Globally Networked Engineering

•Engineering organizations are globally distributed networks

•Large scale engineering organizations are moving towards system integrators and suppliers

•Collaboration across the network varies from over the wall transfer of information to joint development

•Role of information technology is still limited in-spite of success stories such as Boeing 777.

•Recent efforts in PLM/KM is encouraging as the PLM initiative is focusing on strategic business approach for the effective creation, management and use of corporate intellectual capital.

Factors in Achieving Seamless Networks of Design and Manufacturing

1. Connectivity: Bandwidth for large scale data and information transfer

2. Reach: The ability to access and provide right information that is distributed across the networked enterprise

3. Interactivity: The ability to interact with people, computational tools and physical tools across time and space

Any Cyber Infrastructure has to support along all these three dimensions
