Software to support materials selection will be part of an integrated computing environment that spans the concurrent enterprise process and makes use of embedded assistance for many aspects of the product life cycle. Amidst the evolution of the business context, materials selection continues to occur in two forms: strategic materials selection and routine materials selection.

Materials knowledge is to be accessible to the engineer as reference material through design advisors that interact with the user as well as product and process models to analyze, critique, improve, or optimize it. Major tools in the integrated environment should provide the following capabilities: managing electronic repositories of data and documents; searching through past development histories to find similar or analogous products; managing interactions with other parts of the enterprise; m a n a g i n g r e q u i r e m e n t s ; p r e d i c t i n g p e r f o r m a n c e c h a r a c t e r istics; predicting manufacturing and maintenance characteristics; estimating costs; suggesting improvements to the proposed product or process description; and releasing material, product, and process descriptions to other components of the enterprise.

The Multidistance Principle has implications for the development of software tools such as computer-aided systems that enhance finding creative design solutions. These tools must be able to establish links to one or more attributes of the distant elements of the design solution as well as providing access to the more routine, detailed design features.

Imagery and externalization that aid in representing various solutions are key to bringing a wide range of information to bear on the design problem at hand. While computeraided systems have been used to enhance logical, rulebased thinking and neural networks can learn perception, the element of cognitive psychology called Insight is the key to the discovery of creative solutions to difficult design problems.
