Oxford College of Marketing -Needs-based Market Segmentation By Emeritus Professor Malcolm McDonald
Needs-based Market Segmentation – the unchanging bedrock of successful strategy
By Emeritus Professor Malcolm McDonald
There is a widely held belief that new media and changing patterns of behaviours have made traditional market segmentation irrelevant. They haven’t, nor will they in future. These are feeble excuses from lazy and incompetent marketing departments, who fail to use the tried and tested process of needs-based market segmentation to understand these new consumer behaviour patterns. Given the current fearsome economic circumstances, this is one of the biggest challenges and opportunities we face if we are to survive in a fast-changing world.
A Harvard Business Review article by Christensen in December 2005 reported that the reason for a 90 per cent failure rate of 30,000 new products was poor market segmentation. In February 2006, also in an HBR article, Yankelovich reported on the widespread failure of market segmentation initiatives.
The reasons aren’t hard to pinpoint. A whole edition of the Journal of Marketing Management in 2009 was devoted to market segmentation, discussing issues such as what segmentation bases to use, such as size of purchase, customer characteristics, product attributes, benefits sought, service quality, psychographics and, more recently, with the advent of relationship marketing, one-to-one. Such debates always have been largely irrelevant and ‘production-orientated’. For example, it is clearly nonsense to segment on the basis of socio-economics demographics, geodemographics and the like. Other than at a very high level of aggregation, not all As behave the same, Nor do all 18-24 year old women, nor does everyone in a specific geographical area.
The justification for saying this is that anyone who says “We segment markets by …..” is totally missing the point. First any market has to be correctly defined in terms of needs, the very opposite of “we’re in the pensions market”, as a pension is only one of many ways of satisfying the needs for retirement income. Remember what happened to IBM then they defined their market as mainframes and Gestetner who defined their market as duplicators. The history of commerce is replete with failed companies who defined their market in terms of what they sold rather than the needs to be satisfied.
Secondly, any market consists of 100 per cent of what is bought, where it is bought, how it is bought, who buys it, how it is used and why it is bought and used in these ways.
Needs-based market segmentation, as spelled out in detail in Market Segmentation: how to do it; how to profit from it”, is a simple step-by-step process, which space doesn’t allow to be spelled out here. Suffice to say that the correct methodology for segmenting markets has always been to understand the many different actual purchase combinations that take place in a market, as shown in Figure. 1. The resulting micro segments are all actual purchase behaviours and there are usually as many as 40 of these in any market, but since most companies can only deal effectively with up to 10, a simple clustering routine is used to bring together those micro segments that share approximately the same needs – ie. Segments,

Figure 1 – Micro Segments
A simplified example of the end result of this process is shown in table 1 for the toothpaste market. Figure 2 shows the end result of the process for purchasers of IT and IS products. Particularly in relation to Figure 2, it can easily be appreciated how products, services and communication channels and messages must vary in accordance with the needs and profile of each segment. Competitors without such a segmented approach are of necessity ‘marmalading’ their offer over the average IT buyer and just cannot understand why this major global supplier is so successful and why they don’t have to compete on price.

A propos the issue of whether new channels, new media (such as i-tunes, You Tube, etc.) and subsequent changing behaviours has made traditional segmentation irrelevant, the resounding answer is ‘NO’.
In Figures 3 and 4, the buying process (listed in the left hand column and the actual behaviours of just two of ten segments of a global travel company in respect of their use of media such as the internet, interactive TV etc. for each stage are shown.
Even a cursory glance at this would show that, unless these different actual behaviours by segment were known by this travel company, the offers made to their customers and their communication strategies would be hopelessly misplaced.

The Times letter shown in Figure 5 is a hilarious explanation of what goes wrong when needs-based segmentation isn’t carried out and is a classic example of why most communications, especially direct mail, miss the mark completely.

Finally, the link between shareholder value creation and excellent marketing has been firmly established during 50 years of research. Table 2, taken from Brian Smith’s 2003 Cranfield PhD, shows this link. It also shows on the right what gurus like Philip Kotler and others consider to be worldclass marketing.

The order is important and justifies my belief that without proper market segmentation, all strategies fail in the long run.
