Product and Branding
The marketing mix is the tactical layer that executes the strategy STP set, and Product is its first and most consequential element — everything else prices, distributes and communicates the product. This chapter treats product and brand as a chain of managerial decisions. It opens with the 7Ps and the unit's distinctive “cake” framing (the Ps are interdependent ingredients — change one and mind the rest), then peels every offer into five product layers, diagnoses a portfolio with width / length / depth / consistency, and manages it via line stretching, filling and flanker brands. It places a product on the Product Life Cycle and prescribes the right 4P moves per stage, maps a launch onto Diffusion of Innovation, then turns to the brand: aligning brand identity (sent) with brand image (received), building equity bottom-up with Keller's Brand Resonance Pyramid, and auditing cues with the Distinctive Assets Grid (Sharp & Romaniuk).
What this chapter covers
- 01P1 The 7Ps and the "cake" interaction model
- 02P2 The 5 product layers (core → basic → expected → augmented → potential)
- 03P3 The product mix — width, length, depth, consistency
- 04P4 Line decisions — stretching, filling, flanker brands
- 05P5–P6 The Product Life Cycle + strategy matrix; Diffusion of Innovation
- 06P7–P9 Brand identity vs image; Keller's Resonance Pyramid; the Distinctive Assets Grid
Worked example: diagnose the PLC stage and prescribe the 4P moves
- +1Read the signals: sales rising fast, profit peaking, competition growing → the product is in the Growth stage; the objective is to maximise market share.
- +1Product: extend the line and add features/variants to broaden appeal and stay ahead of imitators.
- +1Price: hold or selectively cut to drive penetration and win share while demand is expanding.
- +1Place: move to intensive distribution — get it into far more outlets to capture the surging demand.
- +1Promotion: shift from pure awareness to building the brand in the mass market and stressing preference over rivals.
- +1Sense-check with diffusion: Growth is driven by the early adopters and early majority — the make-or-break gap is crossing into the early majority.
Key terms
- The 7Ps (the "cake")
- Product, Price, Place, Promotion + People, Process, Presence (physical evidence). The unit's cake framing: the Ps are interdependent ingredients, so change one P and there are implications for the rest — consistency of the whole mix beats brilliance in any one P.
- The 5 product layers
- Core benefit → basic → expected → augmented → potential. Each is a place to differentiate; most mature categories compete almost entirely at the augmented layer.
- Product mix
- The firm's portfolio, described on four dimensions: width (number of lines), length (total items), depth (variants per item), and consistency (how related the lines are). Managed via stretching, filling and flanker brands.
- Product Life Cycle (PLC)
- The S-curve of sales through Introduction → Growth → Maturity → Decline. Each stage faces different competition and buyers, so each needs a different 4P strategy; diffusion of innovation drives the curve.
- Keller's Brand Resonance Pyramid
- A bottom-up model of brand-building in four tiers / six blocks: Salience (who are you?) → Performance & Imagery (what are you?) → Judgments & Feelings (what about you?) → Resonance (how strong a bond?). You cannot skip tiers.
Product and Branding FAQ
What is the "cake" model and why does it matter?
It's the unit's framing that the 7Ps are interdependent ingredients, not a checklist: change one P and there are implications for the others (a premium price demands a premium product, selective place and prestige promotion). A mismatched mix tastes wrong however good each ingredient is, and Part B is marked on whether every mix decision traces back to the positioning.
Stretching vs filling vs flanker brands — what's the difference?
Stretching changes the range (a new price/quality point — down-market, up-market like Toyota→Lexus, or two-way). Filling adds items inside the existing range to plug gaps. A flanker (fighter) brand uses a different brand name to shield the flagship from a price war or new segment — a sub-brand shares the parent name and so does not protect it.
How do the PLC and Diffusion of Innovation connect?
Diffusion drives the PLC: each adopter wave maps to a stage. Innovators (2.5%) and early adopters (13.5%) fuel Introduction–Growth; the early and late majority (34% each) are Maturity; laggards (16%) are Decline. Crossing from early adopters to the early majority is the make-or-break gap.
What's the difference between brand identity and brand image?
Identity is the signal the firm intends to send (name, logo, slogan, colour — the brand elements). Image is how the market actually perceives the brand. The managerial task is alignment: a gap between intended identity and received image is a positioning failure to fix via comms, experience or repositioning.
Exam move
Product/brand is examined as applied frameworks, so drill the application, not the labels. Be ready to classify a real offer into the 5 layers; diagnose a portfolio on width/length/depth/consistency and recommend one directional move; place a product on the PLC and prescribe the fitting 4P moves (memorise the objective per stage); map a launch onto the Diffusion curve and find the early-majority gap; and audit a brand with Keller's Pyramid (bottom-up — you cannot skip tiers) or the Distinctive Assets Grid (fame × uniqueness → invest / use / ignore / avoid). In Part B, your ‘Product’ recommendation must name the layer you are augmenting and the PLC stage you are managing — and trace back to the positioning.
