Question 1Design process and the iterative design cycle

In the iterative design cycle, what is the main purpose of the evaluation stage?

  1. To compare the prototype against the design specification and identify improvements Correct answer.
  2. To generate the initial design brief for the client
  3. To calculate the retail price of the finished product
  4. To manufacture the final product in the chosen material

Explanation

Evaluation judges how well a design meets the specification and user needs, and it feeds findings back into the next iteration of the cycle. It is a reflective stage rather than a making or costing stage, so its output is a set of decisions about what to change.

Question 2Design process and the iterative design cycle

A designer writes a short statement of the problem, the target user and the key constraints before sketching ideas. Which part of the design process does this describe?

  1. Writing the design brief and specification Correct answer.
  2. Producing a working drawing for manufacture
  3. Testing a completed prototype
  4. Carrying out a final product evaluation

Explanation

The brief states the problem and user in broad terms, while the specification turns this into measurable requirements and constraints. Both are produced before concept generation so that later ideas can be judged against them.

Question 3Design process and the iterative design cycle

Which activity is the clearest example of divergent thinking during the design process?

  1. Selecting the single best concept using a scoring matrix
  2. Measuring a prototype to check tolerances
  3. Generating many different initial concepts without judging them yet Correct answer.
  4. Writing the final evaluation against the specification

Explanation

Divergent thinking widens the range of possibilities, so it is associated with generating numerous varied ideas before criticism. Convergent thinking then narrows the field by judging and selecting.

Question 4Design process and the iterative design cycle

Why is the design cycle described as iterative rather than linear?

  1. Because the process always starts with manufacture and ends with research
  2. Because stages are revisited and earlier decisions are revised as new evidence appears Correct answer.
  3. Because only professional designers are allowed to repeat stages
  4. Because each stage must be completed exactly once before the next begins

Explanation

Iteration means looping back: testing or evaluation can reveal that the specification, concept or materials must be reconsidered. A linear model would treat each stage as a single fixed step, which does not reflect real design practice.

Question 5Design process and the iterative design cycle

During research, a student interviews five intended users about how they carry shopping. Which type of data is being collected?

  1. Secondary quantitative data
  2. Primary quantitative data
  3. Primary qualitative data Correct answer.
  4. Secondary qualitative data

Explanation

Data gathered first-hand by the designer is primary, and interview responses describing experiences and opinions are qualitative. Secondary data would already exist in published sources, and quantitative data would be numerical.

Question 6Design process and the iterative design cycle

What is the main function of a design specification?

  1. To replace the need for any prototype testing
  2. To record the final selling price of the product
  3. To list measurable requirements the product must meet Correct answer.
  4. To advertise the finished product to customers

Explanation

A specification translates the brief into criteria such as size, cost, safety and performance that can be tested. It gives designers and evaluators an objective standard against which concepts and prototypes are judged.

Question 7Design process and the iterative design cycle

A designer builds a low-cost model from card to check how a handle feels in the hand. What is this model called?

  1. A virtual simulation used for stress analysis
  2. A design brief used for client approval
  3. A final production tool used for moulding
  4. A physical prototype used for ergonomic testing Correct answer.

Explanation

A card model is a physical prototype that allows the designer to test form and ergonomics cheaply before committing to production materials. It is a modelling tool for learning, not a finished product or a brief.

Question 8Design process and the iterative design cycle

Which action best shows that a designer has considered sustainability during the design cycle?

  1. Ignoring the product's energy use because it is small
  2. Adding extra packaging to make the product look more expensive
  3. Choosing a material that can be recycled and planning how parts can be disassembled Correct answer.
  4. Increasing the number of different materials used in one product

Explanation

Sustainable design considers material choice, end-of-life recovery and energy use across the product life cycle. Designing for disassembly and recycling reduces waste and keeps materials in use.

Question 9Design process and the iterative design cycle

A design team uses a weighted scoring matrix to compare three concepts against criteria such as cost, safety and ease of manufacture. What is the main purpose of this tool?

  1. To test the strength of a physical prototype
  2. To calculate the exact manufacturing cost of each concept
  3. To generate additional concepts that were missed
  4. To make concept selection more objective and transparent Correct answer.

Explanation

A weighted matrix scores concepts against agreed criteria, so decisions can be justified and compared rather than made on personal preference. It supports convergent thinking by narrowing options.

Question 10Design process and the iterative design cycle

After testing, a prototype's lid leaks. The designer changes the seal material and retests. Which feature of the design cycle does this best illustrate?

  1. Final evaluation of a finished product
  2. Linear one-pass design
  3. Market research into competitor products
  4. Iteration driven by test evidence Correct answer.

Explanation

Testing revealed a fault, the design was modified, and the change was verified by retesting, which is the essence of iteration. The loop from test back to development is what distinguishes iterative from linear design.

Question 11Design process and the iterative design cycle

A designer collects data on hand grip strength to decide the force needed to open a jar lid. Which research approach is most appropriate?

  1. A focus group about packaging colours
  2. Anthropometric measurement of a sample of intended users Correct answer.
  3. A review of historical sales figures
  4. An interview about brand loyalty

Explanation

Anthropometric data describes human body dimensions and capabilities such as grip strength, which directly informs the force a lid should require. Colour, sales and brand data do not measure physical capability.

Question 12Design process and the iterative design cycle

A designer produces an isometric sketch of a concept before making a card model. Why is sketching used at this stage?

  1. To communicate and develop ideas quickly and cheaply Correct answer.
  2. To provide a legally binding manufacturing contract
  3. To measure the exact strength of the final material
  4. To replace the need for a design specification

Explanation

Sketches are fast and inexpensive, allowing many ideas to be explored and shared before committing to materials or manufacture. They support communication and development rather than replacing formal documents or testing.

Question 13Design process and the iterative design cycle

Which pair correctly matches a stage of the design cycle with its typical output?

  1. Research stage - a set of user needs and constraints Correct answer.
  2. Ideation stage - the final quality control report
  3. Manufacture stage - the design brief
  4. Evaluation stage - the first concept sketches

Explanation

Research produces information about users, contexts and constraints that informs later decisions. Each stage has characteristic outputs, and matching them correctly shows understanding of how the cycle is structured.

Question 14Design process and the iterative design cycle

A client asks for a storage box for a small flat. The designer sets a maximum footprint of 400 mm by 300 mm. Which part of the design process does this belong to?

  1. Turning the brief into a measurable specification Correct answer.
  2. Manufacturing the final product
  3. Evaluating the finished product
  4. Marketing the product to retailers

Explanation

A numeric limit on size is a measurable criterion, so it belongs in the specification derived from the brief. The brief states the need broadly; the specification makes it testable.

Question 15Design process and the iterative design cycle

A designer uses computer-aided design to simulate how a bracket bends under load before making it. What is the main advantage of this approach?

  1. Weak points can be found and corrected before physical materials are used Correct answer.
  2. It automatically writes the design specification
  3. It guarantees the product will pass all safety regulations
  4. It removes the need for any physical prototype at all

Explanation

Simulation allows stress and performance to be explored cheaply and quickly, so problems are found early when changes are least costly. It informs physical prototyping rather than replacing verification or specification writing.

Question 16Design process and the iterative design cycle

During evaluation, a designer compares a prototype's mass with the specification target of 500 g and finds it is 620 g. What is the most appropriate next step in the iterative cycle?

  1. Abandon the specification and set a new target of 620 g
  2. Return to development to reduce mass, then retest Correct answer.
  3. Accept the prototype because it works
  4. Proceed straight to full-scale manufacture

Explanation

When a measured value fails a specification target, the iterative response is to revisit the design and retest after changes. Accepting the failure or rewriting the target undermines the purpose of having a specification.

Question 17Design process and the iterative design cycle

A designer asks users to rate a prototype's comfort on a five-point scale after use. Which research method is being used?

  1. A controlled laboratory stress test
  2. A patent search
  3. A user trial with a rating questionnaire Correct answer.
  4. A material data sheet review

Explanation

Giving users a prototype to use and then collecting ratings is a user trial that gathers feedback on experience. It produces qualitative or ordinal data about comfort rather than technical measurements.

Question 18Design process and the iterative design cycle

A team builds three different concepts and tests each with users before choosing one to develop. Which benefit does this approach give?

  1. It guarantees the cheapest concept will be chosen
  2. It shortens the process by skipping evaluation
  3. It removes the need to write a specification
  4. Decisions are based on evidence from real use rather than opinion alone Correct answer.

Explanation

Testing several concepts with users produces comparative evidence, making selection more reliable than guesswork. The approach adds evaluation into the cycle rather than removing it, and cost is only one criterion.

Question 19Design process and the iterative design cycle

Which statement best explains why designers produce a specification before generating detailed solutions?

  1. It gives objective criteria against which concepts can later be judged Correct answer.
  2. It replaces the need for user research
  3. It proves the product will be profitable
  4. It fixes the final appearance of the product in advance

Explanation

A specification defines measurable requirements, so later concepts can be evaluated consistently and fairly. It constrains the solution space without dictating a single appearance, and it depends on research rather than replacing it.

Question 20Design process and the iterative design cycle

A designer keeps a record of every change made to a design, with the reason for each change. Why is this record valuable in the iterative cycle?

  1. It guarantees the design will meet all user needs
  2. It replaces the design specification
  3. It removes the need to test subsequent prototypes
  4. It allows decisions to be reviewed and justified if problems emerge later Correct answer.

Explanation

Documenting changes and their reasons creates a traceable design history, so decisions can be revisited and defended. It supports review and learning but does not substitute for testing or the specification.

Question 21Design process and the iterative design cycle

A designer wants to choose between two concepts with conflicting strengths: one is cheaper, the other is more durable. Which approach best supports a reasoned decision?

  1. Choose the concept the designer personally prefers
  2. Delay the decision indefinitely to avoid risk
  3. Choose the cheaper concept without further analysis
  4. Score both against weighted criteria agreed from the specification Correct answer.

Explanation

When criteria conflict, weighting them according to the specification makes the trade-off explicit and the decision defensible. Personal preference or a single factor such as cost ignores other requirements.

Question 22Design process and the iterative design cycle

A company redesigns a kettle. User trials show the handle gets hot, so the team changes the handle material and retests. Later, a cost review shows the new material is too expensive, so a third material is trialled. Which description best fits this sequence?

  1. Nested iteration, where evaluation findings repeatedly redirect development Correct answer.
  2. A process in which the specification was never used
  3. A single evaluation carried out only at the end
  4. A strictly linear process with no feedback

Explanation

Each evaluation revealed a new constraint that sent the team back to development, producing repeated loops within the cycle. This shows how technical and commercial findings both drive iteration rather than a single end-point check.

Question 23Design process and the iterative design cycle

A designer must decide whether to test a prototype with ten users or with one hundred. Which consideration is most relevant to this decision?

  1. The colour scheme chosen for the prototype
  2. The retail price planned for the final product
  3. The balance between confidence in the findings and the time and cost of testing Correct answer.
  4. The number of sketches produced during ideation

Explanation

Larger samples generally increase confidence in findings but require more time, money and coordination, so the designer must balance reliability against resources. The other factors do not affect the statistical value of user testing.

Question 24Design process and the iterative design cycle

A designer claims a new backpack is fully sustainable because it uses recycled fabric. Which criticism of this claim is most valid within the design cycle?

  1. The claim is valid because one sustainable feature is sufficient
  2. Recycled fabric can never be used in a successful product
  3. Other life-cycle impacts such as manufacture, transport and disposal must also be assessed Correct answer.
  4. Sustainability cannot be considered at the design stage

Explanation

Sustainability is judged across the whole life cycle, so material choice alone does not establish an overall claim. Manufacture, transport, durability and end-of-life all contribute to environmental impact and must be evaluated.

Question 25Design process and the iterative design cycle

A prototype meets its specification in tests, but user trials show people find it confusing to operate. What does this reveal about the design process?

  1. The evaluation stage should be removed
  2. User trials are unnecessary when tests pass
  3. The prototype should be manufactured without change
  4. The specification may have omitted an important usability requirement Correct answer.

Explanation

Passing technical tests does not guarantee usability, which suggests the specification failed to capture a key user need. The iterative response is to revise the specification and design, then retest.

Question 26Design process and the iterative design cycle

A designer is starting a new project to design a reusable water bottle for schoolchildren. Which action correctly begins the iterative design cycle?

  1. Write the marketing plan for the finished bottle
  2. Identify the needs of the users and research the problem Correct answer.
  3. Select the final manufacturing material for the bottle
  4. Produce a working prototype of the bottle

Explanation

The design cycle opens with identifying and researching the problem, since user needs and constraints shape every later decision. Material selection, prototyping and marketing all depend on this initial understanding and come later.

Question 27Design process and the iterative design cycle

In the iterative design cycle, what does the word 'iterative' most accurately describe?

  1. Producing a single final solution without changes
  2. Repeating stages in loops so earlier work is revisited and improved Correct answer.
  3. Working only with computer software
  4. Completing each stage once in a fixed order

Explanation

Iteration means cycling back through stages, such as returning from evaluation to research or idea generation, to refine the design. It is the repeated improvement loop, not a single pass through fixed steps.

Question 28Design process and the iterative design cycle

A designer writes down the problem as 'Design a bag for students'. Which revision makes this problem statement more useful for the design cycle?

  1. Design something students will like
  2. Design a product for people
  3. Design a waterproof backpack that carries a 15-inch laptop and weighs under 1 kg Correct answer.
  4. Design a bag

Explanation

A useful problem statement names the product, key user needs and measurable constraints, giving criteria the designer can test against. The other options are too vague to guide decisions or evaluation.

Question 29Design process and the iterative design cycle

A designer creates a quick freehand drawing to capture a first idea during the concept stage. Which type of drawing is this?

  1. Exploded view
  2. Working drawing
  3. Orthographic projection
  4. Concept sketch Correct answer.

Explanation

A fast freehand drawing that records an early idea is a concept sketch, used to explore and communicate thinking quickly. Working drawings, orthographic views and exploded views are precise or technical outputs produced later.

Question 30Design process and the iterative design cycle

A designer gathers feedback from users after they try a prototype, then uses it to change the design and test again. Which part of the iterative cycle does this best illustrate?

  1. Final manufacture
  2. Evaluation feeding back into redesign Correct answer.
  3. Initial problem identification
  4. Specification writing

Explanation

Collecting user feedback and acting on it is evaluation, and using that evaluation to change and retest shows the feedback loop of iteration. Problem identification and specification writing occur earlier, while manufacture follows a settled design.

Question 31Design process and the iterative design cycle

A designer lists 'the device must survive a 1 m drop onto concrete without cracking' as a requirement. In which part of the design process does this belong?

  1. The assembly drawing
  2. The design specification Correct answer.
  3. The concept sketch
  4. The evaluation report

Explanation

A measurable performance requirement belongs in the design specification, which sets the criteria the design must meet. Sketches explore ideas, evaluation reports judge results, and assembly drawings show how parts fit together.

Question 32Design process and the iterative design cycle

During idea generation a team deliberately produces many rough ideas, including some that seem impractical, before narrowing them down. Why is this approach useful in the design cycle?

  1. It removes the need for any evaluation later
  2. It widens the range of possible solutions before selection Correct answer.
  3. It shortens the process by avoiding research
  4. It guarantees the first idea will be the best

Explanation

Generating many ideas, including unusual ones, widens the solution space so that stronger concepts can be selected and developed. It does not guarantee a best first idea, remove evaluation, or replace research.

Question 33Design process and the iterative design cycle

A designer uses a mood board of colours, textures and images at the start of a project. What is its main purpose in the design cycle?

  1. To calculate the manufacturing cost of a product
  2. To record the final dimensions of a component
  3. To define the visual direction and intended feel of a design Correct answer.
  4. To test the strength of a material

Explanation

A mood board gathers visual references to establish the style, colour palette and feel that will guide design decisions. It is a source of inspiration and direction, not a cost, strength or dimension record.

Question 34Design process and the iterative design cycle

A designer builds a prototype, tests it, finds a weakness, modifies the design and builds a second prototype. What is the main reason for making a second prototype rather than only adjusting the drawing?

  1. To make the project take longer
  2. To reduce the amount of research needed
  3. To confirm the modification actually solves the problem in practice Correct answer.
  4. To avoid having to evaluate the design again

Explanation

A physical prototype lets the designer verify that the change works under real conditions, which a drawing alone cannot confirm. Evaluation is still required, research needs are unchanged, and extra time is not a benefit.

Question 35Design process and the iterative design cycle

A designer is deciding which of four concepts to develop. Which approach best supports a fair, evidence-based decision in the design cycle?

  1. Choose the concept the designer personally likes most
  2. Score each concept against the specification criteria and compare the totals Correct answer.
  3. Choose the concept that was drawn first
  4. Choose the concept that is cheapest to make regardless of other factors

Explanation

Scoring concepts against agreed specification criteria makes the decision transparent and based on evidence rather than preference. Personal liking, cost alone or the order of drawing ignore the wider requirements.

Question 36Design process and the iterative design cycle

A designer makes a prototype, gives it to five users to try for a week, and observes and interviews them. Which stage of the design cycle is being carried out?

  1. Concept sketching
  2. User testing and evaluation Correct answer.
  3. Materials research
  4. Specification writing

Explanation

Giving a prototype to users and gathering observations and interviews is user testing that feeds evaluation. Specification writing and sketching precede the prototype, and materials research concerns material properties rather than user experience.

Question 37Design process and the iterative design cycle

A designer needs to understand how a group of elderly users currently opens medicine packaging. Which research method best suits this aim?

  1. Measuring the packaging with digital callipers
  2. Observing and interviewing a sample of elderly users as they open packaging Correct answer.
  3. A postal questionnaire sent to the general public
  4. Reading the manufacturer's sales figures

Explanation

Direct observation and interviews with the target users reveal the real difficulties and behaviours involved, which is the aim of the research. General questionnaires, sales figures and measurements do not show how elderly users struggle with opening.

Question 38Design process and the iterative design cycle

A designer is asked to reduce the environmental impact of a product. At which point in the design cycle can this aim be influenced most effectively?

  1. Only after the product has been sold
  2. Throughout, from material choice and specification to disposal Correct answer.
  3. Only during the marketing campaign
  4. Only at the final packaging stage

Explanation

Environmental impact is shaped by decisions made across the whole cycle, including material selection, manufacture, use and end-of-life disposal. Limiting the aim to packaging, after-sales or marketing misses the major impacts.

Question 39Design process and the iterative design cycle

A designer tests a prototype against the specification and it passes every criterion, but users say it is awkward to use. What is the most appropriate conclusion?

  1. The testing stage should be skipped next time
  2. The prototype should be manufactured immediately
  3. The users must be mistaken because the specification was met
  4. The specification criteria are incomplete and should be revised to include usability Correct answer.

Explanation

If a product meets the written criteria but users find it awkward, the criteria failed to capture an important requirement, so the specification should be revised and the design re-evaluated. Dismissing users, rushing to manufacture or skipping testing would embed the flaw.

Question 40Design process and the iterative design cycle

A design team claims its new chair is fully sustainable because the frame is made from recycled aluminium. Which criticism of this claim is most valid?

  1. The chair has not been tested by users
  2. The claim ignores other impacts such as energy use, upholstery materials and disposal Correct answer.
  3. Recycled aluminium is never strong enough for chairs
  4. Sustainability cannot be assessed for furniture

Explanation

A sustainability claim must consider the whole life cycle, including manufacturing energy, other materials and end-of-life disposal, not just one component. Recycled aluminium can be strong, furniture sustainability can be assessed, and user testing is a separate issue from environmental impact.

Question 41Materials, components and their properties

Which property describes a material's ability to be drawn out into a long thin wire without breaking?

  1. Elasticity
  2. Brittleness
  3. Ductility Correct answer.
  4. Malleability

Explanation

Ductility is the property that allows a metal to be permanently stretched into wire form, as seen when copper is drawn into cable. Malleability concerns flattening into sheet, brittleness concerns fracture, and elasticity concerns recovery of shape.

Question 42Materials, components and their properties

A designer needs a material for a school workshop hammer handle that resists repeated impact without shattering. Which property is most important?

  1. Transparency
  2. Toughness Correct answer.
  3. Thermal conductivity
  4. Hardness

Explanation

Toughness is the ability to absorb impact energy without cracking, which is exactly what an impact tool handle needs. Hardness resists surface scratching but a very hard material may be brittle, and conductivity and transparency are unrelated to impact resistance.

Question 43Materials, components and their properties

Which material is a thermoplastic that softens when reheated and can therefore be reshaped repeatedly?

  1. Melamine formaldehyde
  2. Acrylic (PMMA) Correct answer.
  3. Epoxy resin
  4. Urea formaldehyde

Explanation

Thermoplastics such as acrylic have long chain molecules held by weak intermolecular forces, so they soften on heating and can be remoulded many times. The other three are thermosetting polymers that cross-link permanently and char rather than soften.

Question 44Materials, components and their properties

Which characteristic distinguishes a ferrous metal from a non-ferrous metal?

  1. It cannot be recycled
  2. It is always more expensive per kilogram
  3. It contains iron and is usually magnetic Correct answer.
  4. It contains no carbon at all

Explanation

Ferrous metals are those based on iron, which makes them magnetic and liable to rust. Non-ferrous metals such as aluminium and copper contain no iron, but both groups can contain carbon or be recycled.

Question 45Materials, components and their properties

Which type of timber is produced by gluing thin veneers together with the grain of each layer rotated, giving more uniform strength?

  1. Medium density fibreboard
  2. Chipboard
  3. Plywood Correct answer.
  4. Solid hardwood

Explanation

Plywood is a manufactured board made from veneers stacked with alternating grain direction, which balances strength across the sheet. Chipboard and MDF are made from particles and fibres rather than veneers, and solid hardwood is a natural material with directional grain.

Question 46Materials, components and their properties

Which property of a ceramic such as alumina makes it suitable for a kitchen knife blade that keeps a sharp edge?

  1. High electrical conductivity
  2. Low melting point
  3. High ductility
  4. High hardness Correct answer.

Explanation

Hardness is resistance to scratching and wear, so a hard ceramic retains a sharp edge for longer than softer materials. Ceramics are brittle rather than ductile, melt at high temperature, and are generally electrical insulators.

Question 47Materials, components and their properties

Which property is being tested when a material specimen is clamped and struck repeatedly by a pendulum until it fractures?

  1. Water absorption
  2. Creep resistance
  3. Electrical resistance
  4. Impact resistance Correct answer.

Explanation

A pendulum impact test measures the energy absorbed before fracture, which is a measure of impact resistance or toughness. Creep concerns slow deformation under sustained load, while electrical resistance and water absorption are measured by entirely different tests.

Question 48Materials, components and their properties

Which material is a composite because it combines two distinct constituents to give improved properties?

  1. Brass
  2. Stainless steel
  3. Bronze
  4. Glass-reinforced plastic Correct answer.

Explanation

Glass-reinforced plastic combines glass fibres within a polymer matrix, so it is a composite of two distinct materials. Brass, bronze and stainless steel are alloys, which are metallic mixtures on a much finer scale rather than fibre-and-matrix composites.

Question 49Materials, components and their properties

A product needs a window that is transparent, easily shaped by heating and resistant to shattering into sharp splinters. Which material best meets these needs?

  1. Slate
  2. Cast iron
  3. Polycarbonate Correct answer.
  4. Aluminium

Explanation

Polycarbonate is a transparent thermoplastic with very high impact resistance, so it can be thermoformed and will not break into dangerous shards. The metals and slate listed are opaque and unsuitable for a window.

Question 50Materials, components and their properties

Why is a thermosetting plastic such as melamine formaldehyde chosen for a cafeteria tray rather than a thermoplastic?

  1. It keeps its rigid shape and resists heat once cured Correct answer.
  2. It can be remelted and reshaped after every use
  3. It has a lower density than any thermoplastic
  4. It conducts electricity better than thermoplastics

Explanation

Thermosets form permanent cross-links during curing, giving rigid, heat-resistant products that will not soften in a dishwasher. Thermoplastics soften on reheating, which is a disadvantage for a hot tray, and density or conductivity are not the deciding factors.
