Product: design mix, product life cycle and branding
The design mix
Product design balances three competing factors in the design mix:
- Function — does the product do what customers need it to do? Is it reliable, safe, and effective?
- Aesthetics — does it look, sound, or feel appealing? Design and finish matter in markets where appearance drives purchase decisions.
- Cost — can it be produced at a cost that allows a profitable selling price?
The balance shifts by market:
- Budget products emphasise function and low cost (cost leadership).
- Premium/luxury products emphasise aesthetics and function, with cost less constrained.
- Sustainable products now add a fourth element: environmental footprint (e.g. recyclable materials, carbon-neutral production) — increasingly important and examinable at Edexcel.
UK example — Dyson: Dyson products prioritise function (engineering innovation) and aesthetics (distinctive yellow/purple colour palette) at a high cost — they command a price premium. A copycat vacuum emphasises low cost, sacrificing aesthetics and often function.
The product life cycle
Most products follow a predictable life cycle with five stages:
| Stage | Description | Sales | Profit |
|---|---|---|---|
| Development | R&D and testing; no sales yet | £0 | Negative (investment only) |
| Introduction | Product launched; slow growth; high marketing spend | Rising slowly | Often negative |
| Growth | Awareness builds; sales rise rapidly; competitors enter | Rising fast | Becoming positive |
| Maturity | Sales peak; market saturated; competition intense | Peak; slowing | Peak; then declining |
| Decline | Sales fall; product becomes obsolete | Falling | Low/negative |
Cash flow implications: negative in development and introduction, positive in growth and maturity, declining in maturity/decline. Businesses aim to keep products in the profitable maturity stage as long as possible.
Extension strategies
When sales begin to plateau or decline, businesses use extension strategies to prolong the maturity stage:
- New markets: sell the existing product to a new geographic or demographic market.
- Product modifications: update features, design, or packaging (e.g. Diet Coke, Coke Zero, Coke with Coffee — all extensions of the original).
- New promotions: reposition the brand with a fresh advertising campaign.
- Price reductions: attract new, price-sensitive customer segments.
- New distribution channels: e-commerce, partnerships with new retailers.
UK example: Kellogg's Corn Flakes — originally a health food for adults (1906). Extension strategies over the decades repositioned it for children (cartoon mascots), then back to adults (Special K brand split for weight management). The product has been alive for 120 years.
Branding and differentiation
A brand is a name, logo, design, or set of associations that distinguishes a company's products from rivals.
Benefits of strong branding:
- Premium pricing: customers pay more for a brand they trust (Apple, Dyson, Innocent).
- Customer loyalty: repeat purchases without competitive pressure.
- Easier new product launches: brand extension (using an established name in a new category — e.g. Virgin Atlantic → Virgin Money → Virgin Media).
- Reduction in price elasticity: a strong brand means customers are less responsive to price rises.
Differentiation = making a product distinct from rivals in a way that customers value. It can be achieved through: unique features, superior quality, branding, customer service, or design.
