Which of the following is NOT a resource when making a prototype?

When constructing a prototype, the primary resources typically include tangible items and materials necessary for the physical creation of the prototype, as well as the processes required to ensure it meets the intended design and function.

Component parts are essential because they directly become part of the prototype, contributing to its functionality and design. Cutting lists serve as detailed instructions that outline how materials should be processed and shaped, which are vital for accurate and efficient construction. Health and safety requirements are critical as they guide the designer to ensure that the prototype is safe to build and use, protecting both the maker and potential users.

Customer feedback, while incredibly valuable in the design process, does not serve as a direct resource for the physical creation of a prototype. It is primarily concerned with perceptions and insights from users or stakeholders after or during the development phase. Thus, in the context of directly contributing to making a prototype, customer feedback is not categorized as a resource in the same way the others are.
