Project development and realisation: HSC Design and Technology Designing and Producing
“Document project development and realisation, including research, idea generation and development, experimentation, modelling, and the safe and skilful production of the final solution”
Project development and realisation is the core folio section documenting how the brief became a finished solution. It records research, divergent then convergent idea generation, experimentation and modelling, the selection and testing of materials and processes, and the safe, skilful production of the final product, system or environment. It must show visible iteration, decisions justified against the criteria, and quality control throughout.

What this dot point is asking
NESA wants you to document the development and realisation of your Major Design Project, the largest section of the folio and the one carrying the most marks. This covers everything between the proposal and the evaluation: research, generating and developing ideas, experimenting and modelling, and finally producing the solution safely and skilfully. Markers want to see a genuine, iterative process.
The answer
Research that informs development
Development begins with focused research: user and market research, properties and cost of materials and components, ergonomic and anthropometric data, relevant standards and existing solutions. Research is not a tick box; it should be referenced and then visibly used to justify decisions. A folio that researches a material and then explains why it was chosen scores far better than one that lists facts in isolation.
Generating and developing ideas
Idea generation uses divergent thinking to produce many possibilities through sketching, brainstorming, mind mapping and mood boards. Development then uses convergent thinking to refine, combine and select the strongest concepts, each tested against the criteria to evaluate success. This is the most iterative part of the project, and the folio should show the dead ends and how they were resolved, not just the winning idea.
Experimentation and modelling
Before committing to the final solution you test ideas through experimentation and modelling:
- Material and process trials, checking that a joint, fabric or finish performs as needed.
- Models and prototypes, physical or digital, that make a concept testable.
- Computer aided design, used to visualise, simulate and refine before production.
Each test feeds back into development. A prototype that fails sends you back to refine the idea, which is the iteration markers reward.
Selecting materials, components and processes
The chosen solution requires deliberate selection of materials, components, tools and production processes, justified against function, cost, availability, safety, sustainability and the criteria. Documenting why each choice was made, with reference to research and testing, demonstrates the informed decision making the syllabus values.
Realisation: producing the solution
Realisation is the safe, accurate and skilful production of the final product, system or environment. The folio documents the production sequence with dated photographs, records quality control checks against the criteria at each stage, and shows that work health and safety practices were followed. Skilled, safe production is directly assessed, so evidence of competent technique and quality control is essential. The finished solution is judged on quality, creativity and fitness for the identified purpose.
How NESA marks this section
In the three part folio structure, development and realisation carries the largest share of the project marks because it captures the bulk of the design and production work. Markers look for evidence of a genuine iterative process, justified decisions, skilful production and quality control, all referenced back to the brief and criteria. Confirm the current mark allocation against NESA project advice.
Why this matters in the HSC
This section is where the project is won or lost. A folio that presents a single straight path to a perfect result looks reconstructed and scores poorly; one that documents research, multiple ideas, testing, refinement and skilful production across the year demonstrates the design process in action. Continuous dated documentation, including photographs of production, is what proves the work is genuinely yours.
A student is developing a desk organiser and wants the development-and-realisation section to evidence a genuine iterative process.
Step 1: Apply research to the brief
Summarise the relevant research (user needs, material properties, existing organisers) and reference it, then state how it shapes the requirements.
Step 2: Diverge, then converge on ideas
Present several annotated concepts from sketching and mind mapping (divergent), then refine and select the strongest against the criteria to evaluate success (convergent), keeping the rejected ideas in the folio.
Step 3: Experiment and model
Run material and process trials and build a prototype (physical or CAD). Record what each test showed; if a joint fails, document the change made and re-test.
Step 4: Justify materials and processes
Select materials, components and processes and justify each against function, cost, availability, safety, sustainability and the criteria, citing the trials and research.
Step 5: Realise and control quality
Produce the final solution with dated production photographs, safe operating procedures and PPE, and quality-control checks against the criteria at each stage, ending with the finished organiser verified against the brief.
Development and realisation is the largest marked section of the Major Design Project folio, so the bulk of project marks reward documented iteration, justified decisions and skilful, safe production rather than a polished final image alone.
- Showing only the winning idea
- Document multiple concepts, testing and the dead ends to prove genuine iteration.
- Listing research without using it
- Reference research and then show how it justified a decision.
- Neglecting quality control and WHS
- Record checks against criteria and safe practice throughout production, not just the finished item.
- Reconstructing the folio at the end
- Continuous dated documentation and production photographs prove the process was real.
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.
HSC 2022-style3 marksDistinguish between divergent and convergent thinking in the development of design ideas, and explain where each is used.Show worked answer →
Divergent thinking generates many possibilities, deliberately widening the field of ideas through sketching, brainstorming, mind mapping and mood boards; it is used early in idea generation to avoid settling on the first concept. Convergent thinking then narrows the field, refining, combining and selecting the strongest concepts and testing each against the criteria to evaluate success; it is used in development to reach a resolved solution. Markers reward a clear definition of each, the contrast (widening versus narrowing), and the placement of each within the development process.
HSC 2024-style6 marksEvaluate the importance of experimentation and modelling to the successful realisation of a Major Design Project.Show worked answer →
A strong response argues that experimentation (material and process trials) and modelling (physical or digital prototypes, CAD) let a designer test ideas before committing expensive materials and time to the final solution, reducing risk and improving quality. Each test feeds back into development: a prototype that fails sends the designer back to refine the idea, producing the documented iteration that markers reward. The evaluation should weigh the cost (trials and prototypes take time and resources) against the benefit (problems are found and fixed cheaply, the final solution is more likely to be fit for purpose, and the folio gains strong evidence of process). A top answer concludes that experimentation and modelling are central to realisation, supported by an example such as testing a joint before building the frame. Markers reward a sustained judgement, not just description.
