      Lesson details

      Learning outcome

      I can assess the feasibility and commercial viability of my design.

      Key learning points

      1. Design feasibility assesses whether a product can realistically be made.
      2. Commercial viability assesses whether a product is likely to succeed in the market.

      Keywords

      • Feasibility - the practicality of manufacturing a design

      • Commercial viability - the likelihood that a product can be profitably made and sold

      • Sustainability - designing with consideration for environmental and social impacts

      Common misconception

      If a prototype works, it can definitely be manufactured successfully.

      Functionality doesn’t guarantee feasibility or success. A design might work in one-off form but fail in cost, scale, or sustainability when made commercially.

      Teacher tip

      Use relatable examples (e.g. a well-made student prototype that would be too expensive or complex to produce in volume) to illustrate the gap between workshop making and real manufacturing.

      opinions from others to improve a design

      Q2.
      Which of these shows good design thinking?

      ignoring feedback from people using your product
      Correct answer: trying different ideas to see what works best
      making one design and never changing it
      only thinking about how it looks

      Q3.
      What is the main purpose of a low-fidelity prototype?

      to show the final finishes of a design
      Correct answer: to quickly test and communicate a concept
      to replace all drawings and sketches
      to create a product ready for sale

      Q4.
      Which statement best describes materials used for medium-fidelity prototypes?

      Correct answer: they should be strong enough for testing but easy to shape or adjust
      they must be final, decorative materials ready for production
      they are always made from recycled paper and tape
      they cannot include any mechanical or electronic parts

      Q5.
      What does 'diversity' mean in design?

      creating only one product for everyone to use in the same way
      designing mainly for the average user
      making designs more colourful and stylish
      Correct answer: recognising that users have different needs, priorities, and abilities

      Q6.

      Correct Answer: needs, need

      6 Questions

      Q1.
      Which statement best describes feasibility in design?

      whether a design looks modern and stylish
      Correct answer: whether a design can realistically be made
      whether a design uses only sustainable materials
      whether a design is popular on social media

      Q2.
      Which combination of factors best describes a commercially viable design?

      innovative, colourful, and experimental
      fast, fashionable, and disposable
      expensive, exclusive, and complex
      Correct answer: sustainable, affordable, and in demand

      Q3.
      Designers use a “design for ” mindset to make products easier and more efficient to produce.

      Correct Answer: manufacture, manufacturing

      Q4.
      Why is sustainability important for both feasibility and commercial viability?

      it makes products cheaper to transport
      it guarantees government funding
      Correct answer: it attracts environmentally conscious consumers
      it limits the designer’s creativity

      Q5.
      Match each term to the correct example:

      Correct Answer:feasibility,whether a design could be manufactured in a factory

      whether a design could be manufactured in a factory

      Correct Answer:commercial viability,considering if customers would buy the product

      considering if customers would buy the product

      Correct Answer:sustainability,using recycled or renewable materials to reduce environmental impact

      using recycled or renewable materials to reduce environmental impact

      Q6.
      Which of these best shows the link between inclusive design and commercial viability?

      inclusive products are only made for specialist users
      Correct answer: inclusive designs often appeal to more people, increasing potential sales
      inclusive design makes products more expensive and less marketable
      inclusive design ignores cost and demand
