Question 1Design and the design process

A designer evaluates a prototype against the design brief and finds several unmet criteria. Which stage of the design process does this activity most directly belong to?

  1. Implementation
  2. Ideation
  3. Evaluation Correct answer.
  4. Research

Explanation

Evaluation compares the developed solution back to the original brief, constraints and criteria to judge how well needs are met. It typically follows prototyping and testing, and its findings feed into refinement or redesign decisions.

Question 2Design and the design process

Which term describes a fixed limit on a design, such as a maximum budget or a required product mass?

  1. Criterion
  2. Function
  3. Aesthetic
  4. Constraint Correct answer.

Explanation

A constraint is a non-negotiable boundary the design must work within, such as cost, materials, size or legal requirements. Criteria, by contrast, are the qualities used to judge how successfully the design performs.

Question 3Design and the design process

A designer produces a low-fidelity cardboard model to check how a handle feels in the hand. What is the main purpose of this model?

  1. To calculate production costs precisely
  2. To present final manufacturing details
  3. To test ergonomics quickly and cheaply Correct answer.
  4. To demonstrate the finished surface finish

Explanation

Low-fidelity models such as cardboard mock-ups allow fast, inexpensive testing of form, scale and ergonomics before committing to detailed development. They support early feedback rather than accurate cost or finish representation.

Question 4Design and the design process

Which design approach begins with the needs and frustrations of the end user and iterates through testing?

  1. Reverse engineering
  2. Design for manufacture
  3. Value analysis
  4. Human-centred design Correct answer.

Explanation

Human-centred design places the user's needs, abilities and context at the centre of each decision, using research and iterative testing. The other approaches focus on production efficiency, analysing existing products, or cost reduction.

Question 5Design and the design process

In a design brief, what is the primary role of the problem statement?

  1. To define the need the design must address Correct answer.
  2. To list the materials to be purchased
  3. To show the manufacturing schedule
  4. To record the final test results

Explanation

The problem statement clarifies the need or opportunity the designer is responding to, giving direction for later research and idea generation. Materials, schedules and test results are developed later in the process.

Question 6Design and the design process

A designer uses a mind map to explore related ideas around a new lamp concept. Which phase of the design process is this?

  1. Idea generation Correct answer.
  2. Production planning
  3. Market research
  4. Evaluation

Explanation

Mind mapping is a divergent thinking technique used during idea generation to branch out associations and possibilities. It is not an evaluation tool, a production plan or a market research method.

Question 7Design and the design process

Which document typically states the design's intended purpose, target user and key requirements before development begins?

  1. Design brief Correct answer.
  2. Quality control record
  3. Gantt chart
  4. Cutting list

Explanation

The design brief summarises the client or user need, the purpose of the product and the main requirements that will guide development. A Gantt chart schedules tasks, a cutting list specifies materials, and quality records document inspection.

Question 8Design and the design process

A designer repeatedly refines a design after each round of user testing. This best illustrates which characteristic of the design process?

  1. Iteration Correct answer.
  2. Standardisation
  3. Automation
  4. Outsourcing

Explanation

Iteration is the cyclical repetition of design, test and refine steps, with each loop improving the solution based on feedback. It is a defining feature of modern design processes rather than a production or business strategy.

Question 9Design and the design process

A designer is choosing between three concepts and scores each against weighted criteria. Which tool is being used?

  1. Decision matrix Correct answer.
  2. Orthographic projection
  3. Mood board
  4. Gantt chart

Explanation

A decision matrix lists concepts against weighted criteria and totals the scores to make the selection transparent and defensible. Mood boards communicate style, orthographic drawings specify geometry, and Gantt charts schedule tasks.

Question 10Design and the design process

A client insists a new chair must support a 120 kg user. In design terms, this requirement is best described as:

  1. A performance criterion
  2. An aesthetic consideration
  3. A marketing objective
  4. A design constraint Correct answer.

Explanation

A load requirement is a fixed boundary that the design must satisfy, making it a constraint. Criteria are qualities used to compare how well solutions perform, while aesthetics and marketing are separate concerns.

Question 11Design and the design process

During research, a designer interviews five users about difficulties with existing products. Which research type does this represent?

  1. Tertiary market analysis
  2. Secondary quantitative research
  3. Primary qualitative research Correct answer.
  4. Experimental research

Explanation

Interviews generate new, first-hand data about users' experiences and opinions, making them primary and qualitative. Secondary data already exists, quantitative data is numerical, and experimental research involves controlled testing.

Question 12Design and the design process

A designer builds a full-scale, functioning prototype from the intended production materials. What is the main advantage of this approach?

  1. It guarantees the design meets all criteria
  2. It reveals real performance and manufacturing issues Correct answer.
  3. It avoids the need for any user testing
  4. It is the fastest and cheapest form of modelling

Explanation

A high-fidelity prototype made from production materials exposes genuine performance, durability and manufacturing problems that simple mock-ups cannot. It is slower and costlier than low-fidelity work, and it still requires testing and evaluation.

Question 13Design and the design process

A designer notices the same usability problem appearing in several rounds of testing. What is the most appropriate next action?

  1. Reduce the number of test participants
  2. Revise the design to address the underlying cause Correct answer.
  3. Ignore it because the prototype is only a model
  4. Add more features to distract users

Explanation

Recurring problems across testing rounds indicate a systematic issue that should be diagnosed and designed out in the next iteration. Ignoring it, distracting users or reducing feedback all undermine the purpose of iterative testing.

Question 14Design and the design process

Which technique is most useful for a designer exploring how a product will be used in a real setting before building anything?

  1. Cost-benefit analysis
  2. Scenario building Correct answer.
  3. Tolerance analysis
  4. Bill of materials

Explanation

Scenario building describes realistic situations of use, helping the designer understand context, tasks and user needs early in the process. The other tools address materials, manufacturing precision and financial comparison.

Question 15Design and the design process

A designer sets a target that the product must be recyclable at end of life. This requirement is best classified as:

  1. A sustainability criterion Correct answer.
  2. An ergonomic requirement
  3. A legal obligation
  4. A functional constraint

Explanation

End-of-life recyclability is a sustainability-based criterion used to judge how well a design performs environmentally. It is not a functional constraint, an ergonomic requirement or necessarily a legal obligation.

Question 16Design and the design process

A designer produces several quick thumbnail sketches before developing one concept in detail. What is the main benefit of this stage?

  1. It proves the concept will be profitable
  2. It finalises dimensions for production
  3. It widens the range of possibilities explored Correct answer.
  4. It replaces the need for a design brief

Explanation

Rapid thumbnail sketching encourages divergent thinking and lets many ideas be compared before committing to detailed development. It does not finalise production dimensions, prove profitability or replace the brief.

Question 17Design and the design process

A designer conducts a SWOT analysis on a proposed product concept. Which pair of factors does this tool examine internally?

  1. Weaknesses and threats
  2. Opportunities and threats
  3. Strengths and opportunities
  4. Strengths and weaknesses Correct answer.

Explanation

SWOT separates internal factors, strengths and weaknesses, from external factors, opportunities and threats. The internal analysis focuses on what the concept or organisation controls.

Question 18Design and the design process

A designer's initial concept fails a load test, and the failure is traced to a joint design. Which response best reflects iterative design?

  1. Redesign the joint and retest the revised model Correct answer.
  2. Abandon the entire project immediately
  3. Increase the marketing budget
  4. Submit the failing design for production

Explanation

Iterative design treats failure as information, using the diagnosis to revise the specific weak element and then retest. Abandoning the project, changing marketing or proceeding to production ignores the evidence gathered.

Question 19Design and the design process

Which statement best explains why a designer should define evaluation criteria before developing solutions?

  1. It guarantees the cheapest design is chosen
  2. It removes the need to test any prototype
  3. It prevents new ideas from emerging
  4. It allows concepts to be judged consistently and objectively Correct answer.

Explanation

Establishing criteria early gives a consistent, transparent basis for comparing concepts and avoids bias toward a favoured idea. It does not eliminate testing, guarantee low cost or suppress creativity.

Question 20Design and the design process

A company asks a designer to reduce material use in an existing product without changing its function. Which approach is most appropriate?

  1. Reverse engineering
  2. Benchmarking
  3. Brainstorming
  4. Value analysis Correct answer.

Explanation

Value analysis systematically examines an existing product to reduce cost or material while preserving required function. Reverse engineering explains how a product works, brainstorming generates ideas, and benchmarking compares against competitors.

Question 21Design and the design process

Two concepts score equally in a decision matrix, but one relies on a supplier with an unreliable delivery record. Which refinement to the matrix is most defensible?

  1. Discard the matrix and choose randomly
  2. Add supply reliability as a weighted criterion Correct answer.
  3. Double the scores of the preferred concept
  4. Remove all criteria to simplify the decision

Explanation

When a decision hinges on a factor not yet captured, adding it as a weighted criterion makes the comparison complete and transparent. Random choice, removing criteria or arbitrarily doubling scores undermines the tool's purpose.

Question 22Design and the design process

A designer claims a new packaging concept is sustainable because it uses recycled card. Which additional consideration is most necessary before accepting the claim?

  1. The colour of the printed graphics
  2. The full life cycle including transport and disposal Correct answer.
  3. The number of design sketches produced
  4. The size of the marketing campaign

Explanation

Sustainability claims require a life-cycle perspective covering material sourcing, manufacture, transport, use and end-of-life disposal. A single material choice can be offset by impacts elsewhere in the cycle.

Question 23Design and the design process

A designer must satisfy a strict deadline and a limited budget while meeting user needs. What does this situation best illustrate?

  1. A failure of prototyping
  2. A lack of design criteria
  3. Competing constraints requiring trade-offs Correct answer.
  4. An absence of user research

Explanation

Time, cost and performance are competing constraints, and the designer must make reasoned trade-offs to balance them. The situation does not indicate missing criteria, absent research or failed prototyping.

Question 24Design and the design process

A designer uses a focus group of eight users and then generalises the findings to the whole population. What is the main limitation of this approach?

  1. Focus groups are always more expensive than surveys
  2. Users in focus groups never express opinions
  3. The small sample may not represent the wider population Correct answer.
  4. Focus groups cannot generate qualitative data

Explanation

A small focus group provides rich qualitative insight but limited statistical representativeness, so broad generalisations are risky. Focus groups do generate qualitative data and can be cost-effective, so the sample size is the key limitation.

Question 25Design and the design process

A designer argues that because a prototype passed testing once, the design is proven. Which criticism of this reasoning is most valid?

  1. Prototypes should never be tested
  2. Testing always produces false results
  3. A single test may not reveal variability in use and conditions Correct answer.
  4. Passing one test proves profitability

Explanation

One successful test does not account for variation in users, environments, materials or repeated use, so conclusions should be cautious. Repeated and varied testing builds confidence in a design's reliability.

Question 26Design and the design process

In the design process, what is the primary purpose of developing a design brief?

  1. To record the final dimensions of the completed product
  2. To list the names of every supplier used in production
  3. To establish the problem, constraints and intended outcomes before design work begins Correct answer.
  4. To calculate the retail price of the finished item

Explanation

A design brief frames the problem by identifying the client or user, the need being addressed, key constraints and the intended outcome. It is created early and guides all later decisions, so it must precede concept development rather than describe finished work.

Question 27Design and the design process

A designer lists every step a user performs when making coffee with a new machine, from filling the tank to cleaning it. Which design tool is being applied?

  1. A tolerance analysis
  2. A user journey map Correct answer.
  3. A decision matrix
  4. A morphological chart

Explanation

A user journey map sequences the stages a person goes through when interacting with a product, capturing actions and pain points over time. It helps designers see where friction occurs across the whole experience rather than at a single moment.

Question 28Design and the design process

A designer needs to generate a wide range of possible solutions to a sub-problem quickly before judging any of them. Which approach best supports this goal?

  1. Waiting until the client approves a single direction
  2. Producing many varied sketches without judging them yet Correct answer.
  3. Selecting the first workable idea and refining it fully
  4. Evaluating each idea against the brief as soon as it appears

Explanation

Divergent thinking deliberately separates idea generation from evaluation so that quantity and variety are not suppressed by early criticism. Deferring judgement allows unusual combinations to emerge that can later be screened. Premature evaluation narrows the search space too soon.

Question 29Design and the design process

A designer records the percentage of users who could open a new jar lid without assistance. Which type of data has been collected?

  1. Nominal data
  2. Quantitative data Correct answer.
  3. Anecdotal data
  4. Qualitative data

Explanation

Quantitative data is numerical and can be counted or measured, such as a percentage of successful users. It allows comparison between prototypes and statistical summary. Qualitative data instead captures descriptive, non-numerical impressions.

Question 30Design and the design process

A designer specifies that a new kettle handle must remain below 40 degrees Celsius during use. Which type of design requirement does this represent?

  1. A performance requirement Correct answer.
  2. An aesthetic requirement
  3. A packaging requirement
  4. A marketing requirement

Explanation

A measurable limit on how a product behaves in use, such as a maximum surface temperature, is a performance requirement. It can be tested objectively against a stated value. Aesthetic requirements concern appearance rather than functional behaviour.

Question 31Design and the design process

A designer builds a small-scale model from foam to check the overall proportions of a furniture piece. Which purpose does this model serve?

  1. Testing structural strength under load
  2. Verifying manufacturing tolerances
  3. Confirming the visual form and scale Correct answer.
  4. Assessing electrical safety

Explanation

A low-fidelity foam model allows quick exploration of form, proportion and scale without the cost of functional materials. It communicates shape rather than proving engineering performance. Strength and tolerance testing require different materials and methods.

Question 32Design and the design process

A designer arranges tasks on a timeline showing research, concept development, prototyping and evaluation with overlapping periods. Which planning tool is being used?

  1. A flow chart
  2. A bill of materials
  3. A Gantt chart Correct answer.
  4. A parts list

Explanation

A Gantt chart displays project tasks as bars along a time axis, making durations, overlaps and dependencies visible. This supports scheduling and monitoring of progress across a design project. The other tools describe components or logic, not time.

Question 33Design and the design process

A designer asks users to think aloud while attempting to assemble a flat-pack shelf for the first time. Which evaluation method is being used?

  1. A focus group discussion
  2. A usability observation Correct answer.
  3. A market survey
  4. A controlled laboratory stress test

Explanation

Usability observation involves watching representative users attempt real tasks and noting where they struggle, often with think-aloud commentary. It reveals practical difficulties in context rather than opinions gathered in discussion. Stress testing instead measures physical performance.

Question 34Design and the design process

A designer compares a proposed material against alternatives using criteria such as cost, durability and recyclability. Which stage of the design process does this most directly support?

  1. Defining the initial problem
  2. Writing the user manual
  3. Selecting and justifying materials Correct answer.
  4. Packaging the finished product

Explanation

Comparing materials against explicit criteria is the process of justifying material selection, which links performance needs to available options. The comparison produces evidence for why one material is chosen over another. It occurs during development rather than at problem definition.

Question 35Design and the design process

A designer uses a physical prototype to test how a product feels in the hand during repeated use. Which evaluation focus does this represent?

  1. Financial evaluation
  2. Environmental evaluation
  3. Ergonomic evaluation Correct answer.
  4. Legal evaluation

Explanation

Ergonomic evaluation examines how well a product fits the human body, including comfort, grip and effort during repeated use. Physical prototypes allow these human-factor issues to be experienced and measured. Financial, environmental and legal reviews use different evidence.

Question 36Design and the design process

A designer uses a computer model to simulate how heat spreads through a new enclosure before any physical part is made. What is the main advantage of this approach?

  1. It eliminates uncertainty from material properties
  2. It guarantees the final product will pass certification
  3. It removes the need for any physical testing
  4. It allows many design variations to be tested cheaply and quickly Correct answer.

Explanation

Simulation lets designers vary geometry and parameters and observe predicted behaviour without building each version, saving time and cost. It informs decisions before committing to manufacture. However, results still depend on assumptions and must be validated physically.

Question 37Design and the design process

A designer reviews a concept and finds it meets user needs but would require a production method the factory cannot perform. Which conclusion is most appropriate?

  1. The concept is fully feasible and can proceed unchanged
  2. The concept is desirable but not currently feasible Correct answer.
  3. The concept is feasible but not desirable
  4. The concept fails on both desirability and feasibility

Explanation

Desirability concerns whether people want and need the product, while feasibility concerns whether it can actually be made with available capability. A concept that meets user needs but cannot be manufactured sits between these tests. It may be redesigned or reconsidered rather than approved.

Question 38Design and the design process

A designer keeps a log of every change made to a concept, including the reason and date. What is the main value of this record?

  1. It guarantees the concept will meet the brief
  2. It replaces the need for testing the concept
  3. It reduces the number of prototypes required
  4. It provides traceability of decisions for later review and accountability Correct answer.

Explanation

A change log creates traceability, showing what was altered, why and when, which supports review, teamwork and accountability. It documents the reasoning behind the evolving design. It does not substitute for testing or guarantee outcomes.

Question 39Design and the design process

A designer gathers feedback from a small group of users who all share similar backgrounds and habits. Which limitation most affects the reliability of the conclusions?

  1. The users were asked too many open questions
  2. The feedback was collected too quickly to be useful
  3. The feedback was recorded in written form
  4. The sample lacks diversity and may not represent other users Correct answer.

Explanation

When a sample shares similar backgrounds, the findings reflect that narrow group and may not transfer to the wider population. Representativeness depends on variety in the sample, not merely its size. Conclusions therefore need to be qualified.

Question 40Design and the design process

A designer plans to release a product and needs to confirm it complies with relevant safety standards before sale. Which action best supports this requirement?

  1. Having the product tested against the published standard by a competent body Correct answer.
  2. Relying on the designer's own confidence in the concept
  3. Comparing the product with a competitor's marketing claims
  4. Asking a small group of friends to try the product

Explanation

Compliance is demonstrated by testing against the published standard, usually by a competent or accredited body, which produces evidence accepted by regulators and buyers. Personal confidence or informal trials do not provide verifiable proof. The results are documented for accountability.

Question 41Design and technology in society and the environment

Which term describes meeting present needs without compromising the ability of future generations to meet their own needs?

  1. Industrialisation
  2. Globalisation
  3. Obsolescence
  4. Sustainable development Correct answer.

Explanation

Sustainable development balances economic, social and environmental considerations so that resources are used responsibly. It requires designers to consider whole-of-life impacts such as material sourcing, energy use and end-of-life disposal.

Question 42Design and technology in society and the environment

A designer specifies recycled aluminium for a new laptop case. Which life-cycle stage is most directly improved by this choice?

  1. Consumer instruction
  2. Product distribution
  3. Retail display
  4. Material extraction and processing Correct answer.

Explanation

Recycled aluminium reduces the need to mine and refine bauxite, so the largest benefit occurs at the material acquisition stage of the life cycle. This stage typically accounts for a substantial share of a product's embodied energy and emissions.

Question 43Design and technology in society and the environment

What does the term 'carbon footprint' measure?

  1. The mass of solid waste sent to landfill
  2. The amount of electricity used by a household
  3. The volume of water consumed in manufacturing
  4. Total greenhouse gas emissions associated with a product or activity Correct answer.

Explanation

A carbon footprint expresses the greenhouse gases released across a product's life, usually converted to carbon dioxide equivalent. It allows designers and consumers to compare the climate impact of different choices.

Question 44Design and technology in society and the environment

Which practice best demonstrates design for disassembly?

  1. Applying a permanent epoxy coating to all surfaces
  2. Sealing the casing with tamper-proof rivets
  3. Using snap-fit joints instead of glued seams Correct answer.
  4. Bonding dissimilar plastics into one moulded shell

Explanation

Design for disassembly uses reversible fastenings so components can be separated for repair, reuse or recycling. Snap-fits allow parts to be taken apart without destroying the materials.

Question 45Design and technology in society and the environment

Which legislation-style principle makes producers responsible for the end-of-life management of the products they place on the market?

  1. Extended producer responsibility Correct answer.
  2. Planned obsolescence
  3. Just-in-time production
  4. Mass customisation

Explanation

Extended producer responsibility shifts the cost and duty of take-back and recycling onto manufacturers. It encourages designers to reduce waste and design products that are easier to recover.

Question 46Design and technology in society and the environment

A community group opposes a new factory because of likely noise and traffic. Which design response best reflects social responsibility?

  1. Proceeding with the original plan to avoid delays
  2. Consulting residents and adjusting operating hours and transport routes Correct answer.
  3. Relocating the factory without informing the community
  4. Increasing output to offset the cost of complaints

Explanation

Social responsibility requires designers and manufacturers to consider the impact of their decisions on affected communities. Consultation and mitigation of noise and traffic address legitimate stakeholder concerns.

Question 47Design and technology in society and the environment

Which energy source is classified as renewable?

  1. Natural gas
  2. Diesel
  3. Brown coal
  4. Wind Correct answer.

Explanation

Renewable sources are replenished naturally at a rate comparable to their use, and wind is continually generated by atmospheric processes. Fossil fuels such as gas, coal and diesel are finite and release stored carbon when burned.

Question 48Design and technology in society and the environment

A manufacturer claims a product is 'eco-friendly' but provides no supporting data. What is the most appropriate professional response from a designer?

  1. Request verifiable evidence before allowing the claim to be used Correct answer.
  2. Accept the claim because it sounds positive
  3. Add further vague environmental wording to strengthen the message
  4. Remove all environmental information from the packaging

Explanation

Environmental claims should be substantiated with evidence so consumers are not misled, which is the basis of greenwashing concerns. Designers have an ethical duty to ensure marketing statements are accurate and verifiable.

Question 49Design and technology in society and the environment

A phone maker designs batteries that cannot be replaced by the user, shortening the practical life of the device. Which concept does this illustrate?

  1. Cradle-to-cradle design
  2. Design for repair
  3. Circular economy
  4. Planned obsolescence Correct answer.

Explanation

Planned obsolescence shortens a product's useful life so consumers replace it sooner. Sealed, non-replaceable batteries force replacement when the battery degrades even if the rest of the device still works.

Question 50Design and technology in society and the environment

Which scenario best illustrates the rebound effect of an energy-efficient appliance?

  1. A cheaper-to-run heater is used more often, so total energy use rises Correct answer.
  2. A manufacturer sells fewer heaters because they last longer
  3. A heater uses less energy and total household energy falls
  4. A household switches to a more expensive energy supplier

Explanation

The rebound effect occurs when efficiency gains are partly or wholly offset by increased use of the product or service. Lower running costs can encourage more frequent or longer use, eroding the expected savings.
