The design process: explore, develop, resolve (QCE Design Unit 3)
“The design process as an iterative, non-linear cycle of explore, develop and resolve - what each phase contributes, the design strategies and methods used in each, and how empathy data drives the movement between phases”
The design process has three phases - explore (investigate the need, gather empathy data, write a design brief and criteria), develop (generate, visualise and test many ideas through ideation and prototyping) and resolve (refine, evaluate against criteria, communicate and justify the final design). The process is iterative and non-linear - designers loop back to earlier phases whenever new information or testing reveals a problem. Empathy data from the identified user drives every decision. In QCE Design you are assessed on how well you apply the phases, document your decisions, and justify your final response against the needs you uncovered.

What this dot point is asking
QCAA wants you to know the three phases of the design process - explore, develop and resolve - and to be able to explain what each phase does, the strategies and methods used inside it, and how a designer moves between phases as new information arrives. The Unit 3 design challenge (IA1) and the projects (IA2, IA3) are all structured around these phases, so this is the backbone of the whole subject. Marks come from showing that you understand the process as iterative and non-linear, not a fixed checklist.
The answer
Why a process at all
Design problems are open and "wicked" - they have competing aesthetic, cultural, economic, social and technical demands, and there is no single correct answer. A repeatable process gives a designer a way to move from a vague need to a justified, communicable response without relying on a flash of inspiration. QCAA frames the process as three phases: explore, develop and resolve.
Explore
The explore phase is about understanding the problem before solving it. You investigate the context, identify the needs and wants of an identified person or group, and gather data using designing-with-empathy methods such as interviews, observation and immersive experiences. The phase produces three key artefacts:
- A clear statement of the design problem or opportunity.
- A design brief that sets out who you are designing for, the purpose, and the constraints (budget, materials, context, audience).
- Design criteria - the measurable conditions a successful response must meet, drawn directly from the needs you uncovered.
Good exploration is the difference between solving the real problem and solving an assumed one. Most weak responses fail here by jumping to a solution before the need is understood.
Develop
The develop phase is where ideas are generated and tested. You use ideation strategies (brainstorming, sketching, mind-mapping, SCAMPER, morphological analysis) to produce a wide range of possibilities, then visualise them through annotated drawings, models and low-fidelity prototypes. The aim is breadth first, then convergence: generate many ideas, then narrow toward the strongest using the design criteria. Prototyping and testing in this phase produce evidence that feeds decisions - a prototype that fails a user test sends you back to explore or to a new idea.
Resolve
The resolve phase refines the chosen idea into a final design proposal. You produce high-fidelity visualisations or models, evaluate the design against the criteria set in explore, and communicate and justify the response to the client or audience. Justification is critical in QCE Design - you must show how the final design meets the identified needs and why your decisions are defensible. This phase produces the design proposal that is judged in assessment.
Iterative and non-linear
The phases are not a one-way pipeline. The process is iterative - you cycle through ideas, refining repeatedly - and non-linear, meaning you can move backwards as well as forwards. Testing a prototype in develop might reveal that you misread the need, sending you back to explore. Evaluating against criteria in resolve might expose a gap that demands a new develop loop. QCAA explicitly describes good design as emerging "through an iterative process of refinement" rather than a predetermined sequence of steps. Showing this looping in your documentation is exactly what high-band responses do.
How empathy data drives the phases
In Unit 3 the engine of the whole process is empathy. The data you gather in explore - what the user said, did, felt and needed - becomes the criteria you develop against and the standard you resolve against. Every decision should trace back to a user need. When a marker reads your folio, they are checking that the line from "this person needs X" to "my design does Y" is unbroken.
Documentation and the role of the folio
In QCE Design you are assessed not just on the final object but on the journey. The design folio records each phase: the empathy data, the brief and criteria, the breadth of ideation, the testing evidence, and the final justified proposal. Markers reward clear evidence of decision-making at each phase and clear linkage between phases. A beautiful final render with no documented exploration scores poorly.
Worked design-challenge walkthrough
Brief: design a better way for a vision-impaired commuter to identify the correct bus at a busy stop.
Explore: interview two vision-impaired commuters and observe a peak-hour stop. Finding - audio announcements are drowned out by traffic and apps require a third hand. Criteria - hands-light operation, works in noise, no reliance on sight, low cost.
Develop: ideate widely - a haptic wristband, a tactile timetable, a directional audio beacon, a vibrating phone case. Sketch each, build a cardboard-and-motor prototype of the wristband, user-test it. The wristband confuses two bus routes - loop back and add a distinct vibration pattern per route.
Resolve: refine the wristband into a final proposal with a labelled render, a pattern key, and a costing. Evaluate against the four criteria - it is hands-light, works in noise, needs no sight, and is low cost. Justify by quoting the interview need it answers.
The visible loop from develop back to a refinement, and the criteria-by-criteria evaluation in resolve, are what lift this from a mid to a high band.
The QCE Design process is explore (understand the need and write criteria), develop (generate and test many ideas) and resolve (refine, evaluate against criteria, justify). It is iterative and non-linear - you loop back whenever new evidence demands it - and every decision should trace to an identified user need.
- Treating the phases as a fixed checklist
- Markers reward visible iteration - looping back when testing reveals a problem. A perfectly linear folio looks like the work was reverse-engineered.
- Skipping exploration
- Jumping straight to a solution is the single most common reason for a low band. Without documented empathy data, the design has nothing to justify it.
- No criteria, or criteria written after the fact
- Criteria must come from the explore phase and be used to evaluate in resolve. Inventing them at the end to flatter the design is transparent to markers.
- Confusing ideation breadth with quality
- Develop needs a genuine range of distinct ideas, not three near-identical sketches. Breadth then convergence.
- A great render with no justification
- The final design must be justified against identified needs. Presentation without linkage to the user scores poorly.
Exam-style questions
Questions in the style of QCAA exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
PracticeUse the stimulus and circular design methods to reduce the waste of equipment and improve the sustainability of a sporting club. Your response should show application of the develop phase of the design process. Devise ideas, and refine these based on your evaluation using the design criteria, to propose a design concept. Use sketches and annotations to represent your ideas and design concept.Show worked answer →
This 34-mark external assessment question is built entirely around one phase of the design process, the develop phase, which is exactly what the instruction "Your response should show application of the develop phase" demands. The explore phase is given to you in the stimulus (the context, the problem and the design criteria are supplied), and the resolve phase is not assessed here, so you must stay inside develop.
The develop phase has three moves and the question names all three:
- Devise ideas using divergent thinking, generating a genuine breadth of distinct possibilities rather than variations of one. This is the divergence the markers reward.
- Evaluate and refine the ideas against the design criteria, judging strengths and limitations and then changing attributes to improve the fit. This is the convergence move.
- Propose a design concept by synthesising the strongest devised ideas into a single coherent response that satisfies the criteria.
Because the develop phase is iterative, your sketches should show ideas progressing and being refined across the page, not a single finished answer. A high-band response makes the loop from idea to evaluation to refined concept visible.
PracticeUse the stimulus to develop a park feature for the redesigned community park. Your response should show application of the develop phase of the design process. Devise ideas, and refine these based on your evaluation using the design criteria, to propose a design concept. Use sketches with notes to represent your ideas and design concept.Show worked answer →
The external assessment isolates the develop phase, so the marks are awarded for how you move through it, not for the finished feature alone. The stimulus carries the explore work (the brief, the community context and the design criteria), leaving you to demonstrate develop end to end.
Work the phase in its natural order. First diverge: devise a wide range of ideas for the park feature, based on multiple different ways of responding to the problem, so the breadth itself scores. Then converge: evaluate those ideas against all the design criteria, identifying strengths, limitations and implications, and refine them by modifying attributes that improve the match. Finally synthesise: combine the strongest devised ideas and stimulus information into one logical, sustainable design concept that satisfies the criteria.
Show the process as iterative and non-linear. Sketches with notes should reveal ideas being tested against the criteria and looping back into refinements, because that visible movement between generating and judging is the heart of the develop phase and what lifts the response into the upper bands.
