Which of the following is a requirement of a design specification?

A design specification serves as a detailed document that outlines the necessary requirements, features, and constraints of a product or system. One of the key requirements is to focus on user needs and ergonomics. This aspect ensures that the design is user-centered, meaning it is tailored to meet the demands, preferences, and expectations of the end-users. User needs encompass functionality, ease of use, and overall satisfaction, while ergonomics deals with how the design accommodates human interaction, promoting comfort, safety, and efficiency.

Focusing on user needs and ergonomics in design specifications is vital because it directly influences the usability and acceptance of the product in the market. A design that neglects these considerations risks leading to a product that could be difficult to use or uncomfortable, undermining its market viability.

The other options, such as product pricing details, marketing strategy, or supplier information, play important roles in the broader context of product development but do not constitute a core requirement of the design specification itself. Pricing and marketing strategies come into play later in the product life cycle, while supplier information pertains to sourcing materials or components rather than defining the product's design parameters.
