What is included in a design specification?

A design specification is an essential document that provides a comprehensive outline of how a product or system should be constructed to meet certain requirements. It serves as a blueprint for designers and developers, detailing the necessary materials, components, systems, and processes needed to create the final product.

By focusing on a detailed description of how a product must be built, the design specification ensures that all parties involved in the development process have a clear understanding of the expectations and standards required. This includes technical specifications, performance criteria, dimensions, quality standards, and other vital information that guides the development team throughout the creation process.

In contrast, while a summary of market needs may inform the overall intent behind a product, it does not provide the required depth or technical guidance needed for construction. Similarly, a list of potential suppliers is not included in a design specification, as that relates more to sourcing than to the product's design. Lastly, design aesthetics may be a part of the overall conception of a product, but they alone do not encompass the technical and functional details required in a design specification. Thus, option B accurately captures the essence of what a design specification entails.
