Component 1: Marketing – Product — Eduqas A-Level Business

A product is anything sold to satisfy a need, a portfolio is the full set of products one firm sells, and the remaining terms are about standing out: the one feature rivals cannot match, the wider job of making the whole offer distinct on quality, design, service or image, and the name and associations that carry both. The business use is pricing power, because a distinctive offer makes demand less price elastic, so the firm can raise price with a smaller fall in quantity demanded. Porter treats distinctiveness as one of the generic strategies but is blind to how fast a feature is copied, and a range spread over unrelated items scatters marketing spend. Dyson's cyclone technology is a checkable example of a feature rivals could not legally match.

Everything else in the mix depends on what is being sold, because promoting something customers do not want only speeds up the discovery, and this is examined as a judgement question with named interest groups. Owners care about margin and return on capital employed, employees about job security and hours, suppliers about steady order volumes, customers about quality against price, and the local community about the firm surviving at all. The judgement usually lands on fit rather than quality in the abstract, since a technically superb item aimed at the wrong segment still fails, which is what happened to Google Glass. Argue the other side too, because strong distribution, a low price or a trusted name can carry an average offer for years, which is why supermarket own label ranges sell so well.

The product life cycle tracks the stages a product passes through from development to withdrawal: research and development, introduction, growth, maturity, and decline. Each stage features distinct sales volumes, cash flows, and marketing challenges. Introduction involves negative cash flow and high promotion costs; growth sees rising sales and unit cost economies; maturity reaches peak sales with intense competition; and decline experiences falling demand and discounting pressures unless extended.

Five phases are examined. Development, where money goes out and sales are zero. Launch, with slow sales, negative cash flow and a choice between skimming and penetration pricing. Growth, where sales accelerate, unit costs fall through economies of scale and rivals arrive. Maturity, the longest and most profitable phase, where promotion defends share and price competition bites. Then decline, where sales and contribution fall and the firm chooses between extension, harvesting and withdrawal. The teaching point is that each phase demands a different mix and a different cash position, so a firm with several fast growing lines at once faces a cash squeeze even while sales look healthy. Naming where the case product sits unlocks every later argument.

When sales flatten or begin to slide, a firm can act to lengthen the profitable life of something it already sells rather than spend on a replacement, and the recognised tactics are new markets or exports, new uses, changed packaging or format, price cuts, product updates and fresh promotion. The commercial logic is that development cost is already sunk, so extra sales carry a high contribution per unit, which is selling price minus variable cost per unit. Lucozade moving from a drink for the sick to a sports drink is the standard checkable example. The trade off is that this can delay genuine innovation, and a price cut lifts revenue only where demand is price elastic, so the firm should test elasticity before assuming that revenue rises.

A product life cycle diagram plots sales volume on the vertical axis against time on the horizontal axis, displaying the classic S-shaped curve through introduction, growth, maturity, and decline. Profit typically peaks during the late growth or early maturity stage before sales peak, as competitive pressures compress margins. Extension strategies—such as product reformulation, rebranding, entering new markets, or altering packaging—are shown as secondary upward curves during maturity that delay decline.

Judging these tactics means weighing extra revenue and cash from something whose development cost is already recovered against the cost of the relaunch, the risk to brand image and the opportunity cost of not developing anything new. Argue with numbers where the case gives them, since extra units multiplied by contribution per unit set against promotional spend gives a rough payback on the tactic, and the payback period is the time taken for net cash inflows to cover the outlay. It suits a firm with a strong name in a market still large enough to serve, which is why Kit Kat keeps adding flavours. It suits a firm badly where the underlying technology is obsolete, because no repackaging rescues something customers no longer need, as the compact disc showed.

Cash and profit move at different speeds across development, launch, growth, maturity and decline, and the marks come from applying that gap to a named firm. Development and launch consume cash before a single unit is sold, so net cash flow is negative while research, tooling and launch promotion are being paid for. Growth narrows the deficit as volume rises faster than promotional spend, maturity is normally when net cash inflow peaks because unit costs are low and marketing has become maintenance rather than launch, and a declining product still generates cash for as long as revenue covers its variable costs. The portfolio argument follows: a mature seller such as Kellogg's Corn Flakes funds the next launch, so a firm whose products are all young needs an overdraft or investor money, not better advertising.

An extension strategy is any action that lifts sales before decline takes hold, and the marks come from choosing one that fits the product, the market and the firm's resources. The standard menu is new packaging or formats, a new target market or country, a price change, modification of the product itself, promoting a new use, and heavier promotion, and each maps onto Ansoff, since modification is product development while a new country is market development. Cycle shapes differ sharply. A fad toy peaks in months, a fashion item runs a season, a staple such as Heinz Baked Beans has sat in maturity for decades, and a smartphone model is deliberately retired by its own successor. Analysis means tracing the chain from the chosen action to volume, to unit cost and to brand perception.

The product life cycle assists management in planning cash flow, timing new product launches, and adjusting marketing mixes across a portfolio. However, its predictive power is limited: stage durations are unpredictable, external shocks disrupt trends, and treating decline as inevitable risks creating a self-fulfilling prophecy where cutting marketing budget causes the sales drop. Stakeholders face differing impacts, as shareholders require balanced portfolio returns while employees face redundancy during decline.

The grid plots every product on two axes, relative market share and market growth rate, and sorts them into cash cows, stars, question marks and dogs. Relative market share is the product's share divided by the share of the largest rival, so a value above one signals market leadership, while growth rate is the annual percentage increase in the size of the whole market, with about ten per cent the conventional dividing line. The management use is routing cash. Cows in slow growth markets throw off surplus, that surplus funds stars which need investment simply to hold share in a fast growing market, question marks are either backed hard or dropped, and dogs are divestment candidates. It also tests balance, since a portfolio of only cows has no future and one of only question marks has no funding.

The grid is a snapshot built from two variables, and everything it leaves out is where the judgement marks sit. It ignores profit margin, so a dog can earn more than a star; it ignores the links between products, so dropping a loss making line can lose the customers who bought the profitable one alongside it; and the market boundary is drawn by the firm itself, which can flatter its own share by defining the market narrowly. It also assumes high share brings low cost through the experience curve and that high growth is attractive, when fast growing markets attract entrants and price competition. Set against that, it forces a resource allocation conversation and works well beside the life cycle. The verdict usually depends on how reliable the market data is and how often the grid is refreshed.
