How do designers analyse a case study of an innovation to explain the factors behind its success and its impact on Australian society?
Undertake a case study of an innovation, identifying the factors underlying its success, the ethical issues involved, and its impact on Australian society and the environment
A focused answer to the HSC Design and Technology dot point on the case study of an innovation. The factors underlying success, the difference between invention and innovation, ethical issues, environmental and social impact on Australian society, and how the case study is examined in the written HSC paper.

What this dot point is asking
NESA wants you to undertake a structured case study of a single innovation and use it to explain why that innovation succeeded, what ethical issues it raised, and how it changed Australian society and the environment. This is the analytical half of the HSC written paper, so you need a worked example you can write about under exam conditions.
The answer
Invention versus innovation
The syllabus draws a sharp line between two terms students confuse.
- An invention is the creation of a genuinely new product, system, process or idea. It may never reach the market.
- An innovation is an invention that has been successfully developed, produced and brought into use, usually commercially. Innovation is invention plus exploitation.
Many great inventions failed as innovations because of poor timing, weak marketing or no market need. Your case study must explain not just what was invented, but why it succeeded as an innovation.
Choosing a case study
A good case study innovation is well documented, Australian where possible, and rich enough to discuss across success factors, ethics and impact. Strong choices include the cochlear implant (Cochlear Limited), the Hills Hoist rotary clothesline, the black box flight recorder, wireless LAN (CSIRO Wi-Fi), the Speedo LZR racing suit, Spray-on skin (RECELL), and the plastic banknote (polymer currency). Each is an Australian innovation with a clear emerging technology, a market need and identifiable ethical and social consequences.
Factors underlying success
NESA expects you to analyse the success of the innovation against a consistent set of factors:
- Need or opportunity. Did the innovation solve a real problem or create a new market? The cochlear implant met an unmet medical need for profound hearing loss.
- Emerging technology. Innovation usually rides a new or improving technology. Wi-Fi depended on advances in radio signal processing and integrated circuits.
- Finance and risk. Research and development is expensive. Government grants, venture capital or company reinvestment funded the long development.
- Timing and market readiness. The innovation arrived when the market, infrastructure and price point aligned.
- Marketing and management. Effective promotion, distribution and skilled management converted a good idea into adoption and sales.
- Protection of intellectual property. Patents protected the innovator's investment and allowed licensing income.
Ethical issues
The dot point explicitly requires ethical analysis. For any innovation you should be able to discuss issues such as:
- Intellectual property and patents. Who owns the idea, and were inventors fairly rewarded? CSIRO pursued years of litigation to be paid for the Wi-Fi patent.
- Equity of access. Expensive innovations such as the cochlear implant raise questions about who can afford the benefit.
- Safety and testing. Medical and aviation innovations must balance speed to market against thorough safety testing.
- Cultural and social values. Some innovations are controversial within communities, such as cochlear implants within parts of the Deaf community.
Impact on Australian society and the environment
Finally, evaluate consequences. Social impacts include changes to employment, lifestyle, communication and health. Economic impacts include export income, new industries and skilled jobs. Environmental impacts include resource use, energy consumption, emissions and end-of-life disposal. The polymer banknote, for example, reduced counterfeiting and lasted far longer than paper notes, cutting waste, but raised recycling questions for the polymer substrate.
How it is examined
In the HSC written paper the case study typically appears as an extended response asking you to analyse the factors that contributed to the success of an innovation you have studied, or to discuss its impact on Australian society. Markers reward a named, specific innovation, accurate technical and historical detail, balanced discussion of ethics, and a clear judgement supported by evidence rather than a generic description.
