The Design Mix: Function, Aesthetics and Cost
The design mix is a model used to balance three considerations when designing a product: function, how well it does its job; aesthetics, how it looks and feels; and cost, how much it costs to produce and therefore how it can be priced.
Before you start
Make sure you're comfortable with these topics first:
Method
- Learn the definition of each of the three elements and be able to give an example decision under each.
- Learn that the three elements pull against each other: increasing function or aesthetics usually increases production cost, which then affects the price the business must charge to maintain its profit margin.
- Learn how the right balance depends on the target market and product type: a budget product for a price-sensitive segment should emphasise low cost even if this limits aesthetics or function; a luxury or safety-critical product should emphasise function or aesthetics even at higher cost.
- Practise applying the design mix to a specific product in a case study: identify which element the business seems to be prioritising from the details given, such as materials, price or target market, and whether this fits its market.
- For 'explain' questions, name the design mix element plus the linked trade-off or benefit for that specific business or product.
- For 'recommend' or 'evaluate' questions, weigh the three elements against the case's target market, price point and competition, then reach a supported judgement.
Worked example
Kingfisher Kitchenware is designing a new frying pan. Option A uses a basic non-stick coating and a simple plastic handle, costing 4 pounds to produce and expected to sell for 12 pounds. Option B uses a premium ceramic coating, a stainless steel handle and a more ergonomic shape, costing 11 pounds to produce and expected to sell for 28 pounds. Kingfisher's target market is budget-conscious shoppers at discount homeware stores. Recommend which option better fits the design mix for this target market, with a reason.
- Identify each option's emphasis: Option A prioritises low cost, with function and aesthetics kept basic; Option B prioritises function, through the ceramic coating and ergonomic shape, and aesthetics, through the stainless steel handle, at a much higher cost.
- Consider the target market: budget-conscious shoppers at discount homeware stores are likely to be highly price-sensitive and prioritise low cost over premium features or appearance.
- Consider whether Option B's higher price of 28 pounds fits this market: a price more than double Option A's is unlikely to appeal to shoppers specifically choosing a discount homeware store.
- Consider Option A's fit: its lower cost allows a lower price of 12 pounds that matches what budget-conscious shoppers at a discount store expect to pay, even though its function and aesthetics are more basic.
- Recommend Option A, because Kingfisher's target market prioritises low price over premium function or aesthetics, and Option A's design mix, emphasising cost, is better matched to this specific customer group and retail channel.

Q1Name the three elements of the design mix.Show answer
Answer: Function, aesthetics and cost.
Q2What does 'function' mean in the design mix?Show answer
Answer: How well a product performs the job it is designed to do, such as its performance, reliability or safety.
Q3Give one example of an aesthetic feature of a product.Show answer
Answer: Its colour, shape, texture, or overall visual appearance (any one).
Q4Why does increasing a product's function or aesthetics usually increase its cost?Show answer
Answer: Because improving performance or appearance typically requires better materials, more complex manufacturing, or additional features, all of which raise the cost of production.
Q5A product for a safety-critical use, such as a car brake pad, should prioritise which element of the design mix, and why?Show answer
Answer: Function, because reliability and safety are essential to the product doing its job, even if this increases cost.
Q6State one reason a business selling in a highly price-sensitive, budget market might deliberately limit a product's aesthetics.Show answer
Answer: To keep production costs low, so the product can be sold at a low price that fits what budget-conscious customers are willing to pay.
Q7True or false: the correct balance of the design mix is the same for every product.Show answer
Answer: False - the appropriate balance depends on the target market, the product's use and the business's objectives.

Harlow Cycles designs bicycles for two ranges: an entry-level commuter bike and a premium road bike. It is deciding whether to fit the same lightweight carbon-fibre forks, which significantly improve performance but add 60 pounds to production cost, to both ranges or only to the premium range. Evaluate whether Harlow Cycles should fit the carbon-fibre forks to its entry-level commuter bikes.
