How does the project development and realisation section document the research, idea development and production that turn a brief into a finished solution?
Document project development and realisation, including research, idea generation and development, experimentation, modelling, and the safe and skilful production of the final solution
A focused answer to the HSC Design and Technology dot point on project development and realisation, the largest folio section. Documenting research, idea generation and development, experimentation and modelling, selection of materials and processes, and the safe, skilful production of the final product, system or environment.

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.

HSC 20223 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.

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.
