Integrating UCD into your green design portfolio requires a systematic process with four main phases: research, ideation, prototyping, and evaluation. For each phase, it's important to document and showcase your methods, results, and insights. During the research phase, you should collect and analyze data about the users, the context, and the problem. You can use interviews, surveys, observations, or personas to understand user needs, motivations, and behaviors. You can also use benchmarking, SWOT analysis, or life cycle assessment to understand the environmental impact of existing or potential solutions. Present your research findings in a clear and concise way with visual aids such as charts, graphs, or diagrams. The ideation phase involves generating and selecting ideas for green design solutions. Brainstorming, mind mapping, or sketching can be used to explore different possibilities and concepts. Affinity diagramming, prioritization matrix, or scoring can be used to evaluate and filter ideas based on user and environmental criteria. Present your ideation process and outcomes in a creative and engaging way with visual aids such as sketches, mockups, or storyboards. The prototyping phase involves creating and testing low-fidelity or high-fidelity prototypes of green design solutions. Paper prototyping, wireframing, or 3D modeling can be used to create prototypes that represent key features and functions of solutions. Usability testing, user feedback, or heuristic evaluation can be used to test prototypes with users and measure their performance and satisfaction. Present your prototyping process and results in a realistic and informative way with visual aids such as screenshots, photos, or videos. Finally, the evaluation phase involves measuring and communicating the impact and value of green design solutions. Surveys, interviews, or analytics can be used to collect quantitative and qualitative data about user and environmental outcomes of solutions. Case studies, testimonials, or stories can be used to tell compelling narratives about benefits and challenges of solutions. Present your evaluation findings and recommendations in a persuasive and professional way with visual aids such as tables, charts, or infographics.
