Implementing a central service in a large organization presents challenges that are both easy to spot and difficult to predict until you start running into problems. This session is a straightforward journey of how one Fortune 500 company implemented Team Foundation Server (TFS) as a central service, migrated teams from various other platforms and managed the day-to-day operation of TFS. This includes interfacing with other parts of the organization that control various aspects of the TFS deployment even though they are not directly involved in the deployment itself. This session covers template management, security administration (including understanding the ramifications of certain decisions), training, supporting .NET and Java and mentoring as well as making your service highly available. For anyone needing to implement TFS in an organization larger than 50 people with roles split among many different departments, this session provides information you can use to avoid some of the walls that other organizations have run into.
