Principles of Marketing (COM5CJ303) — Module 2: Consumer Behaviour & Market Targeting (STP)
Lecture Notes • Complete Study Material
At the very core of modern marketing philosophy lies a profound appreciation of the customer. An enterprise can command state-of-the-art production engineering and abundant capital, but if it fails to decode the intricate psychological, social, and cultural stimuli that drive human purchasing choices, corporate failure is inevitable. This module delivers an exhaustive examination of Consumer Behaviour, Assael's matrix of buying types, the four foundational determinants of buyer actions, the five-stage Consumer Buying Decision Process, organizational buying dynamics (B2B vs. B2C), and the master strategic triumvirate of modern marketing: Market Segmentation, Target Market Selection, and Market Positioning (The STP Framework).
Unit 6: Meaning, Nature, and Conceptual Models of Consumer Behaviour
Consumer Behaviour is the dynamic study of how individuals, households, and groups select, buy, use, and dispose of goods, services, ideas, or experiences to satisfy their personal needs and desires. It blends cognitive psychology, social psychology, cultural anthropology, and microeconomics to explain what consumers buy, why they buy, when they buy, where they buy, and how often they buy.
Authoritative Definition
"Consumer behaviour is the behaviour that consumers display in searching for, purchasing, using, evaluating, and disposing of products and services that they expect will satisfy their needs."
Behavioral Definition
"Those acts of individuals directly involved in obtaining, using, and disposing of economic goods and services, including the decision processes that precede and determine these acts."
The Stimulus-Response Model of Buyer Behaviour (The Black Box Model)
The central paradigm of consumer analysis is the Stimulus-Response Model. Consumers are bombarded daily by external stimuli; these stimuli enter the buyer's conscious and subconscious mind (the "Black Box"), interact with personal characteristics and decision mechanics, and emerge as observable market responses:
Component Structural Flow:
- 1. Marketing & Environmental Stimuli:
- Marketing Mix Stimuli (The 4 Ps): Product design, List price, Distribution channels, Promotional campaigns.
- Environmental Forces: Economic growth/inflation, Technological automation, Political regulations, Cultural norms.
- 2. The Buyer's Black Box:
- Buyer Characteristics: Cultural, social, personal, and psychological filters that shape perception.
- Buyer Decision Process: The cognitive sequence of problem recognition, search, evaluation, choice, and post-purchase reaction.
- 3. Observable Buyer Responses (Output): Product choice, Brand choice, Dealer/Retailer choice, Purchase timing, Purchase transaction quantity, Brand advocacy or churn.
Types of Consumer Buying Behaviour (Assael's Matrix)
Consumer decision-making is not uniform. Purchasing a tube of toothpaste requires vastly different cognitive involvement and psychological deliberation than purchasing an apartment or a luxury car. Professor Henry Assael classified consumer buying behaviour into four distinct categories based on two critical dimensions: Degree of Buyer Involvement (High vs. Low) and Perceived Differences Between Competing Brands (Significant vs. Few):
| Involvement Level | Significant Brand Differences | Few Brand Differences |
|---|---|---|
| High Buyer Involvement | 1. Complex Buying Behaviour Consumer conducts extensive research, forms beliefs, evaluates attributes, and makes deliberate choices. High financial, social, or physical risk. Examples: Luxury cars, residential property, high-end enterprise laptops. | 2. Dissonance-Reducing Behaviour High financial involvement, but perceived brand differences are narrow. Buyer shops around, purchases relatively quickly, and faces post-purchase anxiety. Examples: Floor carpeting, diamond rings, airline tickets. |
| Low Buyer Involvement | 3. Variety-Seeking Behaviour Low involvement, but significant brand variety. Switching occurs for novelty, curiosity, or boredom, not dissatisfaction. Examples: Cookies, snack chips, ice cream flavors, bath soaps. | 4. Habitual Buying Behaviour Passive shopping without information search. Purchases made out of routine repetition and brand familiarity rather than loyalty. Examples: Table salt, matchboxes, cooking oil, paper towels. |
Strategic Marketing Implications of Assael's Quadrants
- Complex Behaviour Strategy: Marketers must supply extensive technical literature, comparison tools, certified endorsements, and highly trained sales consultants to guide the buyer through cognitive evaluation.
- Dissonance-Reducing Strategy: Marketers must provide reassuring post-sale communications, warranty certificates, user onboarding manuals, and responsive customer service to eliminate post-purchase buyer remorse.
- Variety-Seeking Strategy: Market leaders must dominate retail shelf space, prevent out-of-stock situations, and run frequent reminder ads; challenger brands must offer low trial prices, discount coupons, and free sample sachets.
- Habitual Behaviour Strategy: Marketers must use eye-catching packaging, prominent end-of-aisle point-of-sale displays, simple visual cues, and heavy repetitive broadcast advertising to keep the brand top-of-mind.
Factors Influencing Consumer Behaviour
Consumer purchasing decisions are the final output of an intricate web of cultural, social, personal, and psychological influences:
A. Cultural Factors (Broadest Influence)
- Culture: The foundational determinant of a person's wants and behavior, transmitted through family, schools, and religious institutions (e.g., preference for traditional attire during Indian festivals).
- Subculture: Distinct groups providing more specific socialization (nationalities, religions, racial groups, linguistic regions).
- Social Class: Relatively permanent, ordered divisions in society whose members share similar values, interests, and spending behavior (e.g., upper class luxury spending vs. middle class focus on home appliances and education savings).
B. Social Factors (Interpersonal Dynamics)
- Reference Groups:
- Membership Groups: Primary (family, close friends) and Secondary (colleagues, trade unions).
- Aspirational Groups: Groups a person aspires to join (e.g., aspiring athletes mimicking sports heroes).
- Dissociative Groups: Groups whose values or behavior a person rejects.
- Family: The most influential primary consumption unit. Marketers distinguish buying roles: Initiator, Influencer, Decider, Buyer, and User.
- Social Roles & Status: Products act as symbolic indicators of an individual's achieved corporate or social standing.
C. Personal Factors (Individual Demographics)
- Age & Life Cycle Stage: Consumption shifts across the Family Life Cycle (young singles spend on fashion/travel; young parents on baby care/insurance; empty-nesters on healthcare).
- Occupation & Economic Circumstances: Blue-collar workers purchase rugged workwear; corporate executives purchase bespoke suits and club memberships.
- Lifestyle (AIO Framework): Expressed in Activities, Interests, and Opinions. The VALS Framework segments consumers into 8 lifestyle profiles: Innovators, Thinkers, Achievers, Experiencers, Believers, Strivers, Makers, Survivors.
- Personality & Self-Concept: Trait theory; congruence between brand personality and consumer's actual vs. ideal self-concept.
D. Psychological Factors (Internal Drivers)
- Motivation:
- Maslow's Hierarchy: Physiological → Safety → Social → Esteem → Self-Actualization.
- Herzberg's Dual-Factor Theory: Hygiene factors prevent dissatisfaction; motivators actively drive brand choice.
- Perception:
- Selective Attention: Screening out irrelevant ads.
- Selective Distortion: Twisting facts to fit beliefs.
- Selective Retention: Remembering positive points of favored brands.
- Learning & Attitudes: Experiential conditioning (drives, cues, responses, reinforcement); enduring cognitive evaluations.
Unit 7: The Five-Stage Consumer Buying Decision Process
The buying process starts long before the actual cash transaction and continues long after the physical purchase. In high-involvement and complex purchases, consumers navigate five sequential stages:
The consumer perceives a meaningful difference between their actual state and their desired state. Need triggers:
- Internal Stimuli: Normal biological drives (hunger, thirst, fatigue) rising to a threshold level.
- External Stimuli: Commercial cues (seeing a billboard for a sports car, smelling freshly baked bread, noticing a friend's new smartphone).
Once the need is felt, the consumer seeks information across four primary sources:
- Personal Sources: Family, friends, neighbors (most credible and influential).
- Commercial Sources: Advertising, websites, salespersons, packaging, displays (informational, but biased).
- Public Sources: Mass media, consumer review organizations, Google reviews, YouTube unboxing channels.
- Experiential Sources: Handling, test-driving, examining, or using the product directly.
The Evoked Set: Out of the Total Set, search narrows options to the Awareness Set, then to the Consideration / Evoked Set (the small handful of 3–5 viable brands meeting acceptable criteria).
How the consumer processes information to evaluate brand choices. The consumer views each product as a bundle of evaluative attributes (e.g., for a smartphone: camera resolution, battery longevity, processor speed, OS, resale value, brand prestige).
- Compensatory Models: The consumer scores each brand across weighted attributes; a weakness in one attribute can be compensated by strength in another.
- Non-Compensatory Heuristics: Mental shortcuts where a single flaw eliminates a brand immediately (e.g., Conjunctive rule: must meet minimum cutoff on all criteria; Lexicographic rule: best brand on the single most important attribute wins).
The consumer forms brand preferences and a purchase intention. Intervening factors:
- Attitudes of Others: The intensity of a spouse's, parent's, or friend's negative attitude toward the chosen brand.
- Unanticipated Situational Factors: Sudden economic emergencies, stock-out, price hikes, or dealer unfriendliness.
- Perceived Risk: Financial, physical safety, and social embarrassment risks (alleviated via money-back guarantees, free trials, EMI financing).
- The Expectancy Disconfirmation Paradigm:• Performance < Expectations: Dissatisfaction (churn, negative word-of-mouth).• Performance = Expectations: Satisfaction (content, but vulnerable to competitors).• Performance > Expectations: Delight (high emotional loyalty, brand advocacy).
- Cognitive Dissonance (Buyer Remorse): A distressing state of psychological doubt after a major purchase, wondering whether one made the wrong choice.Marketer Remedy: Reassurance via welcome emails, VIP onboarding calls, testimonials, and responsive after-sales support.
The Digital Consumer Journey & Online Buying Dynamics
The proliferation of high-speed smartphones, e-commerce marketplaces, and algorithmic social media has fundamentally disrupted the traditional linear five-stage buying funnel. Modern digital consumer behavior is characterized by non-linear journeys, continuous peer validation, and omnichannel switching:
1. McKinsey's Circular Consumer Journey
Replaces the static funnel with a dynamic, circular feedback loop:
- Initial Consideration Set: Brand awareness based on cumulative brand impressions.
- Active Evaluation: Actively researching brands, crowdsourcing opinions from online reviews and vlogs.
- Moment of Purchase: Transaction execution (app, website, or offline store).
- The Loyalty Loop: Delighted consumers bypass active evaluation in subsequent purchases, entering an automated repurchase loop.
2. Google's Zero Moment of Truth (ZMOT)
Introduces a critical psychological stage between Stimulus and First Moment of Truth:
- Stimulus: Consumer sees a TV ad or Instagram post.
- ZMOT: Before visiting a store, researching online: ratings, YouTube reviews, comparison charts.
- First Moment of Truth (FMOT): The in-store or checkout decision.
- Second Moment of Truth (SMOT): The product usage experience.
Omnichannel Shopping Phenomena: Showrooming vs. Webrooming
Showrooming: The practice where a consumer visits a physical retail showroom to physically inspect, touch, and test a product, but subsequently purchases it online from an e-commerce platform at a discounted price.
Webrooming (Reverse Showrooming): The practice where a consumer extensively researches products, user ratings, and technical specifications online, but ultimately visits a local physical store to make the purchase (seeking immediate gratification, personal inspection, and zero shipping delays).
Organizational / Business Buying Behaviour (B2B vs. B2C)
Business-to-Business (B2B) Marketing involves selling goods and services to commercial enterprises, institutions, and government bodies for use in producing other goods or running administrative operations.
Distinct Characteristics of B2B Markets
- Derived Demand: Demand for business goods is derived from the demand for ultimate consumer goods (e.g., steel demand is derived from automobile demand).
- Inelastic Short-Term Demand: Total demand for business components is not significantly affected by short-term price fluctuations.
- Fluctuating Demand (Accelerator Principle): A small percentage increase in consumer demand triggers a massive percentage increase in capital equipment demand.
- Fewer but Larger Buyers: A handful of corporate clients account for the majority of a supplier's total revenue.
The Decision-Making Unit (The Buying Center)
The 7 roles in the Webster and Wind Buying Center framework:
- Initiators: People who first request the purchase.
- Users: Employees who will physically operate the equipment.
- Influencers: Technical engineers who formulate technical specs.
- Deciders: Senior executives with formal authority to choose.
- Approvers: Authorize the financial budget.
- Buyers: Formal purchasing agents who negotiate contracts.
- Gatekeepers: Receptionists/assistants controlling information flow.
Units 8 & 9: Market Segmentation: Theory, Bases, and Criteria
No single commercial enterprise can satisfy all buyers in an entire market. Buyers are too numerous, geographically dispersed, and widely divergent in their buying requirements. Market Segmentation is the strategic process of dividing a large, heterogeneous market into distinct, smaller, homogeneous sub-markets of consumers who share similar needs, characteristics, or behavioral patterns.
Criteria for Effective Segmentation (The MASDA Framework)
To ensure that a market segment is commercially viable and actionable for managerial targeting, it must fulfill five statutory marketing criteria:
- 1. Measurable: The size, purchasing power, demographic volume, and profile characteristics of the segment must be capable of being measured with reasonable statistical precision.
- 2. Accessible: The segment must be effectively reached, communicated with, and physically served through existing distribution and advertising channels.
- 3. Substantial: The segment must be large or profitable enough to warrant designing and executing a customized marketing program. A segment should be the largest possible homogeneous group worth pursuing with a tailored marketing mix.
- 4. Differentiable: The segments must be conceptually distinguishable and respond differently to distinct marketing mix elements and promotional campaigns. If married and unmarried women respond identically to a perfume promotion, they do not constitute separate segments.
- 5. Actionable: Effective marketing programs can be formulated for attracting and serving the segments within the enterprise's financial and managerial capabilities.
Comprehensive Bases for Segmenting Consumer Markets
| Segmentation Base | Segment Variables & Parameters | Practical Corporate Application |
|---|---|---|
| 1. Geographic | Nations, states, regions, climate, population density (urban, semi-urban, rural), metro tiers (Tier-1, Tier-2, Tier-3 cities). | McDonald's offering Maharaja Mac (no beef/pork) in India; air conditioner manufacturers targeting tropical humid regions; warm thermal wear in northern climates. |
| 2. Demographic | Age, gender, family size, family life cycle, income level, occupation, education, religion, generation (Gen Z, Millennials). | Titan watches: Fastrack (youth), Raga (women), Nebula (high-net-worth gold luxury); insurance policies tailored to senior retirees. |
| 3. Psychographic | Social class, lifestyle patterns (AIO: Activities, Interests, Opinions), personality traits, personal core values. | Royal Enfield positioning motorcycles for rugged adventurers; organic health foods targeting eco-conscious urban health enthusiasts. |
| 4. Behavioral | Occasions (regular vs. festive/wedding), benefits sought, user status, usage rate (heavy, medium, light), brand loyalty, readiness stage. | Cadbury Celebrations gifting boxes during Diwali; toothpaste brands segmented by benefit (Sensodyne for sensitivity, Colgate for cavity protection, Close-up for fresh breath). |
Unit 10: Target Market Selection Strategies
Once market segmentation is completed, the firm evaluates the attractiveness of each segment and selects one or more segments to enter. Marketers evaluate segments across three dimensions: Segment Size and Growth, Structural Attractiveness (intensity of competition, threat of substitutes, buyer bargaining power), and Company Objectives and Resources.
1. Undifferentiated (Mass) Marketing
The firm ignores segment differences and goes after the entire market with one single marketing offer and 4P mix.
Focus: Mass distribution and mass advertising, aiming for universal appeal (e.g., standard table salt, agricultural produce, original Coca-Cola).
Advantage: Maximum economies of scale in manufacturing and promotion; low inventory costs.
Disadvantage: Highly vulnerable to niche competitors who tailor superior offerings to specific sub-groups.
2. Differentiated (Segmented) Marketing
The firm targets several different market segments and designs separate, customized marketing programs for each.
Focus: Marriott International offering distinct hotel brands: Ritz-Carlton (ultra-luxury), Marriott Hotels (full-service executive), Courtyard by Marriott (business traveler), Fairfield Inn (budget economy).
Advantage: Generates higher total sales, broader market share, and diversified revenue streams.
Disadvantage: Significantly increases manufacturing, R&D, promotional, and inventory carrying costs.
3. Concentrated (Niche) Marketing
Instead of pursuing a small share of a large mass market, the firm pursues a large share of one or a few narrow sub-segments (niches).
Focus: Highly specialized firms (e.g., Rolls-Royce luxury motor cars, specialized orthopedic surgical implant manufacturers, premium gluten-free bakeries).
Advantage: Excellent strategy for small and medium enterprises with limited financial capital; builds dominant, defensible customer loyalty.
Disadvantage: High risk if the niche segment contracts or if a large corporate entrant enters the niche.
4. Micromarketing (Local & Individual)
Tailoring products and marketing programs to suit the tastes of specific local individuals and locations:
- Local Marketing: Tailoring brands and promotions to the needs of local customer groups (cities, neighborhoods, specific retail stores).
- Individual Marketing (One-to-One / Mass Customization): Customizing products to individual consumer specifications (e.g., Dell customized computers, Nike By You custom footwear, bespoke tailoring).
Unit 11: Market Positioning Strategies & Perceptual Mapping
After segmenting the market and selecting the target segment, the firm must determine how it will differentiate its offering from competitors. Positioning is the act of designing the company's offering and brand image in such a manner that it occupies a distinctive, valued, and desirable place in the mind of the target customer relative to competing brands.
As advertising pioneers Al Ries and Jack Trout famously stated in their classic work: "Positioning is not what you do to a product. Positioning is what you do to the mind of the prospect. That is, you position the product in the mind of the prospect."
A company's Value Proposition represents the full mix of benefits upon which the brand is differentiated and positioned:
- 1. More for More: Providing the most upscale product, prestigious craftsmanship, and service at a premium price (Mercedes-Benz, Rolex, Apple, Four Seasons Hotels).
- 2. More for the Same: Offering comparable luxury or superior features at the same price as standard competitors (Lexus challenging European luxury sedans; Xiaomi offering flagship phone features at mid-tier prices).
- 3. The Same for Less: Offering standard quality, everyday reliability at a deep, permanent discount (D-Mart, Walmart, generic pharmaceutical drugs).
- 4. Less for Much Less: Stripping away luxury amenities to deliver bare-bones utility at ultra-low prices (IndiGo bare airfares, motel chains).
- 5. More for Less: The winning short-term proposition, but extremely difficult to sustain profitably in the long run due to high cost pressures.
Perceptual Mapping (Positioning Map)
A Perceptual Map is a visual two-dimensional spatial coordinate graph that plots consumer perceptions of competing brands along two critical evaluative buying dimensions (e.g., Price on the Vertical Axis and Quality / Performance on the Horizontal Axis).
- Strategic Diagnostic Role: Reveals how customers mentally perceive competing market offerings.
- Identifying White Spaces: Highlights unoccupied market territory (gaps) where unmet consumer demand exists, allowing the enterprise to launch a new brand with minimal direct head-to-head rivalry.
- Monitoring Repositioning: Tracks shifts in brand image over time following major advertising overhauls.
Classic Bases / Strategies for Brand Positioning
1. Attribute / Feature
Associates the brand with a specific physical or performance attribute: Volvo (World's safest cars), Subway ("Eat Fresh").
2. Benefit Positioning
Positions on the primary functional benefit delivered: Sensodyne (Relief from tooth sensitivity), Head & Shoulders (Dandruff control).
3. Price-Quality
Positions at opposite ends of the economic spectrum: Taj Hotels (Ultimate luxury hospitality) vs. Ginger Hotels (Smart budget hospitality).
4. Use / Application
Associates the brand with a specific usage context: Gatorade (Athletic replenishment after intense exercise), Vicks VapoRub (Nighttime cold relief).
5. Product User
Positions the product for a distinct user profile: Johnson & Johnson (Gentle for newborn infants), Nike (Dedicated serious athletes).
6. Competitor
Directly contrasting against an established market titan: Avis ("We're number two, so we try harder"), 7-Up (The refreshing "Uncola").
Brand Repositioning
Repositioning involves altering an existing brand's position in the consumer's mind when its original positioning becomes obsolete, oversaturated, or commercially unviable. A classic example is the Tata Nano: originally positioned as "the world's cheapest car", it suffered from a negative consumer social stigma (nobody wanted to be seen driving "the cheapest car"). Tata Motors subsequently repositioned it as a vibrant, fuel-efficient, smart city car for urban youth.
Mapping consumer decision stages alongside market segmentation variables for an electric two-wheeler manufacturer entering urban Indian markets:
| Decision Stage | Consumer Cognitive Action | Segmentation Variable | Strategic Marketing Action |
|---|---|---|---|
| 1. Need Recognition | Realizes rising petrol fuel costs & daily commute expense | Demographic (Urban Commuters, Office-goers) | Highlight daily running cost savings (₹0.20/km vs. ₹2.50/km) |
| 2. Info Search | Compares EV battery range, charging time & specs online | Psychographic (Tech-savvy / Eco-conscious) | SEO, YouTube unboxing reviews, digital interactive range calculators |
| 3. Evaluation | Weighs Brand A (Range) vs. Brand B (Price / Styling) | Behavioral (Benefit Sought: Safety & Reliability) | Free doorstep test rides, 5-year battery warranty promise |
| 4. Purchase | Selects model with flexible monthly EMI financing | Demographic (Income Tier, Salaried Youth) | 0% interest EMI options at dealership, fast paperless approvals |
| 5. Post-Purchase | Assesses fast charging network availability & service support | Behavioral (Brand Loyalty & Word-of-Mouth) | Automated 24/7 roadside assistance, mobile app OTA updates, referral rewards |
Summary Comparative Matrix: The STP Strategic Process
| Strategic Pillar | Core Executive Question | Primary Analytical Tools & Deliverables |
|---|---|---|
| 1. Segmentation (S) | "Who are all the different potential customer groups that exist in the overall market?" | Geographic, Demographic, Psychographic, and Behavioral variables. Evaluated via the MASDA criteria. |
| 2. Targeting (T) | "Which specific customer group(s) can we serve best, most profitably, and with lowest risk?" | Segment size/growth, Porter's Five Forces, Mass vs. Segmented vs. Niche vs. Micromarketing strategies. |
| 3. Positioning (P) | "How do we want our brand to be uniquely perceived in the target customer's mind compared to competitors?" | Brand Value Proposition (Price vs. Benefits), Perceptual Mapping, Attribute/Benefit/Competitor positioning statements. |
