Any changes in the infrastructure necessary for the performance of CM during the phase are accomplished and tested, including the installation of appropriate automated tools and their integration with the data environment. Personnel from all disciplines and/or integrated product teams are then trained in the overall process and in the specific procedures and tools that they will use. Training pays dividends in a smooth, seamless process in which personnel, who understand their roles and the roles of others with whom they interface, work cooperatively and treat each interfacing player as a "customer."
