Who is an end-user, who are the wider stakeholders, and how does designing for real people rather than yourself change every decision in the folio?
the role of the end-user and stakeholders in user-centred design, and how investigating their needs, wants, preferences and constraints drives the design brief and the product
A VCE Product Design and Technologies Unit 3 answer on user-centred design: who the end-user and stakeholders are, how to investigate their needs, wants and preferences, and how those findings drive the brief and the whole School-Assessed Task.

What this dot point is asking
This dot point sits at the start of the design half of the subject. Before you can write a brief or sketch an idea, you have to know who you are designing for. Getting this right makes the rest of the folio coherent; getting it vague makes everything downstream weak.
End-user versus stakeholder
These two terms are not interchangeable, and the exam tests the difference.
- End-user. The specific person (or defined group) who will actually use the finished product. They have measurable needs, a body, a context and preferences.
- Stakeholders. Anyone else affected by or interested in the product: the person who pays for it, retailers who sell it, the people who manufacture it, regulators, and the wider community or environment that bears its impact.
Needs, wants and preferences
Investigating the end-user means separating three things that students often blur. A need is essential to the product's function (a chair must bear weight). A want is desirable but not essential (the chair folds flat for storage). A preference is about taste (the end-user likes pale timber). Strong folios label these clearly, because needs become non-negotiable constraints in the brief while wants and preferences guide refinement and selection.
How investigation drives the design
The point of investigating the end-user is not to fill folio pages; it is to generate the constraints and considerations that the brief will list and the evaluation criteria will test. Anthropometric data (the end-user's measurements) sets dimensions. Their environment sets size, weight and material limits. Their stated frustrations define the problem. Their preferences guide aesthetics. Every later decision should be traceable back to a finding about the end-user or a stakeholder requirement.
Investigation methods and ethics
You gather end-user information through interviews, surveys, observation and measurement, combining qualitative insight (what they say and feel) with quantitative data (dimensions, frequencies). When you involve real people you respect their privacy, seek consent and represent their views honestly. Treating the end-user as a genuine collaborator, not a prop, produces better evidence and better products.
When you can distinguish the end-user from stakeholders, separate needs from wants and preferences, and show that every brief constraint traces to a genuine finding about a specific person, you have met this dot point and given the whole School-Assessed Task a defensible foundation.
Exam-style practice questions
Practice questions written in the style of VCAA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
2025 VCAA5 marksA home office chair was evaluated in a user trial. A design can be improved or enhanced in response to feedback from end users. Based on the information provided, identify two areas in which the design of the home office chair could be improved or enhanced, and justify one of the areas identified using the results from Graph 1 and Graph 2.Show worked answer →
This combines parts a and b of a 5 mark question: 2 marks for identifying two improvement areas, 3 marks for justifying one using the graph data.
Identify two areas (2 marks, 1 each). Choose features the end users rated less favourably or were unlikely to select, for example the fabric (rated lower than style in Graph 2) and the style or visual appeal that 25 of 50 participants were unlikely to select in Graph 1. Other defensible areas include comfort, adjustability or aesthetic fit with a home office.
Justify one area using the data (3 marks). Pick one area and tie it to the figures. For example: the fabric should be improved because Graph 2 shows it was rated lower overall than style, and Graph 1 shows 25 of 50 participants were unlikely to select the chair on its current visual features. Improving the fabric directly targets the weakest-rated feature, so it should lift end-user satisfaction and the likelihood of selection.
Full marks require the justification to quote or reference the actual results, not just assert that the change would help.
2025 VCAA3 marksThe factors that influence product design are also used to evaluate a product. One of those factors is end users. Add a total of three annotations to the visualisations to highlight features of the chairs that are relevant to the end user.Show worked answer →
Three marks, one for each annotation that genuinely links a visible feature of the chair to an end-user need. In a written response, describe the three annotations you would add.
Each annotation should name a feature and explain its relevance to the end user, for example:
- Adjustable seat height so the chair suits end users of different statures working from home.
- Lumbar or back support to keep a home worker comfortable and reduce strain over long periods.
- Breathable fabric or armrests improving comfort and usability for the daily home-office user.
Markers reward annotations that connect form to the end user (comfort, ergonomics, adjustability, accessibility), not generic labels such as the colour or material with no user link.
