the key words they use for on-line searches. Because they talk among themselves and draw upon community members for product/vendor references, the word-of-mouth further compounds the return on marketing dollars.

The community may be defined by affiliations due to vertical industries, functional areas, geography and potentially by company size. Key indicators include the presence of trade associations, specialized publications and specialized conferences and trade shows. Geography refers to the local and regional business communities, not necessarily political boundaries. Company size is useful in defining products and targeting customers, since large companies can have different needs and behaviors, although there may not be clear self referencing communities based on size.

A word of caution: People may belong to several self-referencing communities, and not all of your target segment may identify with the same community. For example does a company that installs network cabling identify with the electrical contractor community or the data communications community? Could be both, either or neither.

Divide and Conquer
A larger segment may be subdivided into smaller segments by picking industry segments within an industry (for example, the 2002 NAICS - North American Industry Classification System - includes approximately 20 industries broken down into nearly 100 segments and over 2000 sub-segments). Another approach to subdividing is to cross industries with functional areas or geographically based business communities. It is useful to subdivide the market as much as feasible and then deliberately group the sub-segments into a target segment. This will help prevent overlooking inherent boundaries that may exist or missing some underlying differentiation that could impact product definition and marketing strategy.

How to Tell if a Segment is "Good"
After defining a target segment, it is helpful to step back and ask several questions:

  • What are the inherent boundaries? Can members of this segment be differentiated from members of adjacent segments?
  • Are there meaningful sub-segments within the segment? Even though these may be grouped to produce an economically viable segment, they are likely to impact the product design and marketing strategy.
  • Is the segment too large? If it will be hard to defend, the solution definition becomes diffused and the marketing expenditures are unlikely to get above the noise level, consider focusing on a sub-segment.
  • Can the segment be reached in a cost-effective way? The answer is usually yes for a self-referencing community and can be no if the segment, as defined, artificially groups together disparate sub-segments and niches. A "no" may also signify that the market segment is defined using product/usage variables, not true market variables.

When all is said and done, market segmentation often is an inexact science. Don't be afraid to experiment.
