Core Concepts & Theory

The Internal Assessment (IA) Design Project is a comprehensive documentation process that demonstrates your design thinking and problem-solving abilities through systematic inquiry and creative development.

Key Terminology

Design Brief: A concise statement identifying the problem, target audience, and design opportunity. It answers "What needs to be designed and for whom?"

Design Specification: Measurable criteria against which the final product will be evaluated. These include performance requirements, constraints (time, materials, cost), and success metrics.

Iterative Design Process: A cyclical approach involving continuous refinement through testing, evaluation, and modification. Not linear but recursive.

Formative Testing: Ongoing evaluation during development to inform design decisions and improvements.

Summative Evaluation: Final assessment measuring how well the solution meets specification criteria.

Primary Research: First-hand data collection (surveys, interviews, observations, testing).

Secondary Research: Existing information from books, journals, websites, or product analysis.

Documentation Framework

Your IA follows the design cycle: Inquiring & Analyzing → Developing Ideas → Creating the Solution → Evaluating. Each stage requires specific evidence:

• Analysis: Research findings, specification development
• Development: Sketches, CAD models, prototype iterations
• Creation: Manufacturing logs, photographic evidence, technical drawings
• Evaluation: Testing results, client feedback, reflective commentary

Remember: Documentation should be concurrent with the design process, not retrospective. The examiner wants to see your thinking evolve, including wrong turns and corrections.

Formula for Success = Depth of Analysis + Quality of Development + Technical Execution + Critical Evaluation

Detailed Explanation with Real-World Examples

The Documentation Journey

Think of your IA documentation as a design autobiography—it tells the story of how your solution evolved. Professional designers at firms like IDEO or Dyson maintain similar records called "design portfolios" to justify decisions to clients and stakeholders.

Real-World Connection: The Dyson Vacuum Story

James Dyson created 5,127 prototypes before perfecting his bagless vacuum. His documentation tracked:

• Each iteration's performance data
• Why modifications were needed
• Technical drawings showing cyclone improvements
• Testing results comparing suction power

Your IA mirrors this professional practice on a smaller scale.

Practical Application: Sustainable Phone Case Design

Scenario: Designing an eco-friendly phone case for teenagers.

Research Phase (Real-world parallel: Market research):

• Survey 30 students about current case problems
• Analyze 5 existing products for materials and durability
• Investigate biodegradable materials (PLA, bamboo composite)

Development Phase (Like prototyping at Apple):

• Sketch 6 concepts with annotations explaining material choices
• Create CAD models testing ergonomics
• 3D print prototype, test drop resistance from 1.5m
• Document failures: "Corner cracked at 1.2m—needs reinforcement"

Evaluation Phase (Similar to product launch assessment):

• User testing: 10 students rate comfort, aesthetics, protection
• Compare against specification: "Target: biodegradable within 2 years. Result: PLA degrades in 6-24 months—SUCCESS"

Analogy: Your IA is like a recipe book that doesn't just list ingredients but explains why each ingredient matters, shows photos of each cooking stage, and honestly discusses when the soufflé collapsed.
