a) Design mix: function; aesthetics; cost
Every product is a compromise between three pulls, and the model earns its place because it forces a firm to say which one it is selling on. Does the thing work reliably and do the job it is bought for, does it look, feel or taste like something worth owning, and can it be made cheaply enough to leave a margin at the price the market will bear. Dyson sells engineering performance and charges for it, a fast fashion retailer sells appearance and accepts a short product life, and a value grocer's own label is designed backwards from a target cost. The tension is the teaching point, since adding a feature or a finish raises unit cost and only pays where buyers fund it in the price or volume brings the cost down. The triangle says nothing about timing, promotion or how quickly a rival copies the idea.
b) Changes in the elements of the design mix to reflect social trends: concern over resource depletion: designing for waste minimisation, re-use and recycling; ethical sourcing
Rebalancing a product away from lowest cost manufacture and towards durability, repairability and audited supply chains is a repositioning decision rather than a technical one. It is used to defend a premium price and to win shelf space with buyers who screen their suppliers, so the trade off is a higher unit cost now against pricing power and lower regulatory risk later. The Patagonia Worn Wear repair scheme and Adidas trainers built with Parley ocean plastic only work because those customers are insensitive enough to price to absorb the extra cost. Judge it by asking whether the target segment really pays for the claim, whether the sourcing can be verified, and whether thin evidence exposes the firm to accusations of greenwashing that damage the very brand the redesign was meant to strengthen.

Product/service design exam tips
Marking Points
- Names all three pulls and then says which one the case business leads on, with evidence from the extract
- Shows the trade off in money, linking a design change to unit cost, contribution per unit and the price the market will bear
- Connects the chosen emphasis to the target market, so a premium buyer funds performance or finish while a value buyer funds neither
- Evaluates the model by naming what it leaves out, such as promotion, distribution or the speed of imitation
- Naming which part of the design mix gives ground and which gains: economic manufacture yields to longevity, recyclable materials and audited sourcing.
- Applying the change to the named product and its customer, such as a repairable jacket sold to a segment that already pays a premium, rather than describing recycling in general.
- Directing the cost effect, for example a rise in unit cost that narrows contribution per unit unless the selling price moves with it.
- Weighing brand and compliance benefits against cost and reaching a supported judgement on whether the redesign suits this business in this market.
Examiner Tips
- 💡Short items ask you to outline one element for a named product, so give the element and one piece of case evidence rather than a tour of all three
- 💡Longer items want the trade off argued and judged, so end on whether the target customer will pay for the element the firm is adding
- 💡This arrives as an analyse or assess item on a case study product, so build two linked chains of reasoning from the stem instead of a list.
- 💡The evaluation marks come from a condition: say when the redesign pays off, usually a differentiated brand, inelastic demand and buyers who audit suppliers.
- 💡Take one figure from the case evidence, such as a unit cost or a market share, and use it, because unsupported assertion caps the level awarded.
Common Mistakes
- Describing the three elements in the abstract and never saying which one dominates for the named product
- Assuming better design always costs more, when standardising parts or redesigning for manufacture can cut cost and improve function at the same time
- Treating appearance as the only aesthetic, when smell, taste, sound and feel carry the same weight in food and audio products
- Listing all three parts of the design mix as a memorised triangle and never saying which one the social trend actually squeezes.
- Assuming every customer will pay more for a greener product, when a price sensitive segment with many substitutes simply buys the cheaper rival.
- Treating an environmental claim as automatically good publicity and ignoring the backlash when the claim turns out to be unverified.
