The Marketing Mix: Product & Price (Years 9–11) — Business Studies

The 4 Ps overview, product design and the product life cycle, plus pricing methods such as cost-plus and skimming.

The marketing mix is the set of decisions a business makes to sell a product successfully, often called the 4 Ps: Product, Price, Place and Promotion.

Why this matters The 4 Ps must work together. A well-designed product at the wrong price, or in the wrong place, will still fail. Getting the mix right turns a good idea into steady sales.

Product

The product must meet a customer need and have a clear unique selling point (USP) a reason to choose it over rivals, such as gentle, natural ingredients in a halal snack. Good design considers quality, features, packaging and safety.

The product life cycle

Most products pass through stages:

Introduction: launch, low sales, heavy promotion.
Growth: rising sales as awareness spreads.
Maturity: sales peak; strong competition.
Decline: sales fall.

To lengthen a product's life, firms use extension strategies such as new flavours, fresh packaging or new markets.

Sales typically rise through introduction and growth, plateau at maturity, then fall in decline — an extension strategy lifts sales again before that fall.

Pricing methods

Method	How it works
Cost-plus	Add a percentage profit to the unit cost.
Competitive	Set price in line with rivals.
Penetration	Start low to win customers, then raise later.
Skimming	Start high for a new, in-demand product, then lower it.

Choosing a method

The best method depends on costs, competition and the type of product. A new tutoring app might use penetration pricing to attract users quickly, while a unique new gadget might use skimming. Honest pricing, with no hidden charges, builds trust and repeat custom.

Put these stages of the product life cycle in order:

Introduction — launch, low sales, heavy promotion
Growth — sales rise as awareness spreads
Maturity — sales peak and competition is strong
Decline — sales fall

Common exam mistake: describing maturity as a stage where sales are "still growing fast". In maturity, sales have peaked and level off — it is growth, not maturity, where sales rise strongly. Mixing these two up is one of the most frequent errors on this topic.

Exam technique: when recommending a pricing method, name the specific feature of the case-study product that justifies it — genuinely new and unique suits skimming, needing to break into a crowded market fast suits penetration, and a product very similar to rivals suits competitive pricing.
