1. Product Design Specification - PDS The Product Design Specification (PDS) is a very important document in the design process as it contains all the information necessary for a design team to successfully produce a solution to the design problem.

Safety 2.1… Categories created depends on what kind of specification is begin written. I.e. a technical specification will not focus too much on Aesthetics etc. but more on performance and components etc.

There are various kinds of Specifications depending on the focus of expertise. “The Specification is a statement of the characteristics that a design must possess in order to be a solution to the human need.” (Norman et al 2000) “A specification is essentially a means of communicating the needs or intentions of one party to another. It may be a user’s description, to a designer, of his requirements for purpose or duty; or it may be a designer's description, to a manufacturer's detailed description, to his operator, of the components, materials, methods, etc., necessary to achieve that embodiment; or it may be a statement, by a seller, describing suitability for a purpose to satisfy a need or even a potential need, of a user or a possible user. It may, of course, be some or all of these in one.” Guide to the Preparation of Specifications produced by the British Standards Institution in 1967.
