The design process: HSC Design and Technology Designing and Producing
“Apply the design process to develop a quality solution, including identifying needs, research, generating and developing ideas, planning, producing and ongoing evaluation”
The design process is an iterative sequence for turning an identified need into a realised product, system or environment: identify the need and write a brief with criteria, research, generate and develop ideas, plan and produce the solution, and evaluate continuously throughout. It is not linear; designers loop back to earlier stages as testing reveals new information.

What this dot point is asking
NESA wants you to apply the design process as a structured, iterative method for developing a quality solution to an identified need. You must know each stage, why it matters, and how the stages loop back through ongoing evaluation. This process is the backbone of your Major Design Project folio.
The answer
Identifying needs and opportunities
Every project begins with a genuine need or opportunity. A need is a problem to be solved; an opportunity is a gap in the market or an improvement waiting to be made. You identify these through observation, user research, surveys and analysis of existing products. The clearer the need, the stronger the eventual judgement of success.
The design brief and criteria to evaluate success
The need is formalised in a design brief, a short statement of the problem, the intended user, constraints and requirements. From the brief you derive criteria to evaluate success, a measurable checklist (function, aesthetics, ergonomics, cost, safety, sustainability, durability) against which every later decision and the final solution are judged. These criteria are central to the HSC because evaluation must always refer back to them.
Research
Research gathers the information needed to design well. It covers:
- User and market research, who will use the product and what competitors exist.
- Material and component research, the properties, cost and availability of options.
- Ergonomic and anthropometric data, ensuring the solution fits the human body.
- Technical and safety research, including relevant standards and regulations.
Good research is documented and referenced in the folio so decisions are evidence-based.
Generating and developing ideas
Idea generation uses divergent thinking to produce many possibilities through brainstorming, mind-mapping, sketching, mood boards and lateral thinking. Development then uses convergent thinking to refine, combine and select the strongest ideas, testing them against the criteria. Modelling, prototyping and computer-aided design turn rough concepts into testable solutions. This is the most iterative part of the process.
Planning and managing production
Before producing, you plan: a production schedule (often a Gantt chart), a materials and equipment list, a finance plan and a risk and safety assessment. Planning converts the chosen design into an achievable sequence of tasks within time and budget. Work health and safety considerations and quality control checkpoints are built in here.
Producing the solution
Production realises the design as a physical or digital product, system or environment. You apply appropriate materials, tools, techniques and finishes, maintaining quality control against the criteria at each stage. Skilled, safe and accurate production is directly assessed in the Major Design Project.
Ongoing evaluation
Evaluation is not a final step bolted on at the end. It runs throughout, comparing each decision against the criteria and feeding back into earlier stages. This iteration is what makes the design process a cycle rather than a line. A prototype that fails a test sends you back to develop a better idea. Final evaluation judges the completed solution against the original criteria and reflects on the process itself.
Why iteration matters in the HSC
The Major Design Project folio must show evidence of this iterative process, not just a finished product. Markers look for documented decisions, testing, feedback and refinement. A folio that records dead ends and how they were resolved scores higher than one that presents a single straight path to a perfect result.
Criteria to evaluate success are written at the briefing stage and used at every later stage, making them the single thread that connects identifying the need to the final evaluation in the Major Design Project.
- Treating the process as linear
- The design process loops. Show evidence of returning to earlier stages after testing.
- Vague or missing criteria
- Without measurable criteria you cannot justify decisions or evaluate the result.
- Under-documenting development
- The folio rewards visible iteration, sketches, prototypes, tests and feedback, not just a polished final design.
- Skipping planning
- A production schedule and risk assessment are assessable and prevent the project running out of time.
Exam-style questions
Questions in the style of NESA exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
2022 HSC-style2 marksOutline how testing and experimenting can improve a design project.Show worked answer →
For 2 marks, identify a benefit of testing and experimenting and show how it improves the project.
Testing and experimenting let the designer explore the successes and failures of different materials, tools and techniques before committing to a final solution. Trialling ideas reveals flaws or weaknesses early, while there is still timely opportunity to adjust and refine the design.
Make the link to improvement explicit: catching problems during development saves time, money and material wastage, and the evidence gathered justifies design decisions against the criteria to evaluate success. A response that only states that designers test, without showing how this improves the project, sits at 1 mark.
2023 HSC-style1 markWhat is the primary purpose of ongoing evaluation? A. To set goals B. To explore ideas C. To establish consumer needs D. To solve design issues as they ariseShow worked answer →
The correct answer is D, to solve design issues as they arise.
Ongoing evaluation runs throughout the design process rather than only at the end. Its purpose is to test each decision against the criteria to evaluate success and to identify and resolve problems as they emerge, feeding the results back into earlier stages. This is what makes the design process iterative rather than linear.
A is wrong because goals are set when identifying the need and writing the brief. B is idea generation, an earlier stage. C, establishing consumer needs, happens during research at the start, not as part of continuous evaluation.
