What this dot point is asking
This dot point grounds design in commercial reality. Every product is made within a budget and sold at a price, and economic factors recur in exam questions and in your own folio's costings and material choices.
The main economic factors
Several money-related forces shape every design.
- Cost of materials and processes. Different materials, finishes and manufacturing methods cost different amounts, directly affecting design choices.
- Budget. The funds available, whether a client's budget or a price the market will bear, capping what can be specified.
- Scale of production. Volume changes unit cost; tooling that is too expensive for a one-off becomes economic at mass scale.
- Market demand and viability. Whether enough people will buy the product at a price that covers costs and returns a profit.
Balancing cost against quality and other factors
Economic factors rarely act alone; they trade off against the other design factors. A cheaper material may weaken function or sustainability; a premium finish may exceed budget. The designer's job is to find the balance that meets the brief and the end-user's needs within the money available, and to justify where they spent and where they saved.
Costing in your folio
Your scheduled production plan includes a materials and costings list, so economic factors are not abstract; you price your own design. Working out what materials, fittings and finishes cost, staying within a realistic budget, and noting where a cheaper alternative was rejected for quality reasons all demonstrate economic awareness. This costing feeds the later evaluation of efficiency.
Economic factors and sustainability
Economic and environmental factors often pull together or against each other, and the mature view holds them in tension. Durable, repairable products may cost more upfront but save money and waste over their life; the cheapest material may carry hidden environmental and social costs. Discussing cost alongside life cycle thinking, rather than treating money and sustainability as separate, shows the integrated judgement the subject expects.
When you can identify the economic factors, explain how designers balance cost against quality and the other design factors, and apply costing and value thinking to your own product, you have met this dot point and grounded your design in commercial reality.
