Abstract: A method and system for supply chain product and process development collaboration. The supply chain is comprised of at least one product, where each project is defined as a part (or family of parts), a supplier to supply the part, and a customer to be supplied the part. In one embodiment, the system includes a data storage and retrieval devise to hold project data, which, for each project, includes a project identifier, a part identified, a supplier identifier, a customer identifier, data representative of a methodology applicable to the project, and data representative of at least one control associated with processing of the project. The system and method of the present invention ensures that current methodologies applicable to a project are applied, and allows for collaboration between the customer and supplier during all phases of product and process design, development, and manufacture.
