IMAN teamcenter (TCAE- Team Center Automotive Edition) is a group of tools for managing engineering data.
Autoweb is a glorified FTP process for transferring data.
At GM, we have various levels of suppliers. A "fully collaborative supplier" is able to access the TeamCenterAutomotive Edition tool set and manipulate data from there.
For suppliers who are not fully collaborative, Autoweb is the secure and approved method of transferring data in and out GM.
