Market Analysis and Segmentation
The STP framework: segmentation, targeting, and positioning in practice
Summary: This post explains market analysis and segmentation through the STP framework — segmentation, targeting, and positioning. It covers the standard bases for segmentation (demographic, geographic, psychographic, behavioural), the criteria for evaluating segment attractiveness, targeting strategies, and positioning in the consumer's mind. The post pairs Nike (United States) with Safaricom (Kenya), applies the five core elements (why, what, when, who, how), and closes with an original pros-and-cons analysis.
Introduction — Why Segmentation Matters
In 2026, Nike reported revenue above USD51 billion and continued to operate a portfolio strategy that separates its brand into distinct consumer segments: Jordan Brand, Converse, and the core Nike line, each targeting different demographic and psychographic groups. In Kenya, Safaricom's customer base of more than 50 million across East Africa is served through distinct product tiers — from prepaid voice to M-PESA to enterprise solutions — each addressing a different segment need.
Philip Kotler defined segmentation as "the process of dividing a market into distinct groups of buyers with different needs, characteristics, or behaviour, who might require separate products or marketing programmes." The STP framework — segmentation, targeting, positioning — is the standard approach for converting a broad market into actionable strategy. Markets are not homogeneous, and firms that treat them as such misallocate resources.
This post covers the STP framework in four parts: the framework itself, the bases of segmentation, targeting strategy, and positioning. Every section addresses the five core elements — why it is done that way, what is supposed to be done, when it is done, who does what, and how it is supposed to be done — followed by a blog analysis of the pros and cons.
- Why — Markets are heterogeneous; undifferentiated marketing wastes resources on uninterested buyers
- What — Divide the market into actionable segments and select the ones the firm can serve profitably
- How — Through segmentation research, targeting evaluation, and positioning strategy
The analytical approach applied across this post is comparative case analysis: paired international and emerging-market examples, examined through the STP framework, with original assessment of strengths and limitations.
Chapter 1 — The STP Framework
Definition
The STP framework — Segmentation, Targeting, Positioning — is the standard marketing planning sequence introduced by Kotler and widely adopted in marketing practice. It converts a heterogeneous market into a strategic plan by first dividing the market into segments, then selecting the segments to serve, and finally designing a positioning for each selected segment.
- Segmentation — dividing the market into distinct groups based on shared characteristics
- Targeting — evaluating segment attractiveness and selecting which segments to serve
- Positioning — designing the offering and image to occupy a distinct place in the target's mind
Explanation
The STP sequence exists because markets are not homogeneous. Buyers differ in needs, budgets, geography, and behaviour. Attempting to serve all buyers with one offering forces compromises that satisfy no one completely. Segmentation identifies the differences; targeting selects the segments where the firm has competitive advantage; positioning creates a distinctive offer for each selected segment. The three stages are sequential — targeting cannot be done before segmentation, and positioning cannot be designed before targeting.
- Segmentation analysis — quantitative and qualitative research to identify distinct buyer groups
- Target evaluation — scoring each segment on size, growth, profitability, competition, and fit
- Positioning design — value proposition, messaging, and offer tailoring for each chosen segment
- Implementation planning — pricing, distribution, and promotion decisions aligned to the position
The interpretive insight is that STP is not a one-time exercise. Segments shift as demographics change, as competitors move, and as technology creates new possibilities. Firms that revisit STP periodically detect these shifts earlier than those that treat segmentation as a fixed foundation.
The Five Core Elements
Every concept in this subject must address five questions in a fixed order. Together they form the operational logic of the discipline.
- Why it is done that way — Markets are heterogeneous; STP matches firm capabilities to specific buyer needs
- What is supposed to be done — to Segment the market, select target segments, position the offer for each
- When it is done — During strategy design; refreshed annually and whenever the market shifts materially
- Who does what — Marketing leadership owns STP; research provides data; product and sales execute
- How it is supposed to be done — Through market research, segmentation analytics, and positioning testing
Case Study
International: Nike (United States). Nike operates a segmented brand portfolio: the core Nike brand for performance and lifestyle, Jordan Brand for premium basketball-inspired fashion, and Converse for a distinct heritage-driven segment. Each brand targets a distinct demographic and psychographic group, with tailored positioning, pricing, and distribution. Revenue above USD51 billion in 2026 reflects the effectiveness of the multi-segment approach.
Emerging market: Safaricom (Kenya). Safaricom segments its 50+ million customer base through product tiers: prepaid voice and data for mass-market consumers, M-PESA for financial services users across income levels, and enterprise solutions for business customers. Each segment receives a tailored offer, and the layered approach supports both mass-market reach and premium pricing where appropriate.
Blog Analysis — Pros and Cons
The evidence from Nike and Safaricom supports the following assessment.
- Pros: STP allows firms to serve multiple segments with tailored offers; both Nike and Safaricom demonstrate that segmentation enables premium positioning without abandoning mass-market reach.
- Cons: STP requires ongoing research investment; segmentation that is not refreshed becomes outdated, and Nike and Safaricom both face the challenge of detecting new segment shifts before competitors do.
Chapter 2 — Bases of Segmentation
Definition
Segmentation bases are the variables used to divide a market into distinct groups. Kotler grouped the standard bases into four categories: geographic, demographic, psychographic, and behavioural. Each basis reveals different aspects of consumer difference; most sophisticated segmentation combines multiple bases.
- Geographic — nation, region, city size, climate, urban vs. rural
- Demographic — age, gender, income, education, occupation, family life cycle
- Psychographic — social class, lifestyle, personality, values
- Behavioural — usage rate, occasion, benefits sought, loyalty status
Explanation
Each segmentation basis has strengths and limitations. Demographic segmentation is easy to measure but often weak at predicting behaviour — two consumers of the same age and income can have entirely different needs. Psychographic and behavioural segmentation are better at capturing motivation but require more research investment. The most useful segmentations combine demographic variables (which are easy to reach through media) with psychographic or behavioural variables (which explain why consumers buy). Effective segmentation also satisfies five criteria.
- Measurable — the segment's size and characteristics can be quantified
- Substantial — the segment is large and profitable enough to serve
- Accessible — the segment can be reached through available channels
- Differentiable — the segment responds differently from other segments
- Actionable — the firm can design effective offers for the segment
The interpretive insight is that the choice of segmentation basis determines the strategy. A firm that segments only demographically will compete on price and product features. A firm that segments behaviourally can compete on relevance and relationship, which are harder for competitors to copy.
The Five Core Elements
- Why it is done that way — Different segmentation bases reveal different kinds of buyer difference; combining bases produces more actionable segments
- What is supposed to be done — Select segmentation bases that satisfy the five criteria and align with firm capabilities
- When it is done — During strategy design; refreshed as market composition changes
- Who does what — Market research designs segmentation studies; brand and product teams apply the output
- How it is supposed to be done — Through surveys, behavioural data, and cluster analysis to identify natural segments
Case Study
International: Nike (United States). Nike's segmentation combines demographic (age, gender), psychographic (athletic identity, performance orientation), and behavioural (running frequency, gym membership, sports participation) bases. The Nike Run Club app, for example, segments by running frequency and pace, and serves tailored content and product recommendations. This behavioural segmentation produces personalised offers that demographic segmentation alone could not achieve.
Emerging market: Safaricom (Kenya). Safaricom segments its base using demographic and behavioural variables: prepaid vs. postpaid, urban vs. rural, and usage patterns for voice, data, and M-PESA transactions. The segmentation allows Safaricom to design offers like daily data bundles for prepaid users and enterprise solutions for business customers — different segments receiving different pricing structures and product features.
Blog Analysis — Pros and Cons
The evidence from Nike and Safaricom supports the following assessment.
- Pros: Behavioural and psychographic segmentation produces more actionable segments; both Nike and Safaricom combine multiple bases to reach buyers with tailored offers.
- Cons: Multi-basis segmentation requires sophisticated research infrastructure; smaller firms often cannot afford the depth of analysis required to combine bases effectively.
Chapter 3 — Targeting Strategy
Definition
Targeting is the process of evaluating segment attractiveness and selecting which segments the firm will serve. Kotler identified four broad targeting strategies: undifferentiated (mass) marketing, differentiated marketing, concentrated (niche) marketing, and micromarketing. The choice depends on firm resources, market variability, and competitive intensity.
- Undifferentiated marketing — one offer for the whole market; ignores segment differences
- Differentiated marketing — separate offers for multiple segments
- Concentrated (niche) marketing — one offer focused on a single segment
- Micromarketing — tailoring offers individual customers or local groups
Explanation
Segment attractiveness is evaluated on four criteria: size and growth, structural attractiveness (competitive intensity, substitute threats, buyer power), fit with firm objectives and resources, and expected profitability. The right targeting strategy depends on the firm's competitive position. Large firms with broad capabilities often use differentiated marketing; smaller firms with focused expertise often use concentrated marketing. In some categories, digital capabilities now make micromarketing — one-to-one personalisation at scale — economically viable.
- Segment size and growth — is the segment large enough and growing?
- Structural attractiveness — is the competitive intensity and buyer power manageable?
- Fit with firm objectives — does the segment align with firm strategy and capability?
- Expected profitability — does the segment generate sufficient return on investment?
- Resource capacity — can the firm serve the segment better than competitors?
The interpretive insight is that targeting is a resource-allocation decision. Every segment a firm chooses to serve requires investment; choosing too many segments dilutes resources and weakens competitive position in each.
The Five Core Elements
- Why it is done that way — Resources are finite; targeting focuses investment on segments where the firm can win
- What is supposed to be done — Evaluate segment attractiveness and select the segments to serve
- When it is done — During strategy design; revisited when market conditions change
- Who does what — Senior marketing leadership owns targeting decisions; research provides evaluation data
- How it is supposed to be done — Through segment attractiveness scoring, competitive analysis, and financial modelling
Case Study
International: Nike (United States). Nike uses differentiated marketing across multiple segments — performance athletes, lifestyle consumers, women's fitness, and youth — while also using micromarketing through its digital apps, which deliver personalised recommendations to millions of individual users. Revenue above USD51 billion in 2026 reflects the combination of broad reach and personalised targeting.
Emerging market: Safaricom (Kenya). Safaricom uses differentiated targeting across mass-market consumers, small and medium enterprises, and large corporates. The mass-market segment receives prepaid offers; enterprises receive solutions tailored to their scale. Safaricom's premium position, with Brand Strength Index above 90 in 2025, reflects the success of serving multiple segments with tailored offers.
Blog Analysis — Pros and Cons
The evidence from Nike and Safaricom supports the following assessment.
- Pros: Differentiated targeting allows firms to serve multiple segments without diluting focus; Nike and Safaricom both demonstrate that serving multiple segments effectively requires disciplined resource allocation.
- Cons: Differentiated targeting increases marketing and operations complexity; firms that expand into too many segments risk losing competitive position in each.
Chapter 4 — Positioning in the Consumer's Mind
Definition
Positioning is the act of designing the firm's offering and image to occupy a distinctive place in the target segment's mind. Ries and Trout introduced the term in 1972 to describe how consumers place brands into mental categories, and how firms can influence that placement. Positioning determines how consumers perceive the brand relative to competitors.
- Value proposition — the combination of benefits the brand promises to deliver
- Points of difference (PoD) — attributes or benefits the brand owns that competitors do not
- Points of parity (PoP) — attributes or benefits the brand shares with competitors, necessary to be considered credible
Explanation
Positioning works because consumers simplify a complex marketplace by placing brands into mental categories. A brand that is positioned as the leader in a category, or the specialist in a niche, occupies a distinct place in the consumer's mind that is difficult for competitors to displace. Effective positioning requires both points of difference (which make the brand distinctive) and points of parity (which make it credible). A brand that is distinctive but not credible in its category will be dismissed; a brand that is credible but not distinctive will be commoditised.
- Category positioning — defining the category the brand competes in
- Competitive positioning — defining how the brand differs from competitors within the category
- Value positioning — defining the price-quality relationship the brand offers
- Functional positioning — solving a specific problem better than alternatives
- Emotional positioning — connecting with consumers through values and identity
The interpretive insight is that positioning happens whether the firm manages it or not. Consumers form mental placements of brands based on every interaction they have. The firm's job is to make sure the placement is the one it wants.
The Five Core Elements
- Why it is done that way — Positioning determines how consumers perceive the brand and which brands they consider
- What is supposed to be done — Design an offer and image that occupies a distinctive place in the target's mind
- When it is done — During strategy design; reinforced through every communication and interaction
- Who does what — Brand leadership owns positioning; communications, product, and sales execute
- How it is supposed to be done — Through positioning statements, value propositions, and consistent execution
Case Study
International: Nike (United States). Nike positions on aspiration and performance through the "Just Do It" platform, which has been consistent for decades. Points of parity — athletic performance and product quality — are established across the category. Points of difference — empowerment, self-actualisation, cultural relevance — are owned by Nike in the athletic apparel market. The positioning is reinforced through athlete endorsements, cultural partnerships, and digital experiences.
Emerging market: Safaricom (Kenya). Safaricom positions on trust, presence, and everyday relevance in Kenya. Points of parity — network quality and service availability — are established across the telecom category. Points of difference — M-PESA integration, local agent network, and community presence — are owned by Safaricom and difficult for competitors to replicate. The Brand Strength Index above 90 in 2025 reflects the durability of this position.
Blog Analysis — Pros and Cons
The evidence from Nike and Safaricom supports the following assessment.
- Pros: Strong positioning creates durable competitive advantage; both Nike and Safaricom own distinctive positions that competitors have struggled to displace.
- Cons: Positioning constrains future flexibility; a brand that owns a specific position can find it difficult to move into adjacent categories without confusing consumers.
