Design Strategies & Communication
Design Strategies
The specification requires you to understand how different strategies help designers generate creative ideas and develop them into successful products. A strategy is a planned approach to solving a design problem — choosing the right one depends on the nature of the brief, the client, and the context.
Collaboration involves working with others — other designers, engineers, clients, or end users — to develop ideas. It brings together different skills and viewpoints, often producing solutions that no individual would have reached alone. In industry, product design teams typically include specialists in materials, electronics, marketing, and manufacturing.
User-centred design places the end user at the heart of every decision. The designer gathers data through interviews, observation, and usability testing, then designs specifically around those findings. This reduces the risk of creating something that looks good but fails in practice. Apple’s product design is a well-known example of this approach.
A systems approach breaks a complex product down into manageable sub-systems — typically input, process, and output. Each sub-system is designed and tested separately, then integrated. This is common in electronic and mechanical products. For example, an automatic hand dryer has an input (motion sensor), a process (control circuit), and outputs (heater element and fan motor).
The five design strategies named in the specification are: collaboration, user-centred design, a systems approach, iterative design, and avoiding design fixation.
Iterative Design & Avoiding Design Fixation
Iterative design involves repeated cycles of designing, making, testing, and evaluating. Rather than trying to produce a perfect solution first time, the designer creates quick prototypes, tests them, learns from the results, and refines the design. Each cycle gets closer to the final solution.
Design fixation occurs when a designer becomes too attached to an early idea and stops exploring alternatives. To avoid it, designers use techniques such as brainstorming, mind mapping, SCAMPER (Substitute, Combine, Adapt, Modify, Put to other use, Eliminate, Reverse), and looking at the problem from different perspectives.
Communicating Design Ideas
AQA requires you to develop, communicate, record, and justify your design ideas using a range of techniques. The method you choose depends on the audience and purpose.
Freehand sketching is used in the early stages to quickly explore ideas. Sketches are fast, informal, and often annotated with notes explaining materials, dimensions, or functions.
Isometric drawing shows a 3D view of an object with all three axes visible. Measurements are to scale, making it useful for communicating shape and proportion. Perspective drawing creates a more realistic view by using vanishing points, making objects appear to recede into the distance.
Third-angle orthographic projection is a formal engineering drawing showing front, side, and plan views. It uses conventions such as dimension lines, centre lines, and hidden detail (dashed lines), all drawn to scale. This is the standard format for working drawings that go to a manufacturer.
Exploded diagrams show how parts fit together by separating them along an axis, revealing assembly order and constructional detail. System and schematic diagrams show the logical relationships between components — circuit diagrams are a common example.
Computer-based tools include CAD (Computer Aided Design) software such as SolidWorks, Fusion 360, or 2D Design. These allow precise modelling, rendering, and even simulation of how a product will behave. Mathematical modelling uses calculations or simulations to test performance before building a physical prototype.
Physical modelling involves making 3D models from card, foam, fabric (toile), or breadboard circuits. Models help test form, proportion, and ergonomics in ways that drawings cannot.
Communication methods range from quick freehand sketches (idea generation) to formal third-angle orthographic projections (manufacture). The choice depends on the stage of the design process and the audience.
