The present invention relates generally to a comprehensive, integrated
computer-based process and method for undertaking an engineering design
and development effort in a virtual collaborative environment by
facilitating communication of specifications for parts and assemblies for
review and approval. Specifications for the fabrication of parts may be
presented and reviewed by the user. By accepting or validating the
specifications, the user may apply his/her digital signature, thereby
confirming an understanding of the specifications and, according to an
embodiment of the invention, creating a binding contract.
