This new way of being competitive would still have the advantages of a vertically integrated organization as well as the flexibility and lower overhead of such a network. These flexible networks will be both local and regional and will utilize national server nodes for materials, product design, and process development with access by OEMs and their suppliers provided over the national electronic suDerhiPh way.

The refined process design is then electronically passed to the detail design stage, where most of the engineering effort is spent. The design activity that was briefly described above introduces a new design concept called soft optimization' awl soft automation:.

The shell development environment was used to create the workflow process model; to implement analytical code to analyze application output and apply design constraints; to prepare input; monitor status; to retrieve output of application on heterogeneous computers; and to suspend or initiate workflow process for different specialists based on the current state of design. An overview of the method for blade design with the subprocesses for the different roles is given in Figure D - .
