Marketing I: Concept, Mix, Strategic Planning, STP, Product and Pricing Decisions

Unit 8 is the most Kotler-shaped unit of the Commerce paper: the vocabulary is standard, the frameworks are few, and the questions test whether you can name the framework from its description and put its stages in order. This first chapter covers the first half of the unit — what marketing is and the philosophies it grew through, the marketing mix and channels, how a strategic marketing plan is built, segmentation-targeting-positioning, product decisions from product levels to the life cycle and new-product development, and pricing. Sequences are the paper's favourite trick here, so every staged model is given as a numbered list in the order the examiner expects.

1. Concept and approaches, marketing channels and the marketing mix

The American Marketing Association defines marketing as the activity, set of institutions and processes for creating, communicating, delivering and exchanging offerings that have value for customers, clients, partners and society at large. Kotler's shorter version — meeting needs profitably — carries the same two ideas: marketing starts from a need that exists in the customer, and it must pay. The older view of marketing as selling what the factory has made is one of the philosophies below, not the definition.

The five marketing philosophies, in the order they arose
ConceptStarting pointBeliefEnds
ProductionFactoryConsumers favour products that are widely available and cheapProfit through volume and efficiency
ProductFactoryConsumers favour the best quality and performance — the 'better mousetrap' fallacyProfit through product quality
SellingFactoryConsumers will not buy enough unless pushed by aggressive selling and promotionProfit through sales volume
MarketingTarget marketKnow the customer's needs and satisfy them better than competitors doProfit through customer satisfaction
Societal / holisticSociety and all stakeholdersSatisfy the customer's wants in a way that preserves the consumer's and society's long-run well-beingProfit with social responsibility
⚠️ Selling concept versus marketing concept
Levitt's contrast is the examiner's favourite: selling focuses on the needs of the seller and starts from the product; marketing focuses on the needs of the buyer and starts from the market. The selling concept works 'inside-out' and the marketing concept 'outside-in'. Kotler's holistic marketing then adds four components — relationship, integrated, internal and performance marketing — and 'societal marketing' is the version that adds society's welfare as a third pole beside company profit and consumer wants.

A marketing channel is the set of interdependent organisations that make a product available for use. Manufacturer-to-consumer is a zero-level (direct) channel; adding a retailer makes it one-level, a wholesaler and retailer two-level, and an agent, wholesaler and retailer three-level. Intermediaries exist because they perform functions — breaking bulk, assortment, storage, financing, risk-bearing, information — more cheaply than the producer could. The marketing mix is the set of controllable tools the firm blends to produce the response it wants in the target market. McCarthy's four Ps are product, price, place and promotion; Booms and Bitner's services extension adds people, process and physical evidence; Lauterborn's four Cs restate the Ps from the customer's side as customer solution, cost, convenience and communication.

2. Strategic marketing planning and segmentation, targeting and positioning

Strategic marketing planning happens at three levels — corporate, business-unit and product — and the corporate level does four things: defines the mission, establishes strategic business units, assigns resources to them, and assesses growth opportunities. The two portfolio tools the paper asks are the BCG growth-share matrix, which places SBUs by market growth rate and relative market share into stars, cash cows, question marks and dogs, and the GE-McKinsey nine-cell matrix, which uses industry attractiveness and business strength. Ansoff's product-market grid gives four growth routes — market penetration (existing product, existing market), market development (existing product, new market), product development (new product, existing market) and diversification (new product, new market). Porter's generic strategies — overall cost leadership, differentiation and focus — describe how a business unit competes once it has chosen where.

  1. Business mission — the specific purpose of the unit within the corporate mission.
  2. SWOT analysis — external environment for opportunities and threats, internal for strengths and weaknesses.
  3. Goal formulation — objectives made specific, measurable and time-bound.
  4. Strategy formulation — the game plan for reaching the goals, chosen from Porter's generic strategies and alliances.
  5. Programme formulation — the marketing programmes that carry the strategy out.
  6. Implementation, then feedback and control — measuring results and correcting the plan.

Segmentation, targeting and positioning is the sequence at the heart of target marketing. Segmentation divides a heterogeneous market into groups that are internally similar and externally different. Consumer markets are segmented on four bases — geographic, demographic (age, gender, income, family life cycle, social class), psychographic (lifestyle, personality, values) and behavioural (occasions, benefits sought, user status, usage rate, loyalty). A usable segment must be measurable, substantial, accessible, differentiable and actionable. Targeting then chooses which segments to serve, on a spectrum from undifferentiated (mass) marketing through differentiated, concentrated (niche) and micromarketing down to marketing to the individual. Positioning is the act of designing the offer and image so that it occupies a distinctive place in the mind of the target customer, summarised in a value proposition and drawn on a perceptual map.

🧠 The BCG cells in one line
High growth, high share — star (build). Low growth, high share — cash cow (harvest, fund the others). High growth, low share — question mark (build or divest). Low growth, low share — dog (divest). The vertical axis is market growth and the horizontal axis is relative market share, plotted from high on the left to low on the right — a detail the paper has turned into a question.

3. Product decisions: levels, line and mix, life cycle and new-product development

A product is anything offered to a market to satisfy a want — a physical good, a service, an experience, an event, a person, a place, a property, an organisation, information or an idea. Kotler's five product levels build outward: the core benefit (rest, for a hotel), the basic product (a bed and a bathroom), the expected product (clean sheets, a working lamp), the augmented product (what exceeds expectation) and the potential product (all possible future augmentation). Consumer goods are classified by shopping habit into convenience goods (staples, impulse and emergency goods), shopping goods, specialty goods and unsought goods; industrial goods into materials and parts, capital items, and supplies and services.

The four dimensions of a product mix
DimensionMeaningExample for a consumer-goods firm
WidthNumber of different product lines the company carriesSoaps, detergents, toothpaste, tea — width four
LengthTotal number of items across all linesAll brands counted together
DepthNumber of variants offered of each product in a lineOne toothpaste in three sizes and two flavours — depth six
ConsistencyHow closely the lines are related in end use, production, channels or otherwiseAll fast-moving goods through the same grocery channel — high consistency

A product line is a group of closely related products; line decisions include line stretching — downmarket, upmarket or two-way — line filling, line modernisation and line pruning. The product life cycle describes sales and profit over four stages. Introduction has slow sales growth, negative or minimal profit, heavy promotion to build awareness and a choice between skimming and penetration pricing. Growth has rapid acceptance, rising profit and entry of competitors; the firm improves quality, adds features and enters new segments. Maturity, the longest stage, has slowing growth, peak-then-declining profit and intense competition; the firm modifies the market, the product or the marketing mix. Decline has falling sales and profit; the choices are to maintain, harvest or drop.

  1. Idea generation — from customers, scientists, competitors, employees, channel members.
  2. Idea screening — dropping poor ideas early; the two errors are the drop-error (rejecting a good idea) and the go-error (advancing a poor one).
  3. Concept development and testing — turning the idea into a consumer concept and testing it with target customers.
  4. Marketing strategy development — target market, positioning, sales and profit goals, the mix.
  5. Business analysis — sales, cost and profit projections against company objectives.
  6. Product development — the concept becomes a physical prototype.
  7. Market testing — the product and programme are tried in a real setting.
  8. Commercialisation — full launch: when, where, to whom and how.
⚠️ The life cycle is a sales curve, not an adoption curve
Rogers' adopter categories — innovators 2.5%, early adopters 13.5%, early majority 34%, late majority 34%, laggards 16% — describe who buys when, and are often set beside the PLC; but they are a diffusion model, not the life cycle. Questions that ask 'the stage in which competitors enter and profit rises' want growth; 'the stage with the highest profit' wants maturity, where profit peaks before it declines.

4. Pricing decisions: factors, policies and strategies

Price is the only element of the mix that produces revenue; the others produce costs. Kotler's six-step procedure sets prices by selecting the pricing objective (survival, maximum current profit, maximum market share, market skimming, product-quality leadership), determining demand and its price elasticity, estimating costs, analysing competitors' costs, prices and offers, selecting a pricing method, and selecting the final price. The factors that shape the decision are internal — objectives, the rest of the mix, costs, organisation — and external — the nature of the market (pure competition through monopoly), demand, competitors' prices, and legal and social constraints. Price floors come from cost and price ceilings from the customer's perception of value; competitors' prices sit between them.

Pricing methods and strategies the paper names
Method or strategyHow the price is setWhen used
Mark-up / cost-plusUnit cost plus a standard mark-upRetail and construction; simple, ignores demand
Target-returnPrice that yields a target return on investment at a forecast volume; uses break-even analysisUtilities, capital-intensive firms
Perceived-valueBased on the buyer's perception of value, not the seller's costDifferentiated and branded products
Going-rateLargely on competitors' pricesOligopolies selling commodities such as steel or paper
Market skimmingHigh initial price, lowered in steps to draw successive price-sensitive layersNovel products with inelastic early demand and patent protection
Market penetrationLow initial price to win share quickly and lower unit cost through volumePrice-sensitive markets with economies of scale and threat of competition
Psychological / odd pricingPrices just below a round figure, or reference prices and prestige pricesConsumer retail
Product-mix pricingProduct-line, optional-feature, captive-product, two-part, by-product and bundling pricesRazors and blades, printers and cartridges, entry fee plus usage

Price adaptation adjusts the list price by geography, discounts and allowances (cash, quantity, functional or trade, seasonal, and allowances such as trade-in), promotional pricing (loss-leader, special-event, cash rebates, low-interest financing, psychological discounting) and differentiated or discriminatory pricing, where the same product is sold at different prices by customer segment, product form, image, channel, location or time. Discriminatory pricing works only where the market is segmentable, the segments show different elasticities, and resale between them can be prevented.

🎯 Why skimming and penetration are opposite bets on the same curve
Skimming assumes the early demand curve is steep — a group of buyers will pay a great deal — so the firm recovers development cost from them first and lowers the price to reach each next layer. Penetration assumes demand is elastic and unit costs fall with volume, so a low price now builds the share that makes the low price profitable later. The paper links skimming to the introduction stage of the PLC with a new, patented product, and penetration to a mass market threatened by imitators.

Key takeaways

  • Five philosophies in order — production, product, selling, marketing, societal; the selling concept starts from the factory and works inside-out, the marketing concept starts from the target market and works outside-in.
  • Four Ps (McCarthy) plus people, process and physical evidence for services; Lauterborn's four Cs are the customer's view; channel levels count the intermediaries between producer and consumer.
  • BCG plots growth against relative share into stars, cash cows, question marks and dogs; Ansoff gives penetration, market development, product development and diversification; segments must be measurable, substantial, accessible, differentiable and actionable.
  • Product mix has width, length, depth and consistency; the PLC runs introduction, growth, maturity, decline, with profit peaking in maturity; new-product development has eight stages from idea generation to commercialisation.
  • Price is the only revenue-producing P; cost sets the floor and perceived value the ceiling; skimming suits a novel patented product with inelastic early demand, penetration a price-sensitive market with scale economies.

Practice questions (9)

Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.

  1. The marketing philosophy that holds consumers will not buy enough of the firm's products unless the firm undertakes aggressive selling and promotion is the:

    1. Selling concept
    2. Product concept
    3. Marketing concept
    4. Societal marketing concept
    Show answer

    Answer: A — Selling concept

    The selling concept starts from the factory and works inside-out, pushing what has been made. The product concept believes quality alone sells; the marketing concept starts from customer needs; the societal concept adds society's long-run welfare.
  2. In the BCG growth-share matrix, a strategic business unit with low market growth and high relative market share is a:

    1. Cash cow
    2. Star
    3. Question mark
    4. Dog
    Show answer

    Answer: A — Cash cow

    Low growth means little investment is needed, and high share means strong cash generation — the cash cow is harvested to fund stars and question marks. Stars are high-high, question marks high growth with low share, dogs low-low.
  3. In Ansoff's product-market grid, selling an existing product in a new geographical market is:

    1. Market development
    2. Market penetration
    3. Product development
    4. Diversification
    Show answer

    Answer: A — Market development

    Existing product plus new market is market development. Penetration is existing-existing, product development is new product in the existing market, and diversification is new-new.
  4. Which of the following is NOT one of the requirements for effective segmentation?

    1. Homogeneous across segments
    2. Measurable
    3. Substantial
    4. Accessible
    Show answer

    Answer: A — Homogeneous across segments

    Segments must be measurable, substantial, accessible, differentiable and actionable. Differentiable means the segments respond differently — they must be heterogeneous across segments and homogeneous within, so 'homogeneous across segments' inverts the requirement.
  5. A company sells soaps, detergents, toothpaste and tea. The number four here measures which dimension of its product mix?

    1. Width
    2. Length
    3. Depth
    4. Consistency
    Show answer

    Answer: A — Width

    Width is the number of product lines. Length counts all items across lines, depth counts variants of each item, and consistency is how closely the lines are related.
  6. In the product life cycle, profits typically reach their peak and begin to decline during:

    1. Maturity
    2. Introduction
    3. Growth
    4. Decline
    Show answer

    Answer: A — Maturity

    Profit is negative or minimal at introduction, rises through growth, peaks early in maturity and then erodes under competition before falling in decline. Maturity is also the longest stage.
  7. Arrange the stages of new-product development in the correct order:
    (A) Business analysis
    (B) Concept development and testing
    (C) Idea screening
    (D) Market testing

    1. C, B, A, D
    2. B, C, A, D
    3. C, A, B, D
    4. B, C, D, A
    Show answer

    Answer: A — C, B, A, D

    The eight stages run idea generation, idea screening, concept development and testing, marketing strategy development, business analysis, product development, market testing, commercialisation. Screening precedes concept testing, business analysis follows it, and market testing comes just before launch.
  8. A firm launches a patented, technologically novel product at a high initial price and lowers it in steps over time. This is:

    1. Market-skimming pricing
    2. Market-penetration pricing
    3. Going-rate pricing
    4. Loss-leader pricing
    Show answer

    Answer: A — Market-skimming pricing

    Skimming takes the top layer of inelastic early demand first and works downward, and suits a protected novel product. Penetration is the opposite — a low price to win share fast. Going-rate follows competitors; loss-leader is a promotional price below cost on one item to draw traffic.
  9. A printer sold cheaply while its ink cartridges carry a high margin is an example of:

    1. Captive-product pricing
    2. By-product pricing
    3. Two-part pricing
    4. Optional-feature pricing
    Show answer

    Answer: A — Captive-product pricing

    Captive-product pricing prices the main product low and the products that must be used with it high — razors and blades, printers and cartridges. Two-part pricing is a fixed fee plus a variable usage fee, as with a telephone connection; by-product pricing prices what the main process leaves over; optional-feature pricing charges for add-ons the buyer can decline.
