Which term refers to the list of requirements a yet-to-be-designed product must fulfil?

• A. Architectural innovation
• B. Copyright
• C. Design specification
• D. Adaptation

Answer: (C)

The design specification defines the requirements a product must fulfil before design begins. It translates user needs into clear, measurable criteria that guide decisions about function, performance, size, materials, safety, cost, and sustainability, and it sets constraints that the final design must meet. This specification also serves as a benchmark for evaluating prototypes and the finished product. The other terms don’t fit because architectural innovation relates to new methods in building design, copyright covers legal protection for original works, and adaptation means altering something for a different use rather than listing upfront requirements.
