A method and system for supply chain product and process development collaboration. The supply chain is comprised of at least one project, each project having a part (or family of parts), a supplier of the part, and a customer. The system may include a data storage and retrieval device operably connected to a processor. The system's functions include collaboration tools and security based on the users' project roles. The method uses a methodology that ensures certain requirements are met prior to satisfying the methodology. The system and method of the present invention ensures that current, applicable methodologies are applied to a specific part and allows for collaboration between the customer and supplier during all phases of the project. Because all projects in a supply chain are present, a user can navigate throughout the supply chain. The supply chain's reporting functions permit determination of potential performance risks and the source thereof.
