Question 1Technological Practice

In technological practice, what is the primary purpose of developing a brief before any design work begins?

  1. To record the final specifications of the finished product
  2. To list the tools that will be used during construction
  3. To define the need, stakeholders, and constraints that will guide the outcome Correct answer.
  4. To calculate the manufacturing cost of the chosen solution

Explanation

A brief establishes the problem space: who the outcome is for, what need it addresses, and the constraints and specifications that will frame later decisions. It is a starting reference, not a record of the finished product or a construction checklist.

Question 2Technological Practice

A student interviews three users of a public recycling bin and observes how people actually dispose of waste. Which technological practice element does this best represent?

  1. Intellectual property checking
  2. Prototype testing and trialling
  3. Stakeholder consultation and needs analysis Correct answer.
  4. Conceptual design sketching

Explanation

Gathering information from users through interviews and observation is stakeholder consultation, feeding into an analysis of the real need. It informs the brief rather than generating design concepts or testing a built outcome.

Question 3Technological Practice

Which statement best describes a specification in technological practice?

  1. A list of materials purchased for the project
  2. A measurable requirement the outcome must meet to be judged successful Correct answer.
  3. A rough idea sketched early in the process
  4. A diary entry recording what the technologist did each day

Explanation

Specifications are testable requirements derived from the brief, such as dimensions, performance targets, or safety criteria. They allow the final outcome to be evaluated objectively against agreed criteria.

Question 4Technological Practice

During planning, a technologist identifies tasks, sequences them, and estimates the time each will take. What is this planning activity called?

  1. Concept screening
  2. Project scheduling Correct answer.
  3. Quality assurance
  4. Stakeholder mapping

Explanation

Project scheduling orders tasks over time and allocates duration to each, creating a plan that can be tracked. It is distinct from evaluating concepts or checking finished quality.

Question 5Technological Practice

A technologist builds a small-scale model of a chair to check its proportions before full construction. What is the main purpose of this model?

  1. To calculate the exact material cost of the finished chair
  2. To replace the need for any written specifications
  3. To serve as the final product delivered to the client
  4. To evaluate form and proportion before committing to full-scale making Correct answer.

Explanation

A scale model is a modelling technique used to explore and communicate form, proportion, and fit early in development. It reduces risk before expensive full-scale construction and does not substitute for specifications.

Question 6Technological Practice

Why is ongoing stakeholder feedback valuable throughout technological practice rather than only at the end?

  1. It guarantees the outcome will require no further modification
  2. It allows the technologist to adjust decisions before problems become expensive to fix Correct answer.
  3. It ensures the project will finish ahead of schedule
  4. It removes the need to write specifications for the outcome

Explanation

Feedback gathered iteratively lets the technologist refine the brief, concepts, and prototype while changes are still cheap. It informs decisions but cannot guarantee a perfect outcome or a faster schedule.

Question 7Technological Practice

Which action best demonstrates safe and responsible practice when using workshop machinery during making?

  1. Following the documented safety procedure and using the required guards and protective equipment Correct answer.
  2. Removing guards to reach the workpiece more easily
  3. Working quickly to finish before the workshop closes
  4. Asking an untrained peer to operate the machine

Explanation

Responsible technological practice requires following safety procedures, using guards, and wearing appropriate protective equipment. Speed, convenience, or delegating to untrained people all increase risk.

Question 8Technological Practice

A technologist records decisions, changes, and reasons for them throughout a project. What is the main value of this record?

  1. It replaces consultation with stakeholders
  2. It proves the outcome will automatically meet all specifications
  3. It removes the need to evaluate the final outcome
  4. It provides evidence of the decision-making process that can justify and review choices Correct answer.

Explanation

Documenting decisions and their rationale creates an audit trail that supports reflection and justifies choices to stakeholders or assessors. It does not by itself demonstrate that specifications are met, which requires evaluation.

Question 9Technological Practice

A brief states the outcome must be usable by people with limited hand strength. Which specification best operationalises this requirement?

  1. The handle is similar to a competitor's design
  2. The handle looks modern and attractive
  3. The handle is made from recycled plastic
  4. The handle can be operated with a grip force of no more than 15 newtons Correct answer.

Explanation

A specification must be measurable and testable against the stated need, so a quantified grip-force limit directly operationalises limited hand strength. Aesthetic or material statements do not test usability for this group.

Question 10Technological Practice

A technologist compares three concepts against weighted criteria such as cost, durability, and ease of use. Which practice is being applied?

  1. Random selection of the most familiar concept
  2. Copying the most expensive concept
  3. Choosing the concept that looks best in a sketch
  4. Decision-making using a weighted comparison matrix Correct answer.

Explanation

Weighting criteria and scoring concepts against them is a structured decision-making method that makes trade-offs explicit and defensible. It is more rigorous than selecting by familiarity, cost, or appearance alone.

Question 11Technological Practice

A prototype fails a durability test. What is the most appropriate next step in technological practice?

  1. Abandon the project entirely
  2. Deliver the prototype to the client without changes
  3. Remove the durability specification so the prototype passes
  4. Analyse why it failed, then modify the design or materials and retest Correct answer.

Explanation

Iterative development treats failure as information: the technologist diagnoses the cause, refines the design, and retests against the specification. Removing a specification or delivering a known failure undermines the brief.

Question 12Technological Practice

Which pair correctly matches a planning tool to its function in technological practice?

  1. Gantt chart - showing task durations and dependencies over time Correct answer.
  2. Technical drawing - recording stakeholder interviews
  3. Mood board - calculating material costs
  4. Risk register - sketching alternative concepts

Explanation

A Gantt chart displays tasks along a timeline with their durations and dependencies, supporting scheduling. The other pairings confuse tools with unrelated functions.

Question 13Technological Practice

A technologist must choose between a cheaper material with a short lifespan and a costlier material that lasts much longer. Which consideration best reflects sustainable technological practice?

  1. Choosing the costlier option because it is more expensive
  2. Ignoring both materials and selecting a third at random
  3. Assessing whole-of-life impacts, including replacement frequency and disposal Correct answer.
  4. Choosing the cheaper option regardless of lifespan

Explanation

Sustainable practice weighs impacts across the whole life cycle, so a longer-lasting material may reduce replacement and waste despite a higher upfront cost. Decisions should be based on evidence, not price alone or arbitrary choice.

Question 14Technological Practice

Before adopting a novel mechanism, a technologist checks whether a similar patented mechanism already exists. Which practice does this represent?

  1. Consulting stakeholders about aesthetics
  2. Checking intellectual property to avoid infringement Correct answer.
  3. Scheduling the production phase
  4. Testing the prototype for durability

Explanation

Reviewing existing patents and registered designs is intellectual property checking, which helps avoid infringement and informs legal use of ideas. It is separate from physical testing, aesthetic consultation, or scheduling.

Question 15Technological Practice

A technologist gathers feedback from a focus group but the participants are all from one age group, while the brief targets all ages. What is the main weakness of this evidence?

  1. The sample is not representative of the intended user group Correct answer.
  2. The feedback was collected too quickly to be useful
  3. The evidence is too expensive to analyse
  4. The focus group method cannot produce any opinions

Explanation

Evidence is only as useful as its relevance to the brief, and a single-age sample cannot represent a whole-age target population. The issue is representativeness, not speed, method validity, or cost.

Question 16Technological Practice

Which action best shows that a technologist has evaluated an outcome against its brief?

  1. Describing how attractive the outcome looks to the technologist
  2. Stating that the outcome was completed on time
  3. Listing the tools used during construction
  4. Testing the outcome against each specification and reporting the results against the original need Correct answer.

Explanation

Evaluation judges the outcome against the specifications and the original need, using evidence from testing. Appearance, tool lists, and timeliness do not demonstrate fitness for the brief.

Question 17Technological Practice

A technologist produces technical drawings and assembly instructions alongside the outcome. Why are these documents part of technological practice?

  1. They replace the need for a physical prototype
  2. They prove the outcome has no faults
  3. They are only required for aesthetic products
  4. They communicate the design so others can manufacture, use, or maintain the outcome Correct answer.

Explanation

Technical documentation communicates design intent, dimensions, and assembly so the outcome can be reproduced, used, or maintained by others. It supports rather than replaces prototyping or evaluation.

Question 18Technological Practice

A client changes the requirements midway through development. What is the most appropriate response in technological practice?

  1. Immediately rebuild everything without consulting anyone
  2. Ignore the change and continue with the original plan
  3. Review the brief and specifications with the client, then assess the impact on scope, time, and resources Correct answer.
  4. Cancel the project because the brief has changed

Explanation

Managing change means revisiting the brief and specifications with the client and assessing consequences for scope, schedule, and resources before acting. Ignoring, acting rashly, or cancelling all bypass proper decision-making.

Question 19Technological Practice

A technologist uses computer-aided design (CAD) to simulate stress on a bracket before manufacturing it. What is the main advantage of this approach?

  1. It removes the need to define specifications
  2. Potential failures can be identified and designs refined before costly physical production Correct answer.
  3. It guarantees the physical bracket will never fail
  4. It eliminates the need for any physical testing

Explanation

Simulation allows rapid iteration and reveals likely failure points before material and machine time are committed. It informs but cannot guarantee real-world performance, so physical verification remains important.

Question 20Technological Practice

A technologist claims a design is 'innovative' but presents only minor colour changes to an existing product. Which critique best applies?

  1. The claimed innovation is not substantiated because the change does not address a new need or function Correct answer.
  2. The design cannot be evaluated because it is a product
  3. The claim is valid because colour is a specification
  4. The design is innovative because any change counts as innovation

Explanation

Innovation implies a meaningful new approach that adds value or addresses a need in a new way, so cosmetic changes alone do not substantiate the claim. Evaluation should test claims against evidence and the brief.

Question 21Technological Practice

Two concepts score equally in a weighted matrix. Which next step is most consistent with sound technological decision-making?

  1. Gather further evidence or prototype both to resolve the tie against the specifications Correct answer.
  2. Flip a coin and record the result as the rationale
  3. Select the one suggested by the most senior person without discussion
  4. Combine both concepts regardless of whether they are compatible

Explanation

When structured comparison cannot separate concepts, additional evidence or prototyping provides the basis for a defensible decision. Authority, chance, or forced combination are not sound justifications.

Question 22Technological Practice

A technologist's outcome meets every specification but users find it confusing to operate. How should this be interpreted in technological practice?

  1. The users are at fault for not reading the instructions
  2. The specifications were incomplete because usability with real users was not adequately captured Correct answer.
  3. The brief should be discarded as irrelevant
  4. The outcome is a success because specifications were met

Explanation

Specifications should reflect the real need, including usability, so a product that meets written criteria but confuses users signals a gap in the brief and specifications. The response is to review the requirements, not blame users or dismiss the brief.

Question 23Technological Practice

A project is behind schedule because a key material arrived late. Which response best demonstrates reflective technological practice?

  1. Identify the cause, adjust the plan and communicate the impact to stakeholders, then record lessons for future projects Correct answer.
  2. Blame the supplier and make no changes to the plan
  3. Conceal the delay from the client until the deadline
  4. Reduce testing to make up time without telling anyone

Explanation

Reflective practice involves diagnosing causes, adapting the plan transparently, informing stakeholders, and capturing lessons to improve future work. Concealment, cutting quality checks, or blame without adjustment are poor practice.

Question 24Technological Practice

A technologist wants to reduce the environmental impact of a product. Which approach best reflects a whole-of-life perspective?

  1. Focusing only on the product's appearance in use
  2. Choosing the material with the lowest purchase price only
  3. Selecting materials and processes that lower impact across sourcing, manufacture, use, and end-of-life Correct answer.
  4. Ignoring disposal because it happens after sale

Explanation

Whole-of-life thinking considers impacts at every stage, from raw material sourcing through manufacture, use, and disposal or recycling. Optimising a single stage, such as price or appearance, can shift rather than reduce overall impact.

Question 25Technological Practice

A technologist argues that because a prototype worked once in a controlled test, the design is proven for all users. Which criticism is most valid?

  1. The design is proven because a prototype was built
  2. Controlled tests are always invalid evidence
  3. One successful test is sufficient proof for any design
  4. A single controlled test does not establish reliability across varied users and conditions Correct answer.

Explanation

Reliability requires evidence across representative users, conditions, and repetitions; a single controlled trial is weak evidence. Controlled tests are useful but limited, and building a prototype is not itself proof of fitness.

Question 26Technological Practice

In technological practice, what is the primary purpose of a brief when starting a project?

  1. To list the tools that will be used during the manufacturing stage
  2. To record the final selling price of the completed outcome
  3. To describe the qualifications of the technologist undertaking the work
  4. To define the need, the intended users, and the constraints the outcome must satisfy Correct answer.

Explanation

A brief establishes the problem space: it identifies the need or opportunity, the stakeholders, and the constraints and specifications that will later be used to judge fitness for purpose. It is written early and becomes the reference against which the outcome is evaluated. Tools, pricing and personal qualifications belong to later planning or to separate documentation.

Question 27Technological Practice

A technologist is deciding how to test whether a new drink bottle lid is easy to open. Which approach best fits the concept of fitness for purpose?

  1. Ask a representative sample of intended users to open and close the lid and record their experiences Correct answer.
  2. Measure the lid's diameter with vernier calipers and compare it with the previous model
  3. Ask the technologist's own family to try the lid once at home
  4. Read online reviews of similar lids sold by competing manufacturers

Explanation

Fitness for purpose is judged by how well an outcome performs for its intended users in realistic conditions, so testing with a representative sample of those users is the strongest evidence. Physical measurement alone does not show usability, and competitor reviews describe other products. A small, unrepresentative group such as family members gives weak, biased evidence.

Question 28Technological Practice

Which statement best describes the role of a specification in technological practice?

  1. It is a list of every possible idea the technologist considered
  2. It is the final report written after the outcome has been sold
  3. It is a measurable statement of what the outcome must achieve, used to judge success Correct answer.
  4. It is a rough sketch made before any research has been carried out

Explanation

Specifications translate the brief into testable requirements, such as a maximum mass, a minimum lifespan or a required user group. Because they are measurable, they allow the technologist and stakeholders to judge objectively whether the outcome is fit for purpose. Sketches, reports and idea lists are different artefacts with different functions.

Question 29Technological Practice

During the making stage, a technologist keeps a running record of materials used, machine settings and time taken. Which purpose does this record most directly serve?

  1. It replaces the need to test the outcome against the specifications
  2. It guarantees the outcome will meet all health and safety requirements
  3. It provides evidence for planning future production and for evaluating the efficiency of the process Correct answer.
  4. It removes the need to consult stakeholders about the outcome

Explanation

Production records capture the actual resources and settings used, which supports accurate planning of future runs and evaluation of process efficiency. They are evidence about the making process, not a substitute for testing the outcome. Health and safety compliance and stakeholder consultation are separate obligations.

Question 30Technological Practice

A technologist needs to decide whether a proposed outcome is ethical to release. Which consideration is most directly relevant to technological practice?

  1. Whether the technologist personally finds the outcome attractive
  2. Whether the colour scheme matches current retail trends
  3. Whether the outcome could cause foreseeable harm to users or bystanders when used as intended Correct answer.
  4. Whether a competitor has released a similar product this year

Explanation

Ethical decision-making in technological practice centres on foreseeable harms and benefits to users and others affected by the outcome. A technologist has a responsibility to identify risks and mitigate them before release. Aesthetic preference, retail trends and competitor timing are commercial or personal matters, not ethical analysis of harm.

Question 31Technological Practice

A technologist is choosing between two joining methods for a load-bearing frame. Which action best reflects critical evaluation of the options?

  1. Compare the strength, cost and repairability of each method against the specifications before choosing Correct answer.
  2. Choose the cheaper method because budget is always the deciding factor
  3. Choose the method the technologist has used most often in previous projects
  4. Choose the method that looks neatest in the assembled frame

Explanation

Critical evaluation requires comparing options against the specifications that matter for the outcome, such as strength, cost and repairability. Habit, cost alone and appearance are single-factor shortcuts that ignore other requirements. Weighing multiple criteria against the brief is what makes the decision defensible.

Question 32Technological Practice

What does the term 'stakeholder' mean in technological practice?

  1. Any person or group affected by or interested in the outcome and the process that produces it Correct answer.
  2. Any supplier who provides raw materials to the workshop
  3. Only the person who pays for the finished outcome
  4. Only the technologist who designs and makes the outcome

Explanation

Stakeholders include everyone with an interest in or affected by the outcome, such as users, clients, manufacturers, regulators and the wider community. Consulting them helps the technologist understand needs and consequences beyond their own view. Payers, the technologist and suppliers are each a subset, not the whole category.

Question 33Technological Practice

A technologist reviews a completed project and asks, 'What would I do differently next time and why?' Which aspect of technological practice does this question address?

  1. Calculation of the retail markup
  2. Reflection on the process to inform future practice Correct answer.
  3. Compliance with copyright law
  4. Selection of the correct fastener size

Explanation

Reflection involves analysing what happened, why decisions were made and what could be improved, so that future practice becomes more effective. The question is about learning from the process rather than about legal, technical or commercial details. Reflection is a deliberate, documented part of technological practice.

Question 34Technological Practice

A technologist is planning a project and wants to identify which tasks depend on others before they can begin. Which planning approach is most suitable?

  1. A mood board of colours and textures for the outcome
  2. A Gantt chart showing tasks, durations and dependencies along a timeline Correct answer.
  3. A bill of materials listing every component required
  4. A risk assessment register recording hazards in the workshop

Explanation

A Gantt chart displays tasks against a timeline and makes dependencies and sequencing visible, which is exactly what is needed to plan order of work. A mood board communicates aesthetic direction, a bill of materials lists components, and a risk register records hazards. Only the Gantt chart addresses task dependency.

Question 35Technological Practice

A technologist is trialling a new sustainable packaging material. Which evidence would most strongly support a claim that it is more environmentally sound than the current material?

  1. A life-cycle comparison covering raw material extraction, manufacture, transport and disposal Correct answer.
  2. A photograph showing the new material looks natural in the hand
  3. A single measurement showing the new material is lighter than the current one
  4. A supplier's marketing brochure describing the material as eco-friendly

Explanation

Environmental claims are only defensible when the whole life cycle is compared, because impacts shift between stages such as extraction, manufacture, transport and disposal. A single attribute like mass, or a supplier's promotional statement, does not establish an overall improvement. Visual appearance carries no environmental information.

Question 36Technological Practice

A technologist needs to communicate a design to a manufacturer who will not meet in person. Which documentation is most appropriate?

  1. Dimensioned technical drawings with tolerances and a materials specification Correct answer.
  2. A verbal description recorded on a phone
  3. A collection of early concept sketches in pencil
  4. A written paragraph describing the outcome in general terms

Explanation

Manufacturing requires unambiguous information: dimensions, tolerances, materials and finishes must be specified so the maker can produce the intended outcome without guessing. Concept sketches, general descriptions and verbal notes all leave critical detail open to interpretation. Technical drawings and specifications are the standard means of precise communication.

Question 37Technological Practice

A technologist is deciding whether to use a new adhesive in a product that will be exposed to heat. Which action best demonstrates responsible technological practice?

  1. Choose the adhesive that sets fastest so the project finishes sooner
  2. Assume the adhesive will perform because the supplier describes it as high strength
  3. Apply the adhesive without testing because it is cheaper than the current one
  4. Test the adhesive under expected operating temperatures and review its safety data before committing Correct answer.

Explanation

Responsible practice means gathering evidence about performance under realistic conditions and understanding the material's hazards before use. Supplier claims, cost and speed are not substitutes for testing in the intended environment. Safety data informs handling and informs whether the material is appropriate at all.

Question 38Technological Practice

A technologist's stakeholder feedback shows that users want a smaller outcome, but a key specification requires a minimum size for safety. What is the most appropriate response?

  1. Abandon the project because the requirements conflict
  2. Investigate ways to meet the safety requirement while addressing user concerns, and document the trade-off Correct answer.
  3. Reduce the size immediately to satisfy the users
  4. Ignore the feedback because a specification already exists

Explanation

When stakeholder desires conflict with a mandatory specification, the technologist must reconcile them through design work and justify any trade-off in the documentation. Safety requirements cannot simply be overridden by preference, and ignoring feedback or abandoning the project are premature. Documenting the reasoning keeps the decision transparent and reviewable.

Question 39Technological Practice

A technologist is developing a product for a market where a nearly identical patented design exists. Which course of action is most consistent with sound technological practice?

  1. Proceed with the design because patents only apply to large companies
  2. Copy the patented design and change the colour to avoid infringement
  3. Rely on the fact that the patent holder is unlikely to notice
  4. Investigate the scope of the existing patent and design around it or seek licensing advice Correct answer.

Explanation

Intellectual property must be respected, so a technologist investigates the existing protection and either designs around it or seeks advice on licensing. Patents apply regardless of company size, and trivial changes such as colour do not avoid infringement. Hoping not to be noticed is not a legal or ethical strategy.

Question 40Technological Practice

A technologist uses rapid prototyping to produce several physical versions of a handle before final manufacture. What is the main advantage of this approach in technological practice?

  1. It allows ergonomic and functional problems to be found and corrected before committing to production tooling Correct answer.
  2. It makes the final manufacturing stage unnecessary
  3. It guarantees the final product will require no further testing
  4. It removes the need to consult stakeholders about the design

Explanation

Rapid prototyping lets the technologist hold and test iterations cheaply and quickly, so faults are found before expensive production tooling is made. It supports the iterative nature of technological practice but does not eliminate later testing, stakeholder input or manufacturing. Each prototype generates information that informs the next version.

Question 41Technological Practice

A technologist is selecting software to model a complex assembly. Which criterion is most directly relevant to technological practice?

  1. Whether the software is the most popular among students
  2. Whether the software has the most attractive user interface
  3. Whether the software can represent the assembly's parts, motion and tolerances accurately Correct answer.
  4. Whether the software is the newest release available

Explanation

The purpose of modelling is to predict how the outcome will behave, so accuracy in representing parts, motion and tolerances is the decisive criterion. Interface appeal, popularity and recency may influence adoption but do not determine whether the model is technically fit for purpose. Selecting tools by their fitness for the modelling task is central to sound practice.

Question 42Technological Practice

A technologist produces a risk assessment before beginning a making task. Which element is essential for the assessment to be useful?

  1. Assigning the assessment to the least experienced person in the workshop
  2. Recording only the hazards that have caused injury in the past
  3. Identifying each significant hazard, its likelihood and severity, and the control that will reduce it Correct answer.
  4. Listing every tool in the workshop regardless of whether it will be used

Explanation

A useful risk assessment identifies significant hazards and evaluates likelihood and severity so that proportionate controls can be put in place. Listing irrelevant tools or only historical injuries misses hazards specific to the task, and giving the task to the least experienced person undermines the assessment's reliability. The link between hazard, risk and control is what makes it functional.

Question 43Technological Practice

A technologist finds that a chosen manufacturing process cannot achieve the tolerance specified for a critical part. What is the most appropriate response?

  1. Change the specification to match whatever the process produces without consultation
  2. Review whether the tolerance is genuinely required or select a process that can achieve it, then record the decision Correct answer.
  3. Loosen the tolerance silently so the part passes inspection
  4. Continue with the process and hope the parts fall within tolerance

Explanation

Tolerance and process must be compatible, so the technologist either justifies relaxing the tolerance or changes the process, and documents the reasoning. Silently loosening tolerances or hoping for compliance removes control over quality. Altering a specification without consultation undermines the brief and stakeholder agreement.

Question 44Technological Practice

A technologist is evaluating whether an outcome is innovative. Which evidence best supports that judgement?

  1. The outcome was produced by a well-known manufacturer
  2. The outcome solves the identified need in a way that is demonstrably new compared with existing solutions Correct answer.
  3. The outcome was completed faster than the planned schedule
  4. The outcome uses the most expensive materials available

Explanation

Innovation is judged by novelty combined with usefulness: the outcome must address the need in a way that differs meaningfully from existing solutions. Cost, speed and the reputation of the maker are unrelated to whether the solution is new. Comparing against existing solutions is the evidence that establishes the claim.

Question 45Technological Practice

A technologist must decide when a prototype is ready to be shown to stakeholders. Which condition is most appropriate?

  1. When every cosmetic detail has been finished to production standard
  2. When it demonstrates the key functions under representative conditions and known limitations are documented Correct answer.
  3. When it has been built, regardless of whether it has been tested
  4. When the budget for the project has been fully spent

Explanation

A prototype is ready for stakeholder review when it can demonstrate the functions being evaluated and when its known limitations are transparent, so feedback is informed and useful. Cosmetic finish and budget exhaustion are unrelated to readiness. Presenting an untested prototype invites feedback that cannot be trusted.

Question 46Technological Practice

A technologist is deciding between repairing a returned product and redesigning the faulty component. Which analysis best supports the decision?

  1. Choose redesign because it always produces a better product
  2. Choose repair because it always costs less than redesign
  3. Compare the root cause of the failure with the cost and effectiveness of each option over the product's remaining life Correct answer.
  4. Count how many products have been returned without investigating why

Explanation

Sound decisions rest on understanding the root cause and weighing the cost and effectiveness of each option across the product's remaining life. Return counts alone do not reveal why failures occur, and assuming that one option is always cheaper or always better ignores the specific evidence. Root-cause analysis connects the decision to the actual problem.

Question 47Technological Practice

A technologist is choosing between two materials with similar performance. One has a supply chain that depends on a single overseas supplier. How should this risk influence the decision?

  1. It should be weighed as a supply risk alongside performance, cost and sustainability criteria Correct answer.
  2. It should be ignored because material performance is the only relevant criterion
  3. It should decide the choice immediately against the single-supplier material
  4. It should be left to the supplier to manage without informing the decision

Explanation

Supply continuity is a legitimate criterion in technological decision-making because a single-source dependency can halt production and affect the outcome's availability. It should be evaluated alongside, not instead of, performance, cost and sustainability. Ignoring it or letting it override all other criteria are both unbalanced responses.

Question 48Technological Practice

A technologist claims an outcome is sustainable because it is recyclable. Which criticism of this claim is most valid in a whole-of-life analysis?

  1. The claim is valid because recyclable products always have lower carbon emissions
  2. Recyclability is irrelevant because recycling never recovers any material
  3. The claim is valid because recycling is the only life-cycle stage that matters
  4. Recyclability does not show that the outcome's production and use stages have low environmental impact Correct answer.

Explanation

Recyclability addresses only the end-of-life stage, so it cannot by itself establish that the whole life cycle has low impact; production energy, material sourcing and use-phase impacts must also be assessed. Recycling does recover material, so dismissing it entirely is wrong, and assuming recyclable products always have lower emissions is an unsupported generalisation. A valid sustainability claim is supported by evidence across all stages.

Question 49Technological Practice

Two stakeholder groups give contradictory feedback on a proposed outcome. Which approach best reflects mature technological practice?

  1. Adopt the feedback from the larger group without further analysis
  2. Discard both sets of feedback to avoid making a judgement
  3. Adopt the feedback from the group that is easiest to contact
  4. Analyse the basis of each group's feedback against the brief and specifications, then justify which requirements take priority Correct answer.

Explanation

Contradictory feedback requires analysis of why each group holds its view and how each view relates to the brief and specifications, followed by a justified decision. Majority size and ease of contact are not valid grounds for prioritising requirements, and discarding feedback avoids the technologist's responsibility. The reasoning should be documented so the decision can be reviewed.

Question 50Technological Practice

A technologist is evaluating whether an outcome is genuinely fit for purpose for a client who will use it in a remote location with no maintenance support. Which factor most strongly affects the judgement?

  1. The outcome's reliability and service life under conditions where repair is impossible Correct answer.
  2. The number of features included in the outcome
  3. The speed with which the outcome was manufactured
  4. The outcome's visual appeal compared with rival products

Explanation

Fitness for purpose depends on the context of use, and where maintenance is impossible, reliability and service life become decisive. Visual appeal, manufacturing speed and feature count do not address the client's inability to repair the outcome. The evaluation must reflect the actual conditions in which the outcome will operate.
