AQA A-Level Design and Technology: Product Design 3.2 Designing and making principles: a complete overview of the iterative process, design history, designers, users and prototyping
A deep-dive AQA A-Level Design and Technology Product Design guide to the 3.2 Designing and making principles content. Covers design methods and the iterative process, design theory and movements, the work of major designers and companies, user-centred and inclusive design, and prototyping and testing, with the knowledge and exam patterns the written papers reward.

What Designing and making principles demands
Designing and making principles (specification section 3.2) is the design-process and design-context core of the course. It is the knowledge you apply directly when you design, model and test your own product in the non-exam assessment, and it is examined in its own right in Paper 2.
This guide walks through the five areas in specification order, then sets out the exam patterns the written papers repeat. Each area has a matching dot-point page with practice questions; this overview ties them together.
Design methods and the iterative process
The section opens with the iterative design process, the cyclical explore-create-evaluate loop that has replaced the old linear model. It covers primary and secondary research, turning a design brief into a measurable design specification, generating and developing ideas, and using critical evaluation and feedback at every stage to refine the design. The central message is that iteration finds faults early, when they are cheap to fix.
Design theory, movements and designers
The course places design in its history. Design theory and movements runs from the Arts and Crafts reaction against mass production, through Art Nouveau and Art Deco, the Bauhaus and Modernism ("form follows function"), to Postmodernism and the playful Memphis group, with each shift driven by social, economic and technological change. The work of designers and companies covers influential figures and firms such as Dieter Rams (Braun), Dyson, Apple, Philippe Starck, the Eameses and Alessi, and how a brand identity and design language are built and sustained.
Users and prototyping
The final areas keep the user central. User-centred and inclusive design covers designing around the real user's needs and the wider goal of inclusive or universal design that suits as many people as possible. Prototyping and testing covers the journey from cheap sketch models, through CAD models and rapid prototypes, to functional prototypes, and how each is tested against the specification and with users to drive the next iteration.
How Designing and making principles is examined
A typical profile for the Designing and making principles paper (Paper 2):
- Design theory. Identifying movements and designers and explaining their features and influence.
- Commercial manufacture and process. Explaining design and manufacturing decisions for a commercial product.
- Product analysis. Analysing an unseen product against function, user, materials and aesthetics.
- Extended design response. Generating or developing a design and justifying decisions against a brief.
