Feasibility studies — AQA A-Level Design and Technology

A feasibility study is a critical evaluation process used in design and technology to assess the viability of a proposed project before committing significant resources. It systematically examines technical, economic, legal, operational, and scheduling factors to determine whether a design idea can be successfully realised. For AQA A-Level Design and Technology, understanding feasibility studies is essential because it bridges initial concept generation and detailed design development, ensuring that students can justify their design decisions with evidence-based reasoning.

Feasibility studies typically involve five key areas: technical feasibility (can it be built with available materials and processes?), economic feasibility (is it cost-effective and profitable?), legal feasibility (does it comply with regulations and standards?), operational feasibility (will it work in the intended environment?), and scheduling feasibility (can it be completed on time?). In the context of NEA (Non-Exam Assessment), students must demonstrate that they have considered these factors to refine their design brief and specification. This topic also links to broader concepts like sustainability, risk assessment, and stakeholder analysis.

Mastering feasibility studies enables students to critically evaluate their own designs and those of others, a skill highly valued in both exams and real-world engineering. It encourages a systematic approach to problem-solving, helping students avoid common pitfalls such as over-ambitious designs or ignoring legal constraints. By integrating feasibility analysis early in the design process, students can produce more realistic, market-ready products that meet user needs effectively.

• →Technical feasibility: Assessing whether the design can be manufactured using available tools, materials, and processes, considering factors like tolerances, assembly methods, and material properties.
• →Economic feasibility: Evaluating costs (materials, labour, overheads) against potential revenue or budget, including break-even analysis and return on investment (ROI).
• →Legal feasibility: Ensuring compliance with relevant legislation (e.g., CE marking, copyright, safety standards like BS EN 71 for toys) and intellectual property rights.
• →Operational feasibility: Determining if the product will function as intended in its real-world context, including user testing, ergonomics, and environmental conditions.
• →Scheduling feasibility: Creating a realistic timeline with milestones, considering lead times for materials, manufacturing capacity, and potential delays.

• Use of feasibility studies to assess the practicality for production of proposed designs
• Testing of prototypes with potential consumers
• Interpretation of statistical analyses to determine user needs and preferences
• Use of data related to human scale and proportion to determine product scale and dimensions

• 💡In NEA projects, explicitly link your feasibility study to your design specification. Show how each feasibility factor influenced your decisions, e.g., 'Due to high material costs, I selected a cheaper alternative that still meets strength requirements.'
• 💡Use quantitative data where possible, such as cost calculations, material property tables, or time estimates. This demonstrates analytical skills and adds credibility to your feasibility arguments.
• 💡Don't forget to consider sustainability as part of feasibility. Examiners reward students who address environmental impact, lifecycle analysis, and ethical sourcing within their feasibility study.

• Misconception: Feasibility studies are only about cost. Correction: While cost is important, technical, legal, and operational factors are equally critical. A cheap product that fails safety tests is not feasible.
• Misconception: Feasibility is a one-off check at the start. Correction: Feasibility should be an iterative process revisited as the design evolves, especially when new constraints or opportunities arise.
• Misconception: If a design is technically possible, it's automatically feasible. Correction: Technical possibility does not guarantee economic viability or market acceptance. For example, a product made from rare materials may be technically feasible but economically unviable.
