What factors should be considered during the research phase of product design?

During the research phase of product design, it's crucial to identify the factors that will inform and shape the development of a successful product. The correct choice emphasizes essential aspects that contribute to creating a product that meets consumer needs and functions effectively in the market.

Market needs help to define what gap the product will fill, allowing designers to focus on specific problems or desires that the target audience has. Gathering user feedback ensures that the product aligns with real user experiences and expectations, leading to enhanced usability and satisfaction. Analyzing existing products is important for understanding competitive offerings, identifying strengths and weaknesses, and finding opportunities for improvement. Lastly, material availability is a practical consideration that affects the feasibility of the design; understanding what materials are accessible and their properties can influence design choices and cost.

The other options, while they may contain relevant considerations, do not encompass the comprehensive factors necessary for a thorough and effective research phase. While user feedback and product pricing are significant elements, they lack the broader context of market needs, existing offerings, and materials that form the foundation for informed design decisions.
