Computer/user interface design specification for medical devices

Detailed, well organized user interface design specifications are essential to assure a smooth translation between design and implementation. Loosely defined specifications can result in the user interface being implemented differently than intended by the designer and may cause time consuming, costly modifications late in development. A good specification can facilitate the implementation process and reduce the likelihood of having to make modifications. This paper describes different approaches to developing specifications and lists the recommended contents for a design specification document
