NSSCAS Design and Technology (8256) study plan

Distinguish needs, wants and design briefs by rewriting three everyday product complaints into formal problem statements with client, user and constraint identified.

Construct a full product design specification for one chosen brief, separating mandatory requirements from desirable ones and stating measurable tolerances for at least eight criteria.

Sequence the iterative design cycle for that brief, annotating where research, ideation, modelling, testing and evaluation feed back into earlier stages.

Draft a client interview schedule of ten open questions that would surface unstated constraints such as budget ceiling, batch size and regulatory limits.

Generate and record at least fifteen distinct concept ideas for the week-1 brief using three different ideation techniques, showing divergence before convergence.

Apply a weighted decision matrix with at least six criteria to shortlist three concepts, and justify the weighting choices in writing.

Produce one-point-perspective and isometric sketches of the leading concept to a stated scale, with correct line weights and hidden detail conventions.

Annotate a third-angle orthographic projection of the leading concept with principal dimensions and a parts list.

Compare six candidate materials for the chosen product across density, tensile strength, stiffness, cost per kilogram, recyclability and working temperature, citing values in a table.

Match each shortlisted material to an appropriate stock form and standard section size, explaining why that form suits the intended manufacturing route.

Explain the property differences between thermoplastics and thermosetting polymers and select one of each for a named application with justification.

Identify three in-service failure risks (corrosion, fatigue, UV degradation, creep) for the chosen materials and state one mitigation for each.

Select and justify two standard components, such as fasteners or bearings, from supplier data rather than custom parts.

Map the chosen product to a manufacturing route, comparing at least three processes on tooling cost, cycle time, surface finish and economic batch size.

Calculate the break-even batch size between two candidate processes given fixed and variable cost assumptions, and state which route suits a batch of 500 units.

Write a step-by-step process plan for the selected route, naming tools, equipment, jigs or fixtures and quality checks at each stage.

Specify tolerances and surface finish callouts for three critical features and explain how each would be inspected on the shop floor.

Identify two health and safety hazards in the planned process and state the control measure for each under a hierarchy-of-controls rationale.

Conduct a lifecycle assessment of the chosen product across material extraction, manufacture, use and end-of-life, naming the highest-impact stage with evidence.

Apply the six Rs to the design and propose three concrete design changes that measurably reduce impact, such as material substitution or design for disassembly.

Evaluate the product against relevant safety, labelling and consumer protection obligations, listing four compliance points the design must satisfy.

Analyse one social or ethical issue in the supply chain, such as labour conditions or planned obsolescence, and state how the designer's decisions affect it.

Produce a disassembly plan showing fastening methods, tool access and material separation for end-of-life recycling.

Analyse the product's structure by drawing its free-body diagram and calculating reaction forces and a safety factor for the critical load-bearing member.

Select and size a mechanism for the product's moving function, calculating velocity ratio, mechanical advantage and output force for the chosen arrangement.

Describe an open-loop and a closed-loop control solution for one product function, naming sensor, controller and actuator and explaining the feedback path.

Draw and interpret a system block diagram for the product, identifying input, process, output and any feedback elements.

Explain how a cam, gear train or linkage converts motion in the design, stating the input and output motion for each.

Produce a full working drawing set for the product, including assembly drawing, detail drawings and a cutting list, checked for dimensional consistency.

Build a physical or CAD model of the product and record at least five test results against the specification criteria from week 1.

Write a critical evaluation of the outcome against each specification criterion, stating pass, partial or fail with evidence.

Revise the design in response to at least two test findings and document the change with before-and-after drawings or images.

Assemble the coursework portfolio into the required sections with a contents page and a coherent design narrative.

Audit the portfolio against the assessment criteria and log every missing piece of evidence with an action and a time estimate.

Complete all outstanding evidence gaps identified in the audit, prioritising the highest-weighted sections.

Rehearse timed exam-style answers on design process, materials and manufacturing, writing three responses of exam length under time pressure.

Summarise the twelve most error-prone facts across all domains onto a single revision sheet and self-test until recalled without notes.

Finalise and submit the portfolio, confirming file naming, page limits and submission format against the exam board requirements.
