      Commercial viability: saving space

      Lesson details

      Learning outcome

      I can identify and understand the factors in making products commercially viable.

      Key learning points

      1. Commercial viability is whether a product can be made, sold, and make a profit in the real world.
      2. Commercial viability helps businesses make decisions about materials, manufacturing, pricing, and marketing.
      3. It ensures the product is realistic, meets customer needs, and can compete with similar products in the market.

      Keywords

      • Commercial viability - the likelihood of a product being successful in its target market and making a profit

      • Profit - the money a business earns after paying all its costs

      • Target market - the specific group of people a product is designed and sold for

      Common misconception

      Commercial viability only relates to how well a product works.

      A product can work well or be aesthetically pleasing, but if it’s too expensive to make, doesn’t meet market demand, or won’t sell at a profit, it isn’t commercially viable.

      Teacher tip

      Use real-life product case studies (e.g., successful and unsuccessful products) to show students how good design doesn’t always mean commercial success. Discuss factors like cost of production, target market, pricing, and demand.

      Equipment

      Examples of successful and unsuccessful products.
